DETAILED ACTION
Election/Restrictions
Applicant's election with traverse of Group 1 (claims 1-16) in the reply filed on July 6, 2026 is acknowledged. The traversal is on the grounds that “examination of all of the identified inventions and all of the pending claims would not result in a serious search and/or examination burden”. This is not found persuasive because the restriction requirement clearly outlined a lack of unity, with a reference. Also, search burden is not a consideration in Unity of Invention analysis. The requirement is still deemed proper and is therefore made FINAL.
Priority
Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55.
Information Disclosure Statement
The references cited within the IDS documents have been considered.
IDS document dates: December 4, 2023; December 6, 2023; January 8, 2026.
Drawings
The drawings are objected to because of informalities as follows:
37 CFR 1.84(g) states, in part: “Margins. The sheets must not contain frames around the sight (i.e., the usable surface), but should have scan target points (i.e., cross-hairs) printed on two catercorner margin corners.”
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.
Claim Rejections - 35 USC § 102
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.
Claims 1, 8, 12, and 16 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Fukuoka (US 2018/0033816 A1).
As to claim 1, Fukuoka teaches (in figures 1 and 6) a semiconductor device comprising:
a photoelectric converting section (112) that generates a charge according to a received light amount; and
a transfer transistor (120) that transfers the charge of the photoelectric converting section to a predetermined charge accumulation section, wherein
the transfer transistor has a vertical gate electrode (123) including an embedded electrode part embedded in a semiconductor substrate (111), and
the embedded electrode part includes an embedded upper electrode and an embedded lower electrode that is arranged on a substrate deep-portion side relative to the embedded upper electrode and that is formed to have an electrode area size, in a plan view, greater than an electrode area size of the embedded upper electrode (see annotated figure below).

As to claim 8, Fukuoka teaches a predetermined charge accumulation section (i.e. a floating diffusion region, 124) includes a high concentration impurity region (n+).
As to claim 12, Fukuoka teaches the semiconductor device includes a solid-state imaging element, and each pixel of the solid-state imaging element includes the photo-electric converting section and the transfer transistor. See figure 1.
As to claim 16, Fukuoka teaches a planar shape of the embedded lower electrode is a polygon.
(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.
Claims 1, 2, 12, and 16 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Chen et al. (US 2023/0079156, hereinafter referred to as ‘Chen’).
As to claim 1, Chen teaches (in figures 4, 5, and 9) a semiconductor device comprising:
a photoelectric converting section (441) that generates a charge according to a received light amount; and
a transfer transistor (942) that transfers the charge of the photoelectric converting section to a predetermined charge accumulation section, wherein
the transfer transistor has a vertical gate electrode (942) including an embedded electrode part embedded in a semiconductor substrate (410), and
the embedded electrode part includes an embedded upper electrode and an embedded lower electrode that is arranged on a substrate deep-portion side relative to the embedded upper electrode and that is formed to have an electrode area size, in a plan view, greater than an electrode area size of the embedded upper electrode (see figures 5 and 9).
As to claim 2, Chen teaches the embedded lower electrode is formed as a rectangular tube (see figures 4, 5, and 9).
As to claim 12, Chen teaches the semiconductor device includes a solid-state imaging element, and each pixel of the solid-state imaging element includes the photo-electric converting section and the transfer transistor. See figure 4.
As to claim 16, Chen teaches a planar shape of the embedded lower electrode is a polygon. See figures 5 and 9.
Allowable Subject Matter
Claims 3-7, 9-11, 13, and 15 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. (Claim 14 is also objected to as being dependent upon an objected claim.)
