Office Action

§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 . Information Disclosure Statement The information disclosure statement (IDS) submitted on 6/5/2024 was filed before the mailing date of the Non final rejection on 9/4/2026. The submission is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. Drawings The formal drawings filed on 6/5/2024 have been approved by the examiner. Specification Applicant is reminded of the proper content of an abstract of the disclosure. A patent abstract is a concise statement of the technical disclosure of the patent and should include that which is new in the art to which the invention pertains. The abstract should not refer to purported merits or speculative applications of the invention and should not compare the invention with the prior art. If the patent is of a basic nature, the entire technical disclosure may be new in the art, and the abstract should be directed to the entire disclosure. If the patent is in the nature of an improvement in an old apparatus, process, product, or composition, the abstract should include the technical disclosure of the improvement. The abstract should also mention by way of example any preferred modifications or alternatives. Where applicable, the abstract should include the following: (1) if a machine or apparatus, its organization and operation; (2) if an article, its method of making; (3) if a chemical compound, its identity and use; (4) if a mixture, its ingredients; (5) if a process, the steps. Extensive mechanical and design details of an apparatus should not be included in the abstract. The abstract should be in narrative form and generally limited to a single paragraph within the range of 50 to 150 words in length. See MPEP § 608.01(b) for guidelines for the preparation of patent abstracts. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. In claim 2, the phrase “ the gate cut dielectric pillar has a height the is greater than a height of the dielectric pillar structure ” is vague and indefinite since the paragraph 46 of the specification recites the cut dielectric pillar has a height the is less than a height of the dielectric pillar structure. Also, Figs. 6A and 6B show the same dimension as paragraph 46 of the specification. Allowable Subject Matter Claims 1 and 3-20 are allowed. 8. The following is a statement of reasons for the indication of allowance subject matter: none of the prior art of record teaches or suggest the combination of a backside back-end-of-the-line (BEOL) structure 66 electrically connected to a first source/drain region of a first transistor of the pair of transistors by a backside source/drain contact structure. The first source/drain region wraps around an upper portion of the backside source/drain contact structure, and the backside source/drain contact structure is located entirely beneath the gate structure of the pair of transistors in claims 1 and 11. Conclusion 9. Any inquiry concerning the communication or earlier communications from the examiner should be directed to Alonzo Chambliss whose telephone number is (571) 272-1927. If attempts to reach the examiner by telephone are unsuccessful, the examiner's supervisor, Jacob Y. Choi can be reached on (469) 295-9060.
