Office Action

§103
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 . This is the initial Office action based on application number 18/105993 filed February 6, 2023. Claims 1-14 are currently pending and have been considered below. Election/Restrictions Claims 13-14 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected invention, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on November 17, 2025. Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claims 1, 2 and 8 are rejected under 35 U.S.C. 103 as being unpatentable over Sano et al. (US 2015/0262848) in view of Noda et al. (US 2011/0286738). Regarding claim 1: Sano et al. discloses a substrate processing apparatus chamber (10) having a spin chuck (20) which is a rotary holder that holds and spins a substrate (W), a processing cup (40) surrounding the substrate (W) and spin chuck (20), three processing liquid nozzles (30, 60, 65) provided on nozzle arms (32, 62, 67) which can all either provide coating liquids or removal liquids that remove films from the periphery of the substrate (par. 87), and a camera (70) that takes an image of the processing space above the spin chuck (20) (par. 92, figures 2-3). Sano et al. further discloses that a separate camera dedicated to one of the liquid nozzles (65) can also be provided in addition to the processing space camera (70) (par. 116), but fails to explicitly disclose that it is attached to the arm of the corresponding liquid nozzle (65). However, Noda et al. discloses a similar processing apparatus using a camera (17) which is meant to observe the dispensing process from a nozzle (10) which can either be mounted on the nozzle support arm (11) or provided separately (pars. 77-78, figures 2-3). It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to attach the camera of Sano et al. which is dedicated to one nozzle (30, 60, 65) to its arm (32, 62, 67) in the way described by Noda et al. because Noda et al. teaches that it being fixed to the arm or not are two functionally equivalent arrangements (par. 78) and simple substitution of functional equivalents is not considered to be a patentable advance (MPEP 2143, 2144.06). Regarding claim 2: Sano et al. discloses an exhaust duct (18) connected to a port in the wall (11) of the chamber (10) connected to an exhaust mechanism (par. 114, figure 3), as well as nozzle base (33, 63, 68) coupled to each nozzle arm (32, 62, 67) which is a movement shaft around which the arms (32, 62, 67) rotationally pivot (par. 99, figure 2), where the exhaust duct (18) can be considered to be in one of a front or rear area and at least one of the nozzle bases (33, 63, 68) can be considered to be on an opposite side (see figures 2-3). Regarding claim 8: Sano et al. discloses that the cameras are designed to take images of an imaging region (PA) above the substrate (W) to determine whether or not is in the proper processing position corresponding to a reference pattern (RP) over the center of the substrate (W) (pars. 128, 137, figures 8-9). In the combination having two cameras, one attached to the nozzle arm and one on a wall of the chamber, the second one inherently captures the image at a different angle. Claims 3, 10 and 11 are rejected under 35 U.S.C. 103 as being unpatentable over Sano et al. and Noda et al. as applied to claims 1-2 and 8 above, and further in view of Nakajima et al. (JP 2008135678, attached translation used for citation purposes). Regarding claim 3: Sano et al. and Noda et al. fail to explicitly disclose slide rails including a first and second rail that allow the cup (40) to be pulled out and replaced. However, Nakajima et al. discloses a similar processing apparatus in which the cup body (2) is provided on a moving mechanism (7) which includes a set of inner rails (71) which support the cup (2) and a slider (72) which is an outer rail that supports the inner rails (71) which allow the cup (2) to be pulled out in a predetermined direction (page 13, figure 7). It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to use such a cup movement mechanism as taught by Nakajima et al. for the cup (40) of Sano et al. because Nakajima et al. teaches that liquid processing cups need to be removed periodically and doing so without such a mechanism can be difficult and time consuming (pages 2-3). Regarding claim 10: Sano et al. and Noda et al. fail to explicitly disclose a drainpipe at a height lower than the exhaust duct. However, Nakajima et al. discloses a similar processing apparatus having both an exhaust port (25) for removing gasses and a drain pipe (52) for removing liquid waste connected to a drain port (26), the entry to the drain pipe (52) being at a height lower than that of the exhaust port (25), along with a liquid receiving mechanism (36) which prevents liquid from being accidentally discharged from the drain port (26) while moving (page 2, page 12, figures 1, 3-5 and 8). It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to include a drain and liquid receiving mechanism as taught by Nakajima et al. for the cup of Sano et al. because Nakajima et al. teaches that the drain allows for the easy removal of excess liquid and that the liquid receiving mechanism helps prevent liquid from spilling while removing the cup (page 2, 12). Regarding claim 11: Sano et al., Noda et al. and Nakajima et al. disclose the above combination including the liquid receiving mechanism (36) which has a lower portion which covers the bottom outlet of the drain port (26) such that it is a lid, as well as an upper extending flange portion which can be considered a handle that is continuous with the lid, and Nakajima et al. further teaches that the liquid receiving mechanism (36) is moved when replacing the cup (2) and is prevented from interfering when reinserting the drain port (26) back into the drain pipe (52), such that the liquid receiving mechanism needs to be slid to and from the retracted position during the replacement process (page 12, figure 8). While Nakajima et al. fails to explicitly disclose that this is done automatically via a stopper rotating the mechanism (36) via the handle, nonetheless it would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to automate this sliding process either by linear motion or rotary motion because automating an otherwise manual activity is not considered to be a patentable advance (MPEP 2144.04) and because choosing from a finite number of solutions (linear vs rotary motion) is not considered to be a patentable advance (MPEP 2143E). Claims 4-5 and 12 are rejected under 35 U.S.C. 103 as being unpatentable over Sano et al. and Noda et al. as applied to claims 1-2 and 8 above, and further in view of Kawabuchi et al. (US 2017/0236729). Regarding claim 4: Sano et al. and Noda et al. fail to explicitly disclose a standby bus provided in a standby section for any of the nozzles. However, Kawabuchi et al. discloses a similar liquid processing apparatus in which all of the nozzles (411-414) are provided with their own standby bus (251, 252) in order to suppress any moisture containing atmosphere from entering the nozzles when they are not being used (par. 151). It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to use a standby bus as taught by Kawabuchi et al. for the nozzles of Sano et al. because Kawabuchi et al. teaches that this prevents moisture from entering the nozzles (pars. 146-151). In the above combination, the camera provided on the nozzle arm (32, 62, 67) would also naturally acquire information on the position of that nozzle when it is in the standby bus. Regarding claim 5: Sano et al. and Noda et al. fail to explicitly disclose a standby bus provided in a standby section for any of the nozzles. However, Kawabuchi et al. discloses a similar liquid processing apparatus in which all of the nozzles (411-414) are provided with their own standby bus (251, 252) in order to suppress any moisture containing atmosphere from entering the nozzles when they are not being used (par. 151). It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to use a standby bus as taught by Kawabuchi et al. for the nozzles of Sano et al. because Kawabuchi et al. teaches that this prevents moisture from entering the nozzles (pars. 146-151). In the above combination, the any of the nozzle arms (32, 62, 67) can have attached cameras such that one of the nozzles (30, 60, 65) and its corresponding camera can be considered a removal liquid nozzle and a bus camera which faces the bus rather than the cup while the nozzle (30, 60, 65) is inserted into the standby bus (see Sano et al. figure 2). Regarding claim 12: Sano et al. discloses an illumination part (71) arranged inside the chamber (10) which provides light to all of the cameras (par. 117). While Sano et al., Noda et al. and Kawabuchi et al. do not explicitly discuss where the illuminator (71) would be relative to the nozzle (30, 60, 65) cameras which correspond to the claimed bus camera, it would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to try either putting it on the same side of the bus camera as the bus or the opposite side of the bus camera as the bus because trying from a finite number of solutions is not considered to be a patentable advance (MPEP 2143E). Claims 6-7 are rejected under 35 U.S.C. 103 as being unpatentable over Sano et al., Noda et al. and Kawabuchi et al. as applied to claims 1-2, 4-5, 8 and 12 above, and further in view of Hosokawa (JP 3414176, attached translation used for citation purposes). Regarding claims 6-7: Sano et al., Noda et al. and Kawabuchi et al. disclose the above combination having a number of standby buses for the various nozzles (30, 60, 65), but fail to explicitly discuss any of the material which the buses are formed of. However, Hosokawa discloses a similar processing apparatus having a standby pot (4) which is the same as a bus, where the pot (4) includes a solvent reservoir (9) and part of the surface of the pot (4) is formed of a quartz window (11), which is partially reflective (pages 2-3, figures 1-3). It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to use a pot with a solvent and a quartz window as taught by Hosokawa rather than the buses of Kawabuchi et al. because Hosokawa teaches that the solvent helps prevent crystallization of the material dispensed by the nozzles and the window allows easy and quick recognition of the solvent level in the pot (pages 2-3). While Hosokawa does not explicitly state that the rest of the surface is black, it would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to color the surface outside of the quartz window (11) black because aesthetic design choices are not considered to be a patentable advance (MPEP 2144.04). Claim 9 is rejected under 35 U.S.C. 103 as being unpatentable over Sano et al. and Noda et al. as applied to claims 1-2 and 8 above, and further in view of Kawabuchi et al. and Ye et al. (US 2021/0238374). Regarding claim 9: Sano et al. discloses three different nozzles, two of which can be considered a processing liquid nozzle and a coating liquid nozzle, the processing liquid being a solvent like water or DHF which can help a photoresist liquid, which can be considered the coating liquid, spread on the surface (par. 87). Sano et al. and Noda et al. fail to explicitly disclose putting two of those nozzles on the same nozzle arm, however Kawabuchi et al. discloses a similar processing apparatus having a single nozzle arm (43) holding a plurality of nozzles (411, 414) (par. 69, figure 3). It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to try using a single nozzle arm for multiple nozzles as taught by Kawabuchi et al. for at least two of the nozzles of Sano et al. because Kawabuchi et al. shows that this is a well-known functionally equivalent arrangement for similar liquid processing and simple substitution of functional equivalents is not considered to be a patentable advance (MPEP 2143, 2144.06). Sano et al. and Noda et al. teach that the cameras used have wide-angle lenses capable of viewing all the corresponding nozzles (Noda et al. par. 78) but none of Sano et al., Noda et al. or Kawabuchi et al. explicitly discloses a camera that uses a liquid lens. However, Ye et al. discloses a similar camera and imaging system which uses a liquid lens, teaching that they can offer substantial advantages for applications that need to focus and view different sized items at different locations (par. 74). It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to use a liquid lens camera like that of Ye et al. for the nozzle camera of Sano et al. because Ye et al. teaches that liquid lenses produced by their invention can offer substantial advantages for applications that need to focus and view different sized items at different locations (par. 74).
