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 .
Specification
The disclosure is objected to because of the following informalities: At the first page, in the preliminary amendment to the specification of dated 3/25/2024, the continuing date needs to be updated, such as the application No. 17/415,104 is now US patent 11,993,849.
Appropriate correction is required.
The abstract of the disclosure is objected to because at the end of the abstract, there is a phrase “[Representative Figure] Fig.7” needs to be deleted from the abstract. A corrected abstract of the disclosure is required and must be presented on a separate sheet, apart from any other text. See MPEP § 608.01(b).
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.
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 is/are rejected under 35 U.S.C. 103 as being unpatentable over Won et al (US 212/0276743) in view of Ito et al (US 2015/0030792).
Regarding claim 1, Won et al disclose a hard mask layer including a diamond-like carbon, etching the hard mask layer to form a hard mask layer pattern, and etching the insulation layer to form an insulation layer pattern using the hard mask layer pattern as an etching mask ([0011]; Figures 6-9), wherein the hard mask layer (220) is laminated on an etching target film (210) [0076].
Won et al also disclose that the carbon-containing hard mask 220 layer is formed by a deposition process using the ICP deposition apparatus illustrated in FIG. 1, for example, by an ICP-PECVD process. A process gas for generating a plasma may include helium gas or argon gas. A reactive gas that may be activated by a collision with the plasma to form the hard mask layer 220 on the insulation layer 210 may include a hydrocarbon compound gas including, e.g., C.sub.3H.sub.6, C.sub.4H.sub.8 or C.sub.6H.sub.12 [0079].
Unlike the instant invention, Won et al fail to disclose the deposited hard mask layer having a concentration ratio of methylene group (CH2) and a methyl group (CH3) satisfies the claimed equation as recited in claim 1.
However, Ito et al disclose a hydrocarbon film is vapor-deposited on the surface of a base material, and includes two layers of a high CH.sub.2 layer having a ratio of CH.sub.2 per the total of CH, CH.sub.2 and CH.sub.3 of not less than 40% [0015]; and aforesaid teaching appears to overlaps the claimed range as expressed in the equation 1.
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to employ Ito et al's teaching of depositing the hydrocarbon layer with the configuration of a carbon film that contain more CH2 than CH3 into the teaching of Won et al for achieving a hard mask layer suggested by Ito et al and additionally, such better etching selectivity than amorphous carbon layer as required in the Won et al ([0076] in Won et al).
Conclusion
The prior art made of record, listed in the PTO-892 and not relied upon is considered pertinent to applicant's disclosure. Osawa et al (US 4913,994) disclose an amorphous material comprising hydrogen and carbon atoms, said carbon atoms constituting methyl group and methylene group in a ratio of the former to the latter being 0.5:1 to 3:1 (col.8, lines 7-9).
