Claim Rejections - 35 USC § 102/103
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.
Claims 3, and 20 are rejected under 35 U.S.C. 102(a)(1) as anticipated by or, in the alternative, under 35 U.S.C. 103 as obvious over Bach, Joseph et al. (US 20040082251 A1) in view of, if necessary, Nguyen; Andrew et al. (US 20140272211 A1). Bach is discussed above. Bach’s Figure 11 appears to show Bach’s inclination angle (Figure 11, <90º in 5, 90º in 3) within the claimed range. However, Bach does not quantify Back’s angle as being an inclination angle (Figure 11, <90º in 5, 90º in 3) of Back’s plurality of spray holes (3a-c, 5a-c; Figure 4,11) with respect to Back’s lower surface of Back’s body (5; Figure 8; [0047]-Applicant’s 210; Figure 7) is from 30° to 60° as claimed by claim 3 and 20.
If the Examiner’s grounds of anticipation are not accepted, then, Nguyen also teaches relatively positioned plates (210,220; Figure 2A-2D) with through holes and “acute” angle (theta; Figure 2A-[0048], [0051]) gas injeciton holes (212, 222; Figure 1,2).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention for Bach to optimize Bach’s inclination angle (Figure 11, <90º in 5, 90º in 3) as taught by Nguyen.
Motivation for Bach to optimize Bach’s inclination angle (Figure 11, <90º in 5, 90º in 3) as taught by Nguyen is for “reducing lines of site” as taught by Nguyen ([0051]).
Claim Rejections - 35 USC § 103
Claims 2 and 19 are rejected under 35 U.S.C. 103 as being unpatentable over Bach, Joseph et al. (US 20040082251 A1) in view of Kulshreshtha; Prashant Kumar et al. (US 20160099147 A1). Bach is discussed above. Bach does not teach:
The showerhead (3+5; Figure 3A,3B,4,8,11-Applicant’s 200; Figure 7) of claim 1, wherein a separation of the plurality of spray holes (3a-c, 5a-c; Figure 4,11) increases from a center of the lower surface of the body (5; Figure 8; [0047]-Applicant’s 210; Figure 7) to an edge of the lower surface of the body (5; Figure 8; [0047]-Applicant’s 210; Figure 7), as claimed by claim 2
The substrate (21; Figure 8; [0047]) treatment apparatus of claim 16, wherein a separation of the plurality of spray holes (3a-c, 5a-c; Figure 4,11) of the showerhead (3+5; Figure 3A,3B,4,8,11-Applicant’s 200; Figure 7) increases from a center of the lower surface of the body (5; Figure 8; [0047]-Applicant’s 210; Figure 7) to an edge of the lower surface of the body (5; Figure 8; [0047]-Applicant’s 210; Figure 7), as claimed by claim 19
Kulshreshtha also teaches a wafer processing system (Figure 3) including a separation (522; 524; Figure 5A) of the plurality of spray holes (520; Figure 5A) of the showerhead (346; Figure 5A-Applicant’s 200; Figure 7) increases from a center of the lower surface of the body (346; Figure 5A-Applicant’s 210; Figure 7) to an edge of the lower surface of the body (346; Figure 5A-Applicant’s 210; Figure 7).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention for Bach to optimize Bach’s spray hole distribution as taught by Kulshreshtha.
Motivation for Bach to optimize Bach’s spray hole distribution as taught by Kulshreshtha is for “gas flow modulation” to impart control over “local stress and overlay error of one or more patterned films” as taught by Kulshreshtha ([0049]).
Claim 23 is rejected under 35 U.S.C. 102(a)(1) as anticipated by or, in the alternative, under 35 U.S.C. 103 as obvious over Bach, Joseph et al. (US 20040082251 A1) in view of Nguyen; Andrew et al. (US 20140272211 A1). Bach does not teach Bach’s showerhead (3+5; Figure 3A,3B,4,8,11-Applicant’s 200; Figure 7) according to claim 21, wherein Bach’s inclination angle (Figure 11, <90º in 5, 90º in 3) of a number of Bach’s spray holes (3a-c, 5a-c; Figure 4,11) at an edge of Bach’s lower surface of Bach’s body (5; Figure 8; [0047]-Applicant’s 210; Figure 7) is larger than an inclination angle (Figure 11, <90º in 5, 90º in 3) of a number of Bach’s spray holes (3a-c, 5a-c; Figure 4,11) in a center of Bach’s lower surface of Bach’s body (5; Figure 8; [0047]-Applicant’s 210; Figure 7).
Nguyen is discussed above.
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention for Bach to optimize Bach’s inclination angle (Figure 11, <90º in 5, 90º in 3) as taught by Nguyen.
Motivation for Bach to optimize Bach’s inclination angle (Figure 11, <90º in 5, 90º in 3) as taught by Nguyen is for “reducing lines of site” as taught by Nguyen ([0051]).
Claim 23 is rejected under 35 U.S.C. 102(a)(1) as anticipated by or, in the alternative, under 35 U.S.C. 103 as obvious over Bach, Joseph et al. (US 20040082251 A1) in view of Lee; Sang-Gon (US 7381274 B2). Bach is discussed above. Bach further teaches:
The showerhead (3+5; Figure 3A,3B,4,8,11-Applicant’s 200; Figure 7) of claim 8, wherein the valve (3; Figure 8; [0047]-Applicant’s 220; Figure 7) further comprises: a first motor (70; Figure 8-”servo or stepper”; [0047]) configured to rotate (70, 140; Figure 8; [0047]) the plate (3; Figure 8; [0047]-Applicant’s 221; Figure 7) between the opened state and the closed state, and a seal (18; Figure 8) providing a seal between Bach’s shaft (2; Figure 8; [0047]) and Bach’s process chamber (6; Figure 8; [0047]) – claim 11
Bach does not teach Bach’s seal (18; Figure 8) is a magnetic fluid seal – claim 11.
Lee also teaches a wafer processing apparatus (Figure 2) gas injection column (1; Figure 2, 5) that rotates relative to a stationary gas plenum (2; Figure 2). Lee’s injected gas is sealed from the rotating shaft by magnetic fluid o-ring pairs (10-12; Figure 2; column 4; line 61-column 5; line 5).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention for Bach to use Lee’s magnetic fluid o-ring pairs as taught by Lee.
Motivation for Bach to use Lee’s magnetic fluid o-ring pairs as taught by Lee is for “excellent sealing property” as taught by Lee (column 4; line 61-column 5; line 5).
Claim 14 is rejected under 35 U.S.C. 102(a)(1) as anticipated by or, in the alternative, under 35 U.S.C. 103 as obvious over Bach, Joseph et al. (US 20040082251 A1) in view of Kim; Do-Hyeong (US 20060102286 A1). Bach is discussed above. Bach further teaches the showerhead (3+5; Figure 3A,3B,4,8,11-Applicant’s 200; Figure 7) of claim 13, further comprising a pipe (1; Figure 8) protruding from the body (5; Figure 8; [0047]-Applicant’s 210; Figure 7) and connected to a fluid supply (160; Figure 8) and configured to supply the fluid into the inlet space (2a; Figure 8; [0047]-Applicant’s 210a; Figure 7), wherein the pipe (1; Figure 8) comprises: a fixed pipe (1; Figure 8) fixed to the process chamber (6; Figure 8; [0047]); and a rotating pipe (2; Figure 8) rotatably coupled to the fixed pipe (1; Figure 8) about an axial direction – claim 14
However, Bach does not teach wherein Bach’s second shaft (between 71 and 70; Figure 8; [0047]) comprises: a second motor; and a transmission connected to the second motor and configured to transmit a rotational force to Bach’s rotating pipe (2; Figure 8) – claim 14
Kim also teaches a wafer processing apparatus (Figure 1) including gas injection plates (131, 134; Figure 1,2) that have relative rotational movement restricting flow between perforations (132, 135; Figure 2) using two motors (142, 143; Figure 2; [0034]).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention for Bach to add an plural motors and transmission as taught by Kim.
Motivation for Bach to add an plural motors and transmission as taught by Kim is for independent movement as taught by Kim ([0034]).
Claim 15 is rejected under 35 U.S.C. 102(a)(1) as anticipated by or, in the alternative, under 35 U.S.C. 103 as obvious over Bach, Joseph et al. (US 20040082251 A1) and Kim; Do-Hyeong (US 20060102286 A1) in view of Lee; Sang-Gon (US 7381274 B2). Bach is discussed above. Bach does not teach Bach’s showerhead (3+5; Figure 3A,3B,4,8,11-Applicant’s 200; Figure 7) of claim 14, wherein the second motor is provided on an upper portion of Bach’s process chamber (6; Figure 8; [0047]), wherein Bach’s second shaft (between 71 and 70; Figure 8; [0047]) is provided through a surface of Bach’s process chamber (6; Figure 8; [0047]), and wherein a magnetic fluid seal is provided between Bach’s second shaft (between 71 and 70; Figure 8; [0047]) and Bach’s process chamber (6; Figure 8; [0047]), as claimed by claim 15
Kim and Lee are discussed above.
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention for Bach to use Lee’s magnetic fluid o-ring pairs as taught by Lee and for Bach to add an plural motors and transmission as taught by Kim.
Motivation for Bach to use Lee’s magnetic fluid o-ring pairs as taught by Lee is for “excellent sealing property” as taught by Lee (column 4; line 61-column 5; line 5).
Motivation for Bach to add an plural motors and transmission as taught by Kim is for independent movement as taught by Kim ([0034]).
Claim 17 and 18 are rejected under 35 U.S.C. 102(a)(1) as anticipated by or, in the alternative, under 35 U.S.C. 103 as obvious over Bach, Joseph et al. (US 20040082251 A1) in view of Kato; Hitoshi et al. (US 20160138159 A1). Bach os discussed above. Bach does not teach:
Bach’s substrate (21; Figure 8; [0047]) treatment apparatus of claim 16, wherein Bach’s disk (7; Figure 8) is provided with a plurality of pockets onto which Bach’s substrate (21; Figure 8; [0047]) is seated, and the plurality of pockets are configured to rotate on a plane by a first rotating assembly, as claimed by claim 17
Bach’s substrate (21; Figure 8; [0047]) treatment apparatus of claim 17, wherein Bach’s disk (7; Figure 8) is provided on an bottom surface of Bach’s process chamber (6; Figure 8; [0047]) and configured to rotate by a second rotating assembly, as claimed by claim 18
Kato teaches a planetary rotation substrate disk (Figure 3, 5, 6) with the claimed mechanics.
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention for Bach to replace Bach’s disk with Kato’s disk.
Motivation for Bach to replace Bach’s disk with Kato’s disk is for “…, uniformity of the thickness of the SiO.sub.2 film in the circumferential direction of the wafer W can be improved.” as taught by kato ([0059]).
