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 .
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.
Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
Claims 14, 26, 28, and 30-32 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Haukka et al, US 2015/0217330 A1.
Haukka et al teaches:
Regarding claim 14, a substrate processing method comprising: a catalyst component supplying process of supplying a catalyst component, which is to be adsorbed on a substrate, to the substrate; a film-forming component supplying process of supplying a film-forming component, which forms an insulating film on the substrate in the presence of the catalyst component, to the substrate (Paragraph 0309); and an inhibition component supplying process of supplying an inhibition component, which is to be adsorbed on the substrate and inhibits adsorption of the catalyst component on the substrate, to a front surface or a back surface of the substrate (Paragraph 0032), wherein the inhibition component supplying process is performed before the catalyst component supplying process (step 520).
Regarding claim 26, the film-forming component is an aminosilane (Step 530) which is an organic silane compound.
Regarding claim 28, the catalyst component is a metal compound. (Paragraph 0309)
Regarding claim 30, the catalyst component supplying process and the film-forming component supplying process are repeated. (Figure 5, Paragraph 0309)
Regarding claim 31, the inhibition component is an organic silane compound, which forms a self-assembled monolayer on the substrate. (Paragraph 0030-0032)
Regarding claim 32, the inhibition component supplying process, the catalyst component supplying process, and the film-forming component supplying process are repeated each time the process of Figure 5 is conducted.
Claim Rejections - 35 USC § 103
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.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claims 15 and 16 are rejected under 35 U.S.C. 103 as being unpatentable over Haukka et al, US 2015/0217330 A1, in view of JP2019-532336 A (‘336).
Regarding claim 15:
Haukka et al was discussed above.
Haukka et al differs from the present invention in that Haukka et al does not teach that the inhibition component is supplied only to the back surface of the substrate.
‘336 teaches supplying the inhibition component to the back surface of the substrate.
The motivation for supplying the inhibition component to the back surface of the substrate of Haukka et al is to improve the holding ability of the chuck as taught by ‘336 or to prevent deposition on the backside of the substrate as is well known in the art.
Therefore it would have been obvious to one of ordinary skill in the art before the time the invention was effectively filed to supply the inhibition component to the back surface of the substrate of Haukka et al as taught by ‘336 and well known in the art.
Regarding claim 16, Haukka et al teaches that the film-forming component is an aminosilane (Step 530) which is an organic silane compound.
Claims 17 and 18 are rejected under 35 U.S.C. 103 as being unpatentable over Haukka et al and ‘336 as applied to claims 15 and 16 above, and further in view of Mizoguchi et al, US 20220005693 A1.
Regarding claim 17:
Haukka et al and ‘336 differ from the present invention in that they do not teach that the organic silane compound is tris(tert-pentoxy)silanol or tris(tert-butoxy)silanol.
Mizoguchi et al teaches using tris(tert-pentoxy)silanol in an ald process. (Paragraph 0045)
The motivation for replacing the aminosilane of Haukka et al and ‘336 with tris(tert-pentoxy)silanol as taught by Mizoguchi et al is to provide an alternate silane source. Furthermore, it has been held that the simple substitution of one known element for another to obtain predictable results is obvious (see KSR International Co. v. Teleflex Inc.).
Therefore it would have been obvious to one of ordinary skill in the art before the time the invention was effectively filed to replace the aminosilane of Haukka et al and ‘336 with tris(tert-pentoxy)silanol as taught by Mizoguchi et al.
Regarding claim 18, Haukka et al teaches that the catalyst component is a metal compound.
Claims 19-23 are rejected under 35 U.S.C. 103 as being unpatentable over Haukka et al, ‘336, and Mizoguchi et al, as applied to claims 15-18 above, and further in view of Illobero et al, US 20210301394 A1.
Regarding claim 19:
Haukka et al, ‘336, and Mizoguchi et al differ from the present invention in that they do not teach that the metal compound is trimethylaluminum or trimethylgallium.
Illobero et al teaches using trimethylaluminum (TMA) as a metal catalyst. (Paragraph 0007)
The motivation for replacing the metal catalyst (Hf(Net2)4) of Haukka et al, ‘336, and Mizoguchi et al with trimethylaluminum (TMA) as taught by Illobero et al is to provide an alternate metal catalyst. Furthermore, it has been held that the simple substitution of one known element for another to obtain predictable results is obvious (see KSR International Co. v. Teleflex Inc.).
Therefore it would have been obvious to one of ordinary skill in the art before the time the invention was effectively filed to replace the metal catalyst (Hf(Net2)4) of Haukka et al, ‘336 and Mizoguchi et al with trimethylaluminum (TMA) as taught by Illobero et al.
Regarding claim 20, Haukka et al teaches the catalyst component supplying process and the film-forming component supplying process are repeated. (Figure 5)
Regarding claim 21, Haukka et al teaches that the inhibition component is an organic silane compound, which forms a self-assembled monolayer on the substrate. (Paragraph 0030-0032)
Regarding claim 22, Haukka et al teaches that the inhibition component supplying process, the catalyst component supplying process, and the film-forming component supplying process are repeated each time the process of Figure 5 is conducted.
Regarding claim 23, ‘336 teaches removing the inhibition component adsorbed on the substrate, wherein the removing process is performed after the film-forming component supplying process. (Figure 13, Paragraph 0076)
Claims 24 and 25 are rejected under 35 U.S.C. 103 as being unpatentable over Haukka et al, ‘336, Mizoguchi et al, and Illobero et al as applied to claims 15-23 above, and further in view of Gadda et al, US 20210311394 A1.
Regarding claim 24:
Haukka et al, ‘336, Mizoguchi et al, and Illobero et al differ from the present invention in that they do not teach that the removing process, plasma of an oxygen-containing gas is supplied to the substrate.
Gadda et al teaches a removing process using an oxygen plasma. (Paragraph 0202
The motivation for using an oxygen plasma in the method of Haukka et al, ‘336, Mizoguchi et al, and Illobero et al is to provide an alternate method of removing the inhibition component as taught by Gadda et al. Furthermore, it has been held that the simple substitution of one known element for another to obtain predictable results is obvious (see KSR International Co. v. Teleflex Inc.).
Therefore it would have been obvious to one of ordinary skill in the art before the time the invention was effectively filed to add an oxygen plasma method of Gadda et al to the removing process method of Haukka et al, ‘336, Mizoguchi et al, and Illobero et al.
Regarding claim 25, Haukka et al, ‘336, Mizoguchi et al, Illobero et al, and Gadda et al differ from the present invention in that they do not teach that in the removing process, H2, NH3, plasmarized H2 or NH3, or a hydrazine-containing gas is supplied to the substrate. The Examiner notes that H2, NH3, plasmarized H2 or NH3, or a hydrazine-containing gas are all well known in the art as cleaning gases commonly used to remove material from a substrate. Therefore it would have been obvious to one of ordinary skill in the art before the time the invention was effectively filed to supply H2, NH3, plasmarized H2 or NH3, or a hydrazine-containing gas to the substrate in the removing process method of Haukka et al, ‘336, Mizoguchi et al, Illobero et al, and Gadda et al.
Claims 27 and 33 are rejected under 35 U.S.C. 103 as being unpatentable over Haukka et al, US 2015/0217330 A1, in view of Mizoguchi et al, US 20220005693 A1.
Regarding claim 27:
Haukka et al was discussed above.
Haukka et al differs from the present invention in that Haukka et al does not teach that the organic silane compound is tris(tert-pentoxy)silanol or tris(tert-butoxy)silanol.
Mizoguchi et al teaches using tris(tert-pentoxy)silanol in an ald process.
The motivation for replacing the aminosilane of Haukka et al with tris(tert-pentoxy)silanol as taught by Mizoguchi et al is to provide an alternate silane source. Furthermore, it has been held that the simple substitution of one known element for another to obtain predictable results is obvious (see KSR International Co. v. Teleflex Inc.).
Therefore it would have been obvious to one of ordinary skill in the art before the time the invention was effectively filed to replace the aminosilane of Haukka et al with tris(tert-pentoxy)silanol as taught by Mizoguchi et al.
Regarding claim 33:
Haukka et al was discussed above.
Haukka et al differs from the present invention in that Haukka et al does not teach a controller programed to control the claimed method.
Mizoguchi et al teaches using a controller 26 to control a method.
The motivation for programing the controller of Mizoguchi et al with the method of Haukka et al is to enable the apparatus of Mizoguchi et al to execute the method of Haukka et al.
Therefore it would have been obvious to one of ordinary skill in the art before the time the invention was effectively filed to program the controller of Mizoguchi et al with the method of Haukka et al.
Claim 29 is rejected under 35 U.S.C. 103 as being unpatentable over Haukka et al, US 2015/0217330 A1, in view of Illobero et al, US 20210301394 A1.
Haukka et al was discussed above.
Haukka et al differs from the present invention in that Haukka et al does not teach that the metal compound is trimethylaluminum or trimethylgallium.
Illobero et al teaches using trimethylaluminum (TMA) as a metal catalyst. (Paragraph 0007)
