Office Action

§112
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 . Status of Claims Claims 17-18,20-25,27-35 and 39-41 pending. Claims 17, 18, 20, 29-35, 39, and 41 allowable. Claims 21-25 and 27-28, 40 are rejected. Drawings The drawings are objected to under 37 CFR 1.83(a). The drawings must show every feature of the invention specified in the claims. Therefore, the LDD region comprises a portion directly under the source line gate, the portion of the LDD region interfaces the first implant region in claim 21 must be shown or the feature(s) canceled from the claim(s). No new matter should be entered. Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. Specification The specification is objected to as failing to provide proper antecedent basis for the claimed subject matter. See 37 CFR 1.75(d)(1) and MPEP § 608.01(o). Correction of the following is required: Regarding claim 21. Claim 21 recites the limitation “the LDD region comprises a portion directly under the source line gate, the portion of the LDD region interfaces the first implant region” in the claim language. Claim Rejections - 35 USC § 112 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 21-25, 27, 28 and 40 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. Regarding claim 21. Claim 21 recites the limitation “the LDD region comprises a portion directly under the source line gate, the portion of the LDD region interfaces the first implant region” in the claim language. Applicant does not have written support for the portion of the interfaces the first implant region when the LDD region comprises a portion directly under the source line gate. Claims 22-25, 27, 28 and 40 are rejected for dependence upon a 112(a) rejected instance claim. 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. Claims 21-25, 27, 28, and 40 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Regarding claim 21. Claim 21 recites the limitation “the LDD region comprises a portion directly under the source line gate, the portion of the LDD region interfaces the first implant region” in the claim language. It is unclear to the examiner as to how the portion of the LDD region interfaces the first implant region. The claim language requires the LDD region comprises a portion directly under the source line gate, forming an oxidized region on the second implant region, forming a source line gate over the convex upper surface of the oxide region. It would appear to the examiner that the portion would interface the second implant region based upon the prior claim language, not the first implant region as the amended claim language states. Examiner recommends applicant amends the last line of the claim language from “LDD region interfaces the first implant region” to read “LDD region interfaces the second implant region” to overcome this rejection. Allowable Subject Matter Claims 17, 18, 20, 29-35, 39, and 41 allowed. Response to Arguments Applicant's arguments filed March 23, 2026 have been fully considered but they are not persuasive. On page 10 of applicant’s remarks applicant appears to argue that the prior art of record does not have the amended claim language of the LDD region comprises a portion directly under the source line gate, the portion of the LDD region interfaces the first implant region. Examiner respectfully points out that applicant does not have support for the amended claim language as cited above. Examiner respectfully recommends applicant amends the last line of the claim language from “LDD region interfaces the first implant region” to read “LDD region interfaces the second implant region” to obviate drawing, specification objections, the 112 rejections, and to put claim 21 in condition for allowance. Conclusion 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.
