Office Action

§103
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 Applicant’s election without traverse of Invention I, Species 1 (claims 1-5, 7-10, and 18-20) in the reply filed on is acknowledged. Claims 6 and 11-17 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected invention, there being no allowable generic or linking claim. 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: a plasma source in claims 1 and 7 a holding member in claims 1-3 and 18 a gas supply unit in claims 7 and 18 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. Paragraphs [0074], [0086]-[0087] of the specification indicates the plasma source is the chuck 210, top edge electrode 510, bottom edge electrode 250. Paragraphs [0083]-[0084] of the specification indicates the holding member 240 is a ceramic shaped insert that varies in shape depending on the grooves’ shape. Paragraphs [0096]-[0097] and [0099] of the specification indicates a gas supply unit 700 includes a first gas supply unit 720 and second gas supply unit 740. Each gas supply unit includes a gas supply source, a gas supply line, and a valve. 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 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. 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. Claim(s) 1-5, 7-10, and 18-20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Ji (KR102235339B1) in view of Park et al. (KR20110077575A) and . Referring to Figure 2 and paragraphs [0041]-[0057], Ji disclose a substrate treating apparatus comprising: a housing 100 having a treating space (pars.[0043]-[0044]); a support unit 300 configured to support a substate within the treating space (par.[0045]); and a plasma source 310, 350, 620 for generating a plasma by exciting a gas supplied to the treating space (pars.[0047]-[0049]), and wherein the support unit 300 includes: a chuck 310 having the substrate mounted to a top surface thereof; and a ring member 330 in a ring shape surrounding an outer side of the chuck (par.[0045], [0048]) Ji is silent on a ring member that includes a cut surface which divides the ring member and a holding member positioned at the cut surface which holds a position of the ring member which is divided by the cut surface. Referring to Figures 2-3, abstract, and page 3, Park et al. teach a substrate treating apparatus wherein a ring member 30 that includes a cut surface which divides the ring member 34, 36 and a holding member 37 positioned at the cut surface which holds a position of the ring member which is divided by the cut surface since it is used to promote plasma uniformity. Additionally, referring to Figures 1-2 and abstract, Shimada teach a substrate treating apparatus wherein a holding member 31 is used between ring members in order to improve the air tightness between the ring members. Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to have modified the apparatus of Ji with a ring member that includes a cut surface which divides the ring member and a holding member positioned at the cut surface which holds a position of the ring member which is divided by the cut surface as taught by Park et al. and Shimada since it would promote plasma uniformity and provide airtightness at the cut surface. The resulting apparatus of Ji in view of Park et al. would yield a ring member that includes a cut surface which divides the ring member and a holding member positioned at the cut surface which holds a position of the ring member which is divided by the cut surface. With respect to claim 2, the substrate treating apparatus of Ji in view of Park et al. further includes wherein a groove at which the holding member 37 is inserted is formed at the ring member 34 (Park et al.-Fig. 3). With respect to claim 3, the substrate treating apparatus of Ji in view of Park et al. further includes wherein the groove is formed at an inner side of the ring member, and a top end of the groove is positioned lower than a top end of the ring member 34, and a bottom end of the groove is positioned higher than a bottom end of the ring member (Park et al.-Fig. 3). With respect to claim 4, the substrate treating apparatus of Ji in view of Park et al. further includes wherein the ring member 34 is divided with respect to the cut surface, and the holding member 37 is inserted in the groove to limit a movement in a lengthwise direction of each divided ring member (Park et al.-Fig. 3). With respect to claim 5, the substrate treating apparatus of Ji in view of Park et al. further includes wherein the cut surface is formed in a horizontal direction to the cut surface of the ring member 34, 36 (Park et al.-Fig. 3). . With respect to claim 7, the substrate treating apparatus of Ji in view of Park et al. further comprising: a dielectric plate 500 positioned to face a top surface of the substrate supported on the support unit 300 (par.[0052]); and a gas supply unit 700 configured to supply a gas to an edge region of the substrate (par.[0055]), and wherein the plasma source includes: a top edge electrode 620 positioned above the edge region; and a bottom edge 350 electrode positioned below the edge region (Ji-par.[0053]). With respect to claim 8, the substrate treating apparatus of Ji in view of Park et al. further includes wherein the bottom edge electrode 350 is formed in a ring shape, and surrounds an outer side of the ring member 330 (Ji-par.[0049]). With respect to claim 9, the substrate treating apparatus of Ji in view of Park et al. further includes wherein the chuck 310 and the ring member 330 share a same center, and an inner side of the ring member contacts the outer side of the chuck (Ji-Figure 2). With respect to claim 10, the substrate treating apparatus of Ji in view of Park et al. further includes wherein the chuck and the ring member have a different thermal expansion rate from one another (i.e. chuck-conductor, ring member-insulator, Ji-par.[0048])). With respect to claim 18, referring to Figure 2 and paragraphs [0041]-[0057], Ji disclose a substrate treating apparatus comprising: a housing 100 having a treating space (pars.[0043]-[0044]); a support unit 300 configured to support a substate within the treating space (par.[0045]); a dielectric plate positioned to face a top surface of a substrate supported on the support unit; a dielectric plate 500 positioned to face a top surface of the substrate supported on the support unit 300 (par.[0052]); and a gas supply unit 700 configured to supply a gas to an edge region of the substrate (par.[0055]), and wherein the support unit 300 includes: a chuck 310 having the substrate mounted to a top surface thereof; and a ring member 330 in a ring shape surrounding an outer side of the chuck (par.[0045], [0048]). Ji is silent on the ring member includes: a cut surface which divides the ring member; a groove which is formed at a position corresponding to the cut surface; and a holding member inserted in the groove to limit a movement in a lengthwise direction of the ring member which is divided by the cut surface. Referring to Figures 2-3, abstract, and page 3, Park et al. teach a substrate treating apparatus the ring member 30 includes: a cut surface which divides the ring member 34, 36; a groove which is formed at a position corresponding to the cut surface; and a holding member 37 inserted in the groove to limit a movement in a lengthwise direction of the ring member which is divided by the cut surface since it is used to promote plasma uniformity. Additionally, referring to Figures 1-2 and abstract, Shimada teach a substrate treating apparatus wherein a holding member 31 is used between ring members in order to improve the air tightness between the ring members. Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to have modified the apparatus of Ji with the ring member includes: a cut surface which divides the ring member; a groove which is formed at a position corresponding to the cut surface; and a holding member inserted in the groove to limit a movement in a lengthwise direction of the ring member which is divided by the cut surface as taught by Park et al. and Shimada since it would promote plasma uniformity and provide airtightness at the cut surface. The resulting apparatus of Ji in view of Park et al. would yield the ring member includes: a cut surface which divides the ring member; a groove which is formed at a position corresponding to the cut surface; and a holding member inserted in the groove to limit a movement in a lengthwise direction of the ring member which is divided by the cut surface. With respect to claim 19, the substrate treating apparatus of Ji in view of Park et al. further includes wherein the chuck 310 and the ring member 330 share a same center, and an inner side of the ring member contacts the outer side of the chuck (Ji-Fig. 2) and the groove is formed at the inner side between a top end of the ring member 34 and a bottom end of the ring member 34 (Park et al.-Fig. 3). With respect to claim 20, the substrate treating apparatus of Ji in view of Park et al. further includes wherein the chuck and the ring member have a different thermal expansion rate from one another (i.e. chuck-conductor, ring member-insulator, Ji-par.[0048])).
