§103
DETAILED ACTION Notice of 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 . Response to Amendment The amendment with respect to claim(s) 1-2, 5-6 filed on 9/29/2026 have been fully considered for examination based on their merits. The previously presented claim(s) 3-4, and 7-12 have been considered. New Claim(s) 21-24 have been considered and entered. Response to Arguments Applicant’s arguments, see Remarks, pages 6-7, filed 07/06/2026, with respect to the rejection(s) of claim(s) 1-12 under 35 U.S.C. 102(a)(1) have been fully considered and are persuasive. Therefore, the rejection has been withdrawn. However, upon further consideration, a new ground(s) of rejection is made in view of PARK and OKUDA. Regarding Claim(s) 1 and 5. The Applicant argues (see Remarks, page 6) that KATO art fails to disclose or suggest the amended features to claims 1, and 5, now recites, “a dry film resist layer on the solder resist layer wherein the dry film resist layer defines a second section of the channel that the external via is formed within.” The Examiner agrees that the arguments are persuasive and therefore, the rejection has been withdrawn. However, upon further consideration, a new ground(s) of rejection is made as mentioned in the above paragraph. For instance, the prior-art of PARK teaches an electronic device having solder resist layer and dry film resist layer stacked and defines as first and second section of a channel. OKUDA teaches an electronic device, comprising a top layer placed on the portion of the conductor pad and made of gold material. A typo error found in the Remarks, page 6, filed on 07/06/2026, wherein the Applicant mentioned, Claim 6 as amended, now recites similar to amended claim 1. However, the amended claims received on 07/06/2026, the amendment was with respect to an independent claim 5. The dependent claim 6 amended similar to claim 2 as entered for examination. Regarding Claims 2-4, 6-12, and 21-24: The dependent claims 2-4, 6-12 and 21-24, follow similar arguments as Claims 1 and 5, upon further consideration, a new-grounds of rejection is made based on the prior-art mentioned above. Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.

Regarding Claim 22, KATO as modified by PARK, OKUDA and ADACHI teaches the electronic device of claim 1. KATO as modified by PARK, OKUDA and ADACHI does not explicitly disclose the electronic device, wherein the dry film resist layer has a hydrophilicity before curing. LEE teaches the electronic device (Fig. 3, 1a, polymerase chain reaction chip), wherein the dry film resist layer (Figs. 2/3, 20a, DFR material) has a hydrophilicity (Fig. 1, since DFR is hydrophilic, it can easily bond with a glass wafer with any special treatment, [page 5 last line; and page 6, first line]) before curing. Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention (AIA ) to have KATO as modified by PARK, OKUDA and ADACHI to incorporate the teachings of LEE, such that the electronic device, wherein the dry film resist layer has a hydrophilicity before curing, so that it can easily bond with a glass wafer without any special treatment (LEE, [page 5 last line; and page 6, first line]). KATO as modified by PARK, OKUDA, ADACHI and LEE does not explicitly disclose the electronic device, wherein the hydrophilicity allows the dry film resist layer to absorb a liquid and swell. VOGT teaches the electronic device (immersion lithography tool, HMDS treated silicon wafers, [Abstract, page 31; conclusion, page 37]), wherein the hydrophilicity allows the dry film resist layer (photoresist films, [Conclusion, page 37]) to absorb a liquid (D2O absorption, [Methods, page 33]) and swell (Fig. 3(a) and 3(b), a total film thickness increases due to the absorption of D2O was observed as the film swelled to 386 Å; a greater extent of swelling is observed, as expected due to the presence of the more hydrophilic hydroxyl groups). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention (AIA ) to have KATO as modified by PARK, OKUDA and ADACHI to incorporate the teachings of VOGT, such that the electronic device, wherein the hydrophilicity allows the dry film resist layer to absorb a liquid and swell, so that the excess water at the interface also manifests itself as a thickness dependent swelling for thin films, allowing for observation of interfacial concentration heterogeneities (VOGT, [Conclusion, page 38]). Regarding Claim 24, KATO as modified by PARK, OKUDA and ADACHI teaches the electronic device of claim 5. KATO as modified by PARK, OKUDA and ADACHI does not explicitly disclose the electronic device, wherein the dry film resist layer has a hydrophilicity before curing. LEE teaches the electronic device (Fig. 3, 1a, polymerase chain reaction chip), wherein the dry film resist layer (Figs. 2/3, 20a, DFR material) has a hydrophilicity (Fig. 1, since DFR is hydrophilic, it can easily bond with a glass wafer with any special treatment, [page 5 last line; and page 6, first line]) before curing. Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention (AIA ) to have KATO as modified by PARK, OKUDA and ADACHI to incorporate the teachings of LEE, such that the electronic device, wherein the dry film resist layer has a hydrophilicity before curing, so that it can easily bond with a glass wafer without any special treatment (LEE, [page 5 last line; and page 6, first line]). KATO as modified by PARK, OKUDA, ADACHI and LEE does not explicitly disclose the electronic device, wherein the hydrophilicity allows the dry film resist layer to absorb a liquid and swell. VOGT teaches the electronic device (immersion lithography tool, HMDS treated silicon wafers, [Abstract, page 31; conclusion, page 37]), wherein the hydrophilicity allows the dry film resist layer (photoresist films, [Conclusion, page 37]) to absorb a liquid (D2O absorption, [Methods, page 33]) and swell (Fig. 3(a) and 3(b), a total film thickness increases due to the absorption of D2O was observed as the film swelled to 386 Å; a greater extent of swelling is observed, as expected due to the presence of the more hydrophilic hydroxyl groups). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention (AIA ) to have KATO as modified by PARK, OKUDA and ADACHI to incorporate the teachings of VOGT, such that the electronic device, wherein the hydrophilicity allows the dry film resist layer to absorb a liquid and swell, so that the excess water at the interface also manifests itself as a thickness dependent swelling for thin films, allowing for observation of interfacial concentration heterogeneities (VOGT, [Conclusion, page 38]).
