DETAILED ACTION
This correspondence is in response to the communications received 07/01/2026. Claims 1, 2, 4, 5, 9, 11, 17, 19, and 20 have been amended. Claims 1-20 are pending.
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 08/04/2026 has been considered by the examiner and made of record in the application file.
Response to Amendment
Applicant’s amendment to claim 20 overcomes the objection outlined in the previous Office Action. The objection is withdrawn.
Applicant’s amendment to claim 5 overcomes the 112(b) rejection outlined in the previous Office Action. The rejection is withdrawn.
Response to Arguments
Applicant's arguments with respect to claims 1, 7, 9, and 17 on pages 11-13 in the Remarks filed 07/01/2026 have been fully considered but they are not persuasive.
Applicant argues that Noudo (US 11,387,265 B2) in combination with Zhou et al. (US 11,296,249 B2), Kusunoki et al. (US 20240381702 A1), and Liu et al. (US 9,379,072 B2) fails to disclose or otherwise suggest all the claim limitations of claims 1 and 9. Specifically that Kusunoki does not disclose an adhesive layer with a bent portion with an inclination of a second angle α2 at the boundary P1. Applicant’s argument appears to rely on the placement of the second angle α2 as being at the boundary P1, however this language is not present in the claims. Instead, claim 1 requires “wherein the adhesive layer includes a bent portion having an inclination of a second angle relative to a boundary. Thus, the second angle need only be defined relative to the boundary, not necessarily placed at the boundary. As seen in Fig. 2B of Kusunoki below, the second angle of “an insulating layer 105”, [0107], relative to the vertical boundary formed between the inclined area and first flat area of “conductive layer 104”, [0107], is equal to the first angle of the slope of the inclined area of 104 relative to the same vertical boundary.

Furthermore, as 105 is disposed directly on 104, the second angle of the bent portion of 105 will necessarily be equal to the angle of the inclined area of 104 regardless of the frame of reference. Therefore, the rejections of claims 1 and 9 are maintained.
In addition, Applicant argues that Noudo (US 11,387,265 B2) in combination with Zhou et al. (US 11,296,249 B2), Hsu et al. (US 9,437,578 B2), Kusunoki et al. (US 20240381702 A1), and Liu et al. (US 9,379,072 B2) fails to disclose or otherwise suggest all the claim limitations of claim 17. Specifically, that Kusunoki does not disclose “wherein the adhesive layer includes:
a first extension extending along the top face of the passivation layer and in the first direction;
a bent portion disposed on the inclined area of the conductive pattern and extending along the conductive pattern, wherein the bent portion is bent from the first extension; and
a second extension disposed on the first flat area of the conductive pattern and extending in the first direction, wherein the second extension is connected to the bent portion, and
wherein the boundary between a top face of the conductive pattern in the inclined area and a top face of the conductive pattern in the first flat area is the same as the boundary between the top face of the adhesive layer in the bent portion and a top face of the adhesive layer in the second extension.” However, as discussed in the rejection of claim 19 in the previous Office Action, Kusunoki discloses the first and second extensions and the bent portion. In addition, as the newly required boundaries are defined as an intersection between faces, each boundary therefore only needs to pass through the vertex between the corresponding faces, thus a single line can be drawn that represents a boundary between both pairs of faces. Such a line can be seen in Fig. 2BC17B below, labeled as “BD”. As seen in Fig. 2BC17B, BD is a boundary between the top faces of “conductive layer 104”, [0107], in both the inclined area and the first flat area as well as between the top faces of the adhesive layer “insulating layer 105”, [0107], in both the bent portion labeled “BP” and the second extension labeled “SE”. Therefore, the rejection of claim 17 is maintained.

In addition, Applicant argues that Noudo (US 11,387,265 B2) in combination with Zhou et al. (US 11,296,249 B2), Kusunoki et al. (US 20240381702 A1), and Liu et al. (US 9,379,072 B2) fails to disclose or otherwise suggest all the claim limitations of claim 7. Specifically, that Kusunoki does not disclose “wherein a first thickness of the first portion based on the second top face is equal to a second thickness of the second portion based on the first top face”. However, as presented in the previous Office Action the thickness of the adhesive layer “insulating layer 105”, [0107], appears to be consistent with regards to the thickness when viewed in a direction normal to the underlying layers, therefore the thickness of any one portion will be equal to that of any other portion. Further, as seen in Fig. 2B of Kusunoki, 105 appears to be conformally deposited indicating that the thickness will be consistent across the entirety of the film, and Kusunoki does not provide any suggestion to the contrary. Therefore, the rejection of claim 7 is maintained.
In addition, Applicant argues that Noudo (US 11,387,265 B2) in combination with Zhou et al. (US 11,296,249 B2), Kusunoki et al. (US 20240381702 A1), and Liu et al. (US 9,379,072 B2) fails to disclose or otherwise suggest all the claim limitations of claim 13. Specifically, that Kusunoki does not disclose “a bent portion disposed on the inclined area of the conductive pattern and extending along the conductive pattern, wherein the bent portion is bent from the first extension” and “wherein the bent portion has a constant slope relative to each of the first extension and the second extension”. However as discussed in the previous Office Action, “BP” in Fig. 2BC13 is a bent portion of the adhesive layer “insulating layer 105”, [0107], that is on the inclined area of “conductive layer 104”, [0107]. Further, as seen in Figs. 2B and 2BC13, the upper and lower surfaces of 105 in BP appear to be parallel, and thus have a constant slope relative to any other element including the first and second extensions of 105, labeled “E1” and “E2” in Fig. 2BC13. Therefore, the rejection of claim 13 is maintained.
Specification
The lengthy specification has not been checked to the extent necessary to determine the presence of all possible minor errors. Applicant’s cooperation is requested in correcting any errors of which applicant may become aware in the specification.
Claim Interpretation
Line 5 of claim 1 recites the phrase “an adhesive layer deposited on the passivation layer and the conductive pattern”. The word “deposited” does not seem to be defined or elaborated on in the specification or the claims. The word “disposed” which would in this context otherwise be considered to be synonymous with “deposited”, appears several times in claim 1, indicating a distinction between “disposed” and “deposited”. For this reason, “deposited” will be interpretated as “disposed directly on” for the purposes of this examination.
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.
Claims 17-20 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.
Claim 17 recites the limitation "the boundary between a top face of the conductive pattern in the inclined area and a top face of the conductive pattern in the first flat area" in lines 26 and 27. There is insufficient antecedent basis for this limitation in the claim. Claims 18-20 are rejected for their dependence on claim 17.
Claim 17 recites the limitation "the boundary between the top face of the adhesive layer in the bent portion and a top face of the adhesive layer in the second extension" in lines 28 and 29. There is insufficient antecedent basis for this limitation in the claim. Claims 18-20 are rejected for their dependence on claim 17.

Regarding claim 1, Fig. 3 of Noudo discloses an image sensor (“pixel array section 10”, col. 6, line 39) comprising:
a substrate (“semiconductor substrate 141”, col. 8, line 12) having a photoelectric conversion element (“photoelectric conversion section 101”, col. 8, line 16) disposed therein (as seen in Fig. 3, 141 has 101 disposed therein);

However, in a similar field of endeavor, Fig. 1 of Zhou teaches a passivation layer (“passivation layer 10 may be made of a transparent and insulating material”, col 12, lines 1-2, from Noudo: “An arrow in FIG. 3 represents this state, in which a solid line represents light transmitted through the photoelectric conversion section 101 of the pixel 100 and incident on the polarization section 130”, col. 11, lines 10-13, as seen in Fig. 3, the arrow passes through 151 indicating that 151 is transparent to, as 151 is transparent and insulating, 151 is therefore a passivation layer).
Therefore, it would have been obvious to one having ordinary skill in the art at the time the invention was effectively filed to implement “a passivation layer” as taught by Zhou in the system of Noudo for the purpose of passivating the layers beneath and preventing undesired oxidation after device manufacturing.
Noudo in combination with Zhou fails to disclose “a conductive pattern disposed on the passivation layer; and

a first flat area disposed on the passivation layer and extending in the first direction; and

However, in a similar field of endeavor, Fig. 2B of Kusunoki teaches a conductive pattern (“conductive layer 104”, [0107], “the insulating layer 103 functions as an etching stopper when the conductive layer 104 is processed (etched)”, [0205], 104 is a discrete layer that has been etched and is therefore a conductive pattern) disposed on the passivation layer (as seen in Fig. 2B, 104 is disposed on 103 which is equivalent to 151 of Noudo); and
an adhesive layer (“an insulating layer 105”, [0107], “As the insulating layer 105, an inorganic insulating film or an organic insulating film can be used. For example, resins such as an acrylic resin and an epoxy resin, and inorganic insulating materials such as silicon oxide, silicon oxynitride, silicon nitride oxide, silicon nitride, and aluminum oxide can be given”, [0202], “For the adhesive layer 107, a variety of curable adhesives such as a photocurable adhesive like an ultraviolet curable adhesive, a reactive curable adhesive, a thermosetting adhesive, and an anaerobic adhesive can be used. Examples of these adhesives include an epoxy resin, an acrylic resin…”, [0206], both 105 and the adhesive layer 107 can be made from the same material, thus 105 is also an adhesive layer, further, as Kusunoki does not explicitly state that 105 is both an insulating layer and an adhesive layer, a secondary reference will be utilized to teach this limitation below) deposited on the passivation layer and the conductive pattern (as seen in Fig. 2B, 105 is disposed directly on 103 and 104), wherein the conductive pattern includes:
a first flat area (as seen in the enlarged Fig. 2B, the area denoted “FA1” is a first flat area), disposed on the passivation layer (as seen in the enlarged Fig. 2B, FA1 is disposed on 103) and extending in the first direction (as seen in the enlarged Fig. 2B, FA1 extends in the horizontal direction); and
an inclined area (as seen in the enlarged Fig. 2B, the area denoted “IA1” is an inclined area) connected to the first flat area (as seen in the enlarged Fig. 2B, IA1 is connected to FA1),
wherein a first top face of the inclined area (as seen in the enlarged Fig. 2B, the face denoted “TF1” is a first top face of the inclined area) is bent from a second top face of the first flat area (as seen in the enlarged Fig. 2B, the face denoted “TF2” is a second top face of the first flat area, further, TF1 is bent from TF2),
wherein the first top face has a constant slope with respect to the second top face (as seen in the enlarged Fig. 2B, TF1 has a constant slope with respect to TF2),
wherein the inclined area has an inclined shape with a slope of a first angle relative to a boundary where the first flat area and the inclined area meet each other (as seen in the enlarged Fig. 2B, IA1 has an inclined shape with a slope of a first angle relative to the vertical boundary between IA1 and FA1), and
wherein the adhesive layer includes a bent portion (as seen in the enlarged Fig. 2B, “P2” is bent portion of 105) having an inclination of a second angle relative to the boundary (as seen in the enlarged Fig. 2B, P2 has an inclination of a second angle relative to the vertical boundary between IA1 and FA1), wherein the first angle and the second angle are equal to each other (as seen in the enlarged Fig. 2B, the second angle of P2 is equal to the first angle of IA1, furthermore, as 105 is disposed directly on 104, the second angle P1 will necessarily be equal to the first angle of IA1).
Therefore, it would have been obvious to one having ordinary skill in the art at the time the invention was effectively filed to implement “a conductive pattern disposed on the passivation layer; and
an adhesive layer deposited on the passivation layer and the conductive pattern, wherein the conductive pattern includes:
a first flat area disposed on the passivation layer and extending in the first direction; and
an inclined area connected to the first flat area,
wherein a first top face of the inclined area is bent from a second top face of the first flat area,
wherein the first top face has a constant slope with respect to the second top face, and wherein the inclined area has an inclined shape with a slope of a first angle relative to a boundary where the first flat area and the inclined area meet each other,
wherein the inclined area has an inclined shape with a slope of a first angle relative to a boundary where the first flat area and the inclined area meet each other, and
wherein the adhesive layer includes a bent portion having an inclination of a second angle relative to the boundary, wherein the first angle and the second angle are equal to each other” as taught by Kusunoki in the system of Noudo in combination with Zhou for the purpose of forming a touch sensor (“a touch sensor is formed by the conductive layer 104 and the conductive layer 106 which are formed with the insulating layer 105 therebetween”, [0192]).
Noudo in combination with Zhou and Kusunoki fails to directly disclose “an adhesive layer deposited on the passivation layer and the conductive pattern”.
However, in a similar field of endeavor, Figs. 1A-1G of Liu teach an adhesive layer (“In one embodiment, the adhesive layer 360 may comprise epoxy resin, inorganic materials (such as silicon oxide, silicon nitride, silicon oxynitride, metal oxide or a combination thereof), organic polymer materials (such as polyimide, butylcyclobutene (BCB), parylene, polynaphthalenes, fluorocarbons or acrylates) or other suitable insulating materials”, col. 7, lines 38-44, thus 360 which can be an epoxy resin, is both an adhesive layer and an insulating material, where 360 of Liu is equivalent to 105 of Kusunoki) deposited on the passivation layer and the conductive pattern (as previously discussed 105 of Kusunoki is disposed directly on 103 and 104 of Kusunoki).
Therefore, it would have been obvious to one having ordinary skill in the art at the time the invention was effectively filed to implement “an adhesive layer deposited on the passivation layer and the conductive pattern” as taught by Liu in the system of Noudo in combination with Zhou and Kusunoki for the purpose of improving structural reliability by using an insulating layer that also serves to bond adjacent layers together.
Regarding claim 2, Fig. 3 of Noudo in combination with Fig. 1 of Zhou, Fig. 2B of Kusunoki, and Figs. 1A-1G of Liu disclose the image sensor of claim 1, Fig. 2B of Kusunoki further discloses wherein the first top face has a slope of the first angle with respect to a second direction perpendicular to the first direction (the vertical direction is a second direction perpendicular to the horizontal direction, TF1 has a slope of the first angle with respect to the vertical direction), and
wherein the first angle is greater than 0 degrees and smaller than 90 degrees (as seen in Fig. 2B, the first angle of the slope of TF1 is greater than 0 degrees and less than 90 degrees).

Regarding claim 9, Fig. 3 of Noudo discloses an image sensor (“pixel array section 10”, col. 6, line 39) comprising:
a substrate (“semiconductor substrate 141”, col. 8, line 12) having a photoelectric conversion element (“photoelectric conversion section 101”, col. 8, line 16) disposed therein (as seen in Fig. 3, 141 has 101 disposed therein);
a layer (“insulating film 151”, col. 8, line 11) disposed on the substrate (as seen in Fig. 3, 151 is disposed on 141) and extending in a first direction (as seen in Fig. 3, 151 extends in a horizontal direction).
Noudo fails to disclose “a passivation layer;
a conductive pattern formed on the passivation layer; and
an adhesive layer formed along the conductive pattern and formed on the passivation layer,
wherein the conductive pattern includes:
a first flat area extending from the passivation layer in a second direction perpendicular to the first direction and extending so as to have a first constant thickness; and
an inclined area, wherein a thickness of the conductive pattern in the inclined area from the passivation layer in the second direction decreases from the first thickness as the conductive pattern in the inclined area extends away from the first flat area in the first direction,
wherein the inclined area has an inclined shape with a slope of a first angle relative to a boundary where the first flat area and the inclined area meet each other, and
wherein the adhesive layer includes a bent portion having an inclination of a second angle relative to the boundary, wherein the first angle and the second angle are equal to each other.”
However, in a similar field of endeavor, Fig. 1 of Zhou teaches a passivation layer (“passivation layer 10 may be made of a transparent and insulating material”, col 12, lines 1-2, from Noudo: “An arrow in FIG. 3 represents this state, in which a solid line represents light transmitted through the photoelectric conversion section 101 of the pixel 100 and incident on the polarization section 130”, col. 11, lines 10-13, as seen in Fig. 3, the arrow passes through 151 indicating that 151 is transparent to, as 151 is transparent and insulating, 151 is therefore a passivation layer).

a pad (“conductive plug 156”, col. 7, line 7) disposed in the trench (as seen in Fig. 13, 156 is in 148) and on the conductive pattern (as seen in Fig. 13, 156 is disposed on 152).
Regarding claim 18, Fig. 3 of Noudo in combination with Fig. 1 of Zhou, Figs. 12 and 13 of Hsu, Fig. 2B of Kusunoki, and Figs. 1A-1G of Liu disclose the image sensor of claim 17, Figs. 12 and 13 of Hsu further disclose wherein the adhesive layer non-overlaps the pad (as seen in Fig. 13, the top of 152 is fully exposed, furthermore, it would be obvious to one skilled in the art to non-overlap 152 of Hsu with 105 of Kusunoki to maintain electrical conductivity with 152).
Regarding claim 19, Fig. 3 of Noudo in combination with Fig. 1 of Zhou, Figs. 12 and 13 of Hsu, Fig. 2B of Kusunoki, and Figs. 1A-1G of Liu disclose the image sensor of claim 17, Fig. 2B of Kusunoki further discloses wherein the top face of the bent portion has a slope of a second angle with respect to the top face of the passivation layer (as seen in Fig. 2BC17B, the top face of BP has a slope of a second angle with respect to TFP), and
wherein the second angle is greater than 0 degrees and smaller than 90 degrees (as seen in Fig. 2BC17B, the slope of the second angle is greater than 0 degrees and smaller than 90 degrees).
Regarding claim 20, Fig. 3 of Noudo in combination with Fig. 1 of Zhou, Figs. 12 and 13 of Hsu, Fig. 2B of Kusunoki, and Figs. 1A-1G of Liu disclose the image sensor of claim 19, Fig. 2B of Kusunoki further discloses wherein the bent portion and the first extension of the adhesive layer are provided on a side of the conductive layer including the inclined area (as seen in Fig. 2BC17B, BP and FE are provided on an end of 104 including IA1).
Allowable Subject Matter
Claim 16 is 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. The following is a statement of reasons for the indication of allowable subject matter: The prior art of record does not teach or fairly suggest the image sensor as recited in the claims of the instant application.
Regarding claim 16, together the prior art of Noudo (US 11,387,265 B2) in combination with Zhou et al. (US 11,296,249 B2), Kusunoki et al. (US 20240381702 A1), and Liu et al. (US 9,379,072 B2) disclose a similar image sensor but fail to disclose the specific limitations recited in the instant invention regarding the trench structure and the required arrangement of elements neighboring it e.g. “a trench extending through the insulating layer, the substrate, and the passivation layer, wherein each of the conductive pattern and the adhesive layer extends along a profile of the trench; and
a low refractive index layer filling an entirety of the trench so as to be surrounded with the adhesive layer; and
a photoresist disposed on a top face of the low refractive index layer.”
