DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Election/Restrictions
Claims 6-8, 13-15 and 20-22 are withdrawn from further consideration pursuant to 37 CFR 1.142(b), as being drawn to a nonelected species, there being no allowable generic or linking claim. Applicant timely traversed the restriction (election) requirement in the reply filed on 08/13/2025.
Applicant's election with traverse of Species B in the reply filed on 08/13/2025 is acknowledged. The traversal is on the ground(s) that they are a similar subject matter and would identify similar art. This is not found persuasive because while the field of search for one group of claims may overlap with the field of search for the other group of claims, there is no reason to expect that said fields of search would be co-extensive. Specifically, the search is not directed only to 102-type anticipatory art, but also to 103-type art pointing to the obviousness of the claimed invention. The search for 103-type art for each group of claims would cause the fields of search to diverge, creating a serious burden on the Examiner to examine all of the claims together.
The requirement is still deemed proper and is therefore made FINAL.
Claim Objections
Claims 3 and 11 are objected to because of the following informalities: quarts should be corrected to quartz. Appropriate correction is required.
Claim Interpretation
The following is a quotation of 35 U.S.C. 112(f):
(f) Element in Claim for a Combination. – An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof.
The following is a quotation of pre-AIA 35 U.S.C. 112, sixth paragraph:
An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof.
The claims in this application are given their broadest reasonable interpretation using the plain meaning of the claim language in light of the specification as it would be understood by one of ordinary skill in the art. The broadest reasonable interpretation of a claim element (also commonly referred to as a claim limitation) is limited by the description in the specification when 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is invoked.
As explained in MPEP § 2181, subsection I, claim limitations that meet the following three-prong test will be interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph:
(A) the claim limitation uses the term “means” or “step” or a term used as a substitute for “means” that is a generic placeholder (also called a nonce term or a non-structural term having no specific structural meaning) for performing the claimed function;
(B) the term “means” or “step” or the generic placeholder is modified by functional language, typically, but not always linked by the transition word “for” (e.g., “means for”) or another linking word or phrase, such as “configured to” or “so that”; and
(C) the term “means” or “step” or the generic placeholder is not modified by sufficient structure, material, or acts for performing the claimed function.
Use of the word “means” (or “step”) in a claim with functional language creates a rebuttable presumption that the claim limitation is to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites sufficient structure, material, or acts to entirely perform the recited function.
Absence of the word “means” (or “step”) in a claim creates a rebuttable presumption that the claim limitation is not to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is not interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites function without reciting sufficient structure, material or acts to entirely perform the recited function.
Claim limitations in this application that use the word “means” (or “step”) are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. Conversely, claim limitations in this application that do not use the word “means” (or “step”) are not being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action.
This application includes one or more claim limitations that do not use the word “means,” but are nonetheless being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, because the claim limitation(s) uses a generic placeholder that is coupled with functional language without reciting sufficient structure to perform the recited function and the generic placeholder is not preceded by a structural modifier. Such claim limitation(s) is/are:
The edge temperature correcting element in claim 1, interpreted as heaters 302 and 402 [0040, 0043].
Because this/these claim limitation(s) is/are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, it/they is/are being interpreted to cover the corresponding structure described in the specification as performing the claimed function, and equivalents thereof.
If applicant does not intend to have this/these limitation(s) interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, applicant may: (1) amend the claim limitation(s) to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph (e.g., by reciting sufficient structure to perform the claimed function); or (2) present a sufficient showing that the claim limitation(s) recite(s) sufficient structure to perform the claimed function so as to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph.
Claim Rejections - 35 USC § 103
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
Claim 1 is rejected under 35 U.S.C. 103 as being unpatentable over United States Patent Application No. 2015/0159272 to Yoon et al in view of United States Patent Application No. 2018/0272390 to Ulloa.
In regards to Claim 1, Yoon teaches a process kit 110, 130, 140, 300 Fig. 1-8 for use in a processing chamber 120, the process kit comprising: an inner liner 110 having: a plurality of first inlet holes 132 disposed on an injection side 130 of the inner liner and configured to be in fluid communication with a gas injection assembly 133 [0039] of a processing chamber; and a plurality of first outlet holes 142 disposed on an exhaust side 140 of the inner liner and configured to be in fluid communication with a gas exhaust assembly 143 of the processing chamber; a top plate (top of 110) and a bottom plate (bottom of 110, and 420) attached to an inner surface of the inner liner (as shown in Fig. 8B), the top plate and the bottom plate forming an enclosure together with the inner liner (as shown in Fig. 8); a cassette 300 disposed within the enclosure, the cassette comprising a plurality of shelves 330 configured to retain a plurality of substrates thereon [0031]; and an edge temperature correcting element (heat line/heater 121) [0050] disposed between the inner liner and an outer housing 120 [0028-0053].
Yoon does not expressly teach a first ring reflector disposed outside of the inner liner wherein the edge temperature correcting element is disposed between the inner liner and the first ring reflector.
Ulloa teaches a vertical processing apparatus processing chamber 110, with a plurality of first inlet holes 160 disposed on an injection side of the inner liner and configured to be in fluid communication with a gas injection assembly 140, 142, 145 of a processing chamber; and a plurality of first outlet holes 170 disposed on an exhaust side of the inner liner and configured to be in fluid communication with a gas exhaust assembly 155, 172 of the processing chamber; a top plate 122 and a bottom plate 124, the top plate and the bottom plate forming an enclosure together within 150; a cassette 120 disposed within the enclosure, the cassette comprising a plurality of shelves 250 configured to retain a plurality of substrates 200 thereon; a first ring reflector 220 disposed outside of the cassette 120; and an outer liner/chamber body 110and an edge temperature correcting element 210 (heating element which can be a resistive coil, lamp or ceramic heater [0029]) disposed on an inner circumference of reflector 220 (which is ring shaped as shown in 220 Fig. 2) which is mounted on an outer liner 110 [0018-0073].
The heater of Ulloa 210 is analogous to the edge temperature correcting element 121 of Yoon, which is mounted on an outer liner/outer housing 120, as it is a vertical heating element surrounding a cassette in a processing space to process wafers, which includes plasma treatment [0006].
It has been held that an express suggestion to substitute one equivalent component or process for another is not necessary to render such substitution obvious. In re Fout, 675 F.2d 297, 213 USPQ 532 (CCPA 1982). See MPEP 2144.06 II. Thus, it would be obvious to one of ordinary skill in the art, to change the edge temperature correcting element and outer housing chamber structure in Yoon with that of Ulloa, which includes a ring reflector 210 on an outer circumference of heater 210, such that the ring reflector is disposed outside of the inner liner, as an art analogous structure for heating, chamber walls, and reflectors. See MPEP 2143 Motivation A.
The resulting apparatus fulfills the limitations of the claim.
Claim 2 is rejected under 35 U.S.C. 103 as being unpatentable over United States Patent Application No. 2015/0159272 to Yoon et al in view of United States Patent Application No. 2018/0272390 to Ulloa, and in further view of United States Patent Application No. 2015/0013595 to Janzen et al.
The teachings of Yoon in view of Ulloa are relied upon as set forth in the above 103 rejection of Claim 1.
In regards to Claim 2, Yoon in view of Ulloa teach an outer liner (110 of Ulloa) outside of the first ring reflector but does not expressly teach the outer liner comprises opaque quartz or silicon carbide coated graphite.
Janzen teaches a chamber 1 Fig. 1, or outer liner, is made out of silicon carbide coated graphite [0033].
It has been held that the selection of a known material based on its suitability for its intended use supports a prima facie obviousness determination. See MPEP 2144.07. Sinclair & Carroll Co. v. Interchemical Corp., 325 U.S. 327, 65 USPQ 297 (1945). Therefore, because it is known to make an outer liner/chamber analogous to that of Yoon in view of Ulloa out of SiC coated graphite, as taught by Janzen, it would be prima facie obvious to one of ordinary skill in the art at the time of the invention to do so. The resulting apparatus would fulfill the limitations of Claim 2.
Claim 3 is rejected under 35 U.S.C. 103 as being unpatentable over United States Patent Application No. 2015/0159272 to Yoon et al in view of United States Patent Application No. 2018/0272390 to Ulloa, and in further view of United States Patent Application No. 2016/0348240 to Burrows et al and United States Patent Application No. 2009/0004405 to Merry et al.

Interchemical Corp., 325 U.S. 327, 65 USPQ 297 (1945). Therefore, because it is known to make an inner liner analogous to that of Yoon in view of Ulloa out of SiC coated graphite, as taught by Burrows, it would be prima facie obvious to one of ordinary skill in the art at the time of the invention to do so.
Merry teaches a cassette/boat/susceptor 168 Fig. 1 can be made out of silicon coated graphite [0034].
It has been held that the selection of a known material based on its suitability for its intended use supports a prima facie obviousness determination. See MPEP 2144.07. Sinclair & Carroll Co. v. Interchemical Corp., 325 U.S. 327, 65 USPQ 297 (1945). Therefore, because it is known to make a cassette analogous to that of Yoon in view of Ulloa out of SiC coated graphite, as taught by Merry, it would be prima facie obvious to one of ordinary skill in the art at the time of the invention to do so.
The resulting apparatus fulfills the limitations of the claim.

Yoon does not expressly teach a first ring reflector disposed outside of the inner liner wherein the edge temperature correcting element is disposed between the inner liner and the first ring reflector.
Ulloa teaches a vertical processing apparatus processing chamber 110, with a plurality of first inlet holes 160 disposed on an injection side of the inner liner and configured to be in fluid communication with a gas injection assembly 140, 142, 145 of a processing chamber; and a plurality of first outlet holes 170 disposed on an exhaust side of the inner liner and configured to be in fluid communication with a gas exhaust assembly 155, 172 of the processing chamber; a top plate 122 and a bottom plate 124, the top plate and the bottom plate forming an enclosure together within 150; a cassette 120 disposed within the enclosure, the cassette comprising a plurality of shelves 250 configured to retain a plurality of substrates 200 thereon; a first ring reflector 220 disposed outside of the cassette 120; and an outer liner/chamber body 110and an edge temperature correcting element 210 (heating element which can be a resistive coil, lamp or ceramic heater [0029]) disposed on an inner circumference of reflector 220 (which is ring shaped as shown in 220 Fig. 2) which is mounted on an outer liner 110 [0018-0073].
It has been held that an express suggestion to substitute one equivalent component or process for another is not necessary to render such substitution obvious. In re Fout, 675 F.2d 297, 213 USPQ 532 (CCPA 1982). See MPEP 2144.06 II. Thus, it would be obvious to one of ordinary skill in the art, to change the edge temperature correcting element and outer housing chamber structure in Yoon with that of Ulloa, which includes a ring reflector 210 on an outer circumference of heater 210, such that the ring reflector is disposed outside of the inner liner, as an art analogous structure for heating, chamber walls, and reflectors.

It has been held that an express suggestion to substitute one equivalent component or process for another is not necessary to render such substitution obvious. In re Fout, 675 F.2d 297, 213 USPQ 532 (CCPA 1982). See MPEP 2144.06 II. Thus it would be obvious to one of ordinary skill in the art at the time of the invention before the effective filing date to have changed the generic heating elements of Yoon with the lamps of Ulloa, as art analogous heating elements. The resulting structure would form upper and lower lamp modules, as broadly recited in the claim as it would form upper and lower areas of lamps along the vertical axis of the processing chamber.
Yoon in view of Ulloa do not expressly teach the chamber is a quartz chamber.
Burrows teaches an inner liner 2252 Fig. 2A, 2B can be made of quartz [0021].

Interchemical Corp., 325 U.S. 327, 65 USPQ 297 (1945). Therefore, because it is known to make an inner liner analogous to that of Yoon in view of Ulloa out of SiC coated graphite, as taught by Burrows, it would be prima facie obvious to one of ordinary skill in the art at the time of the invention to do so.
In regards to Claim 12, Yoon in view of Ulloa do not expressly teach the edge temperature correcting element comprises two graphite heaters surrounding the inner liner.

It has been held that an express suggestion to substitute one equivalent component or process for another is not necessary to render such substitution obvious. In re Fout, 675 F.2d 297, 213 USPQ 532 (CCPA 1982). See MPEP 2144.06 II. Thus, it would be obvious to one of ordinary skill in the art, to change the edge temperature correcting element and outer housing chamber structure in Yoon with that of Ulloa, which includes a ring reflector 210 on an outer circumference of heater 210, such that the ring reflector is disposed outside of the inner liner, as an art analogous structure for heating, chamber walls, and reflectors. See MPEP 2143 Motivation A.
Yoon does not expressly teach a plurality of upper lamp modules and a plurality of lower lamp modules.

Thus it would be obvious to one of ordinary skill in the art at the time of the invention before the effective filing date to have changed the generic heating elements of Yoon with the lamps of Ulloa, as art analogous heating elements. The resulting structure would form upper and lower lamp modules, as broadly recited in the claim as it would form upper and lower areas of lamps along the vertical axis of the processing chamber.
Yoon does not expressly teach a transfer robot configured to transfer the plurality of substrates into and from the process kit disposed in the processing chamber.
Ulloa teaches a transfer mechanism (not shown) that transfer the substrates into the processing chambers and the cassette in the form of a robot, thus transferring substrates more efficiently [0035].
As it is known to provide a transfer robot in a processing system, as taught by Ulloa, it would be obvious to one of ordinary skill in the art before the effective filing date to have modified Yoon as taught by Ulloa to include the transfer robot. One would be motivated to do so in order to move substrates as needed efficiently. See MPEP 2143, Exemplary Rationales A.
Yoon in view of Ulloa do not expressly teach the chamber is a quartz chamber.
Burrows teaches an inner liner 2252 Fig. 2A, 2B can be made of quartz [0021].
It has been held that the selection of a known material based on its suitability for its intended use supports a prima facie obviousness determination. See MPEP 2144.07. Sinclair & Carroll Co. v. Interchemical Corp., 325 U.S. 327, 65 USPQ 297 (1945). Therefore, because it is known to make an inner liner analogous to that of Yoon in view of Ulloa out of SiC coated graphite, as taught by Burrows, it would be prima facie obvious to one of ordinary skill in the art at the time of the invention to do so.
In regards to Claim 12, Yoon in view of Ulloa do not expressly teach the edge temperature correcting element comprises two graphite heaters surrounding the inner liner.
Burrows teaches heating elements 204 Fig. 2A, 2B can be made of silicon carbide coated graphite [0022].
It has been held that the selection of a known material based on its suitability for its intended use supports a prima facie obviousness determination. See MPEP 2144.07. Sinclair & Carroll Co. v. Interchemical Corp., 325 U.S. 327, 65 USPQ 297 (1945). Therefore, because it is known to make the edge temperature correcting element analogous to that of Yoon in view of Ulloa out of SiC coated graphite, as taught by Burrows, it would be prima facie obvious to one of ordinary skill in the art at the time of the invention to do so.
The resulting apparatus fulfills the limitations of the claim.
In regards to Claim 19, Yoon in view of Ulloa do not expressly teach the edge temperature correcting element comprises two graphite heaters surrounding the inner liner.
Burrows teaches heating elements 204 Fig. 2A, 2B can be made of silicon carbide coated graphite [0022].
It has been held that the selection of a known material based on its suitability for its intended use supports a prima facie obviousness determination. See MPEP 2144.07. Sinclair & Carroll Co. v. Interchemical Corp., 325 U.S. 327, 65 USPQ 297 (1945). Therefore, because it is known to make the edge temperature correcting element analogous to that of Yoon in view of Ulloa out of SiC coated graphite, as taught by Burrows, it would be prima facie obvious to one of ordinary skill in the art at the time of the invention to do so.
The resulting apparatus fulfills the limitations of the claim.
Claims 10 and 17 are rejected under 35 U.S.C. 103 as being unpatentable over United States Patent Application No. 2015/0159272 to Yoon et al in view of United States Patent Application No. 2018/0272390 to Ulloa and United States Patent Application No. 2016/0348240 to Burrows et al, and in further view of United States Patent Application No. 2015/0013595 to Janzen et al.
The teachings of Yoon in view of Ulloa and Burrows are relied upon as set forth in the above 103 rejection of Claim 1.
In regards to Claims 10 and 17, Yoon in view of Ulloa and Burrows teach an outer liner (110 of Ulloa) outside of the first ring reflector but does not expressly teach the outer liner comprises opaque quartz or silicon carbide coated graphite.
Janzen teaches a chamber 1 Fig. 1, or outer liner, is made out of silicon carbide coated graphite [0033].
It has been held that the selection of a known material based on its suitability for its intended use supports a prima facie obviousness determination. See MPEP 2144.07. Sinclair & Carroll Co. v. Interchemical Corp., 325 U.S. 327, 65 USPQ 297 (1945). Therefore, because it is known to make an outer liner/chamber analogous to that of Yoon in view of Ulloa and Burrows out of SiC coated graphite, as taught by Janzen, it would be prima facie obvious to one of ordinary skill in the art at the time of the invention to do so. The resulting apparatus would fulfill the limitations of Claim 2.
Claims 11 and 18 is rejected under 35 U.S.C. 103 as being unpatentable over United States Patent Application No. 2015/0159272 to Yoon et al in view of United States Patent Application No. 2018/0272390 to Ulloa and United States Patent Application No. 2016/0348240 to Burrows et al, and in further view of United States Patent Application No. 2009/0004405 to Merry et al and United States Patent Application No. 2007/0095289 to Arami et al.
The teachings of Yoon in view of Ulloa and Burrows are relied upon as set forth in the above 103 rejection of Claim 1.
In regards to Claims 11 and 18, Yoon in view of Ulloa and Burrows do not expressly teach the inner liner comprises material selected from clear quartz and silicon-carbide (SiC) coated graphite, the top plate and the bottom plate comprise material selected from clear quartz, opaque quarts, silicon-carbide (SiC) coated graphite, the first ring reflector comprises material selected from opaque quartz or silicon- carbide (SiC) coated graphite, and the plurality of shelves comprises silicon-carbide (SiC) coated graphite.
Burrows teaches an inner liner 202 Fig. 2A, 2B can be made of SiC coated graphite [0021].
It has been held that the selection of a known material based on its suitability for its intended use supports a prima facie obviousness determination. See MPEP 2144.07. Sinclair & Carroll Co. v. Interchemical Corp., 325 U.S. 327, 65 USPQ 297 (1945). Therefore, because it is known to make an inner liner analogous to that of Yoon in view of Ulloa out of SiC coated graphite, as taught by Burrows, it would be prima facie obvious to one of ordinary skill in the art at the time of the invention to do so.
Merry teaches a cassette/boat/susceptor 168 Fig. 1 can be made out of silicon coated graphite [0034] such that the top and bottom plates are made out of SiC coated graphite as are the shelves.
It has been held that the selection of a known material based on its suitability for its intended use supports a prima facie obviousness determination. See MPEP 2144.07. Sinclair & Carroll Co. v. Interchemical Corp., 325 U.S. 327, 65 USPQ 297 (1945). Therefore, because it is known to make a cassette analogous to that of Yoon in view of Ulloa out of SiC coated graphite, as taught by Merry, it would be prima facie obvious to one of ordinary skill in the art at the time of the invention to do so.
Arami teaches a reflector plate 102 Fig. 6, 7 can be made of opaque quartz [0064].
It has been held that the selection of a known material based on its suitability for its intended use supports a prima facie obviousness determination. See MPEP 2144.07. Sinclair & Carroll Co. v. Interchemical Corp., 325 U.S. 327, 65 USPQ 297 (1945). Therefore, because it is known to make a reflector analogous to that of Yoon in view of Ulloa out of opaque quartz, as taught by Arami, it would be prima facie obvious to one of ordinary skill in the art at the time of the invention to do so.
The resulting apparatus fulfills the limitations of the claim.
