(see Paragraph [0012]) Response to Arguments 07-37 AIA Applicant's arguments filed 05/04/2026 have been fully considered but they are not persuasive. Based on the new amendments, Examiner has amended the interpretation to contain a portion of the ILD 256 to be a portion of the dielectric liner, which meets the limitations of at least claims 1, 6, 11, and 16. It should be noted that since the ILD layers can be made using CVD, (See at least paragraph [0014]) a proper interpretation can be made to split the layer 256 into multiple layers, and to have multiple layers considered one “layer.” Therefore, claims 1, 6, 11, and 16 are rejected, and claims 2-5, 7-10, 12-15, and 17-20 are rejected for at least their dependencies . Conclusion 07-96 AIA The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Bi et al. (US 20200287039 A1) – semiconductor nanowires in a gate structure Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL . See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
