Office Action

§103 §112
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 . The response of the applicant has been read and given careful consideration. Rejection of the previous action not repeated below are withdrawn in view of the arguments and amendment of the applicant. Responses to the arguments of the applicant are presented after the first rejection to which they are directed. The amendment filed 07/06/2026 is objected to under 35 U.S.C. 132(a) because it introduces new matter into the disclosure. 35 U.S.C. 132(a) states that no amendment shall introduce new matter into the disclosure of the invention. The added material which is not supported by the original disclosure is as follows: The text added in [0366] excluding Rl1-Rl3 not all being hydrogen at the same time and replacing “optionally having a heteroatom” with 6 lines of added text is not supported by the specification as filed. Applicant is required to cancel the new matter in the reply to this Office Action. The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claims 1-22 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. The language “may contain a hydroxy group, an alkoxy group, a thioalkoxy group, a fluorine-containing alkyl group, a fluorine-containing alkoxy group, a fluorine-containing thioalkoxy group, a cyano group, a fluorine atom, a chlorine atom, a bromine atom, an iodine atom, a carbonyl group, an ether bond, an ester bond, a sulfonic acid ester bond, a carbonate bond, a lactone ring, a sultone ring, a carboxylic anhydride, a haloalkyl group” appears in [0082] as possibilities for RL1-RL3, not RL4. 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 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. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. 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. Claim 1-6,8-10,12, and 15-22 are rejected under 35 U.S.C. 103 as being unpatentable over Hirano et al. JP 2008249890.

JP 2008249890 does not exemplify polymers where at least one of RL1-RL3 is a hydrocarbyl group The reference also does not exemplify polymers with the full range of repeating units recited in claim 6 or repeating units of claim 1 with halogen or hydrocarbyl moieties other than acetate and methyl carbonyl. With respect to claims 1-6 and 8, it would have been obvious to one skilled in the art to modify the polymer A-13 or A-2 by replacing the C1 methyl in the acetal group with a C2-19 alkyl group based upon the disclosed at disclosed that L can be a linear or branched C1-30 alkyl at [0030] with a reasonable expectation of forming a useful resist polymer. With respect to claims 1-6 and 8, it would have been obvious to one skilled in the art to modify the polymer A-13 or A-2 by replacing the C1 methyl in the acetal group with a C2-19 alkyl group based upon the disclosed at disclosed that L can be a linear or branched C1-30 alkyl at [0030] and the terminal phenyl ring is substituted with an ether (-O-),, alkoxy or thioalkoxy groups rather than an ester group based upon the disclosure at [0033-0034] with a reasonable expectation of forming a useful resist polymer. With respect to claims 1-6,8-10,12, and 15-20, it would have been obvious to one skilled in the art to modify the resist composition of example 10 by using a polymer similar to polymer A-13 where the the C1 methyl in the acetal group is replaced with a C2-19 alkyl group based upon the disclosed at disclosed that L can be a linear or branched C1-30 alkyl at [0030] with a reasonable expectation of forming a useful resist composition. With respect to claims 1-6,8-10,12, and 15-20, it would have been obvious to one skilled in the art to modify the resist composition of example 10 by using a polymer similar to polymer A-13 where the C1 methyl in the acetal group is replaced with a C2-19 alkyl group based upon the disclosed at disclosed that L can be a linear or branched C1-30 alkyl at [0030] and the terminal phenyl ring is substituted with an ether (-O-),, alkoxy or thioalkoxy groups rather than an ester group based upon the disclosure at [0033-0034] with a reasonable expectation of forming a useful resist composition. In addition to the basis above, it would have been obvious to one skilled in the art to modify the exemplified polymers of Hirano et al. JP 2008249890, resists using them or polymers/resists rendered obvious by Hirano et al. JP 2008249890 by adding a other repeating units disclosed such as those disclosed on pages 31 and 32 of Hirano et al. JP 2008249890 with a reasonable expectation of forming as useful resist based upon the disclosure of these as useful repeating units, by using other exposures, such as excimer lasers, EUV with a reasonable expectation of forming a useful pattern based upon the disclosure of these as actinic light at [0304] and/or by using other disclosed substrates such as a chromium oxide coated quartz substrate With respect to claims 15 and 16, the examiner holds that the dissolution rate of the unexposed resist is less than 10 nm/min for at least one alkaline developer composition. With respect to claim 17, the examiner holds that the dissolution rate of the exposed resist is more than 50 nm/min for at least one alkaline developer composition. In the response of 7/6/2026, the applicant argues that the claims do not disclosed/exemplify a polymer having a repeating unit bounded by the added claim language. The examiner points to PNG media_image26.png 98 170 media_image26.png Greyscale PNG media_image27.png 109 286 media_image27.png Greyscale , where the RL1-RL3 are hydrogen, and n1 is 1, and RL4 is an ester, which also includes a -O- bond and L can be C2-19 alkyl which is within the C1-30 range disclosed at [0030]. Claims 1-6,8-10,12 and 15-20 are rejected under 35 U.S.C. 103 as being unpatentable over Mizutani JP 2005274878.

A resist film was obtained in the same manner as in Example 1 using the resist compositions in Examples 1 and 2 and Comparative Examples 1 and 2. However, the resist film thickness was 0.15 μm. The obtained resist film was subjected to surface exposure using EUV light (wavelength 13 nm) while changing the exposure amount by 0.5 mJ in the range of 0 to 5.0 mJ, and further baked at 110 ° C. for 90 seconds. Thereafter, using a 2.38 mass% tetramethylammonium hydroxide (TMAH) aqueous solution, the dissolution rate at each exposure amount was measured to determine the sensitivity [0195].
