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 .
Continued Examination Under 37 CFR. 1.114
A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued under 37 CFR 1.114, and fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant’s submission filed on 2/9/2026 has been entered.
Response to Arguments
Applicant's arguments filed 2/9/2026 have been fully considered but they are not persuasive.
#1 - Applicant argues that Watanabe fails to teach or imply “configured to generate plasma in a substantially linear subregion extending from the first edge to the second edge.”
Examiner respectfully disagrees.
Watanabe teaches generating plasma (Col. 4, lines 60-62) in a substantially linear subregion (annotated below) extending from the first edge (the left c, annotated below) to the second edge (the right b, annotated below).

#2 - Applicant alleges that Watanabe includes a lattice arrangement of discrete electrodes (shown in figs. 4-9) which is significant different from both “linear plasma sources” and “substantially parallel electrodes”,
However, Watanabe’s figures 4-9 are merely the examples of electrode formation. Watanabe’s other embodiments, such as figures 2 and 11 clearly teaches linear formation formed by so called discrete electrodes (see annotated figure 2 above).
# 3 - Applicant alleges that Watanabe will not generate plasma in a substantially linear subregion extending from the first edge to the second edge because Watanabe generates electric force pointing in opposite direction (figure 13).
However, the direction of electric force is seemingly irrelevant to the claimed limitation. Besides, Figure 13 is one of the embodiments in Watanabe. Other Watanabe’s embodiments in Figures 2 and 11 teach the claimed invention. Further, as discussed in argument #1, Watanabe teaches generating plasma (Col. 4, lines 60-62) in a substantially linear subregion (See annotated figure 2 above) extending from the first edge (the left c, see annotated figure 2 above) to the second edge (the right b, see annotated fig. 2 above).
#4 - Applicant argues that Hussey teaches away from the claimed arrangement including “a dielectric support to which electrodes of the array of plasma sources are secured”.
Examiner respectfully disagrees.
The only limitation not literally disclosed in Watanabe is linear plasma sources. Hussey clearly teaches linear plasma source in figs. 14, 28. The electrodes are not only linear but also elongated. Dielectric support is trivial in Hussey since primary reference Watanabe teaches dielectric support (susceptor 13, see figs. 1 and 19 of Watanabe).
Claim Rejections – 35 U.S.C. 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 1-9 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.
Regarding Claim 1, “each linear plasma source is configured to generate plasma in a substantially linear subregion extending from the first edge to the second edge” is not consistent with the specification and abstract of the application.
According to abstract, paragraphs [005], [006], [007], [037], [038], the disclosure literally teaches “The first electrode extends from a first edge of a plasma generating region to a second edge of the plasma generating region.” It seemingly teaches that the plasma generating region extending from a first edge to a second edge. However, it appears that it does not teach the plasma source generating plasma from the first edge to the second edge. Clarification is respectfully encouraged.
Claims 2-9 are not clear due to their dependency on Claim 1.
Claim Rejections – 35 U.S.C. 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.
Claim(s) 1-5, 8, 9, as best understood, is/are rejected under 35 U.S.C. 103 as being unpatentable over Watanabe (5,609,690) in view of Hussey et al. (2022/0134303).
Regarding Claim 1, Watanabe (5,609,690) discloses a plasma generating component for a process chamber, comprising:
an array of plasma sources (formed as an array, figs. 2, 11) wherein:
each of plasma source (electrodes) of the array (figs. 2 and 11) of the plasma sources forming substantially linear plasma sources (all the electrodes in row a form as a plasma source. So do row b and row c), extending along an approximate straight line (all a, b, c electrodes are extending along a straight line, see figs. 2, 11);
the linear plasma sources of the array of the plasma sources are substantially parallel to each other (15a, b, c are parallel each other, figs. 2, 11);
each plasma source of the array of plasma sources, comprises a pair of substantially parallel electrodes (15a, b, c are parallel, see figs. 2, 11), and wherein each electrode extends along the approximately straight line from a first edge (15c on the left edge, fig. 1) of a plasma generating region of the plasma generating component to a second edge (15b on the right edge, fig. 1), opposite the first edge, of the plasma generating region (fig. 1), and each linear plasma source is configured to generate plasma (Col. 4, lines 60-62) in a substantially linear subregions (See annotated figure 2 below. Each labeled elongated rectangle illustrates a linear subregion) extending from the first edge (the left c, annotated below) to the second edge (the right b, annotated below).
a dielectric support (susceptor 13) to which electrodes of the array of substantially parallel linear plasma sources are secured (figs. 1, 19); and
a dielectric material (insulating component 33, fig. 20) disposed opposite the dielectric support (13, fig. 19) with respect to the array of substantially parallel linear plasma sources (32) (fig. 20) (Col. 5, lines 14-25).

As discussed above, Watanabe essentially discloses the claimed invention but does not literally disclose linear plasma sources.
However, Hussey et al. (2022/0134303) teaches linear electrodes (e.g. cylinder) to produce plasma (Fig. 28, paragraphs [0370], [0400]).
It would have obvious to one of ordinary skill in the art at the time the invention was filed to have provided linear electrode in Watanabe in order to produce more uniform plasma radiation from the elongate electrodes as taught by Hussey.
Regarding Claim 2, Watanabe in view of Hussey discloses the plasma generating component of claim 1, wherein a first electrode (15a on the left column) of each pair of linear substantially parallel electrodes is electrically coupled to a first terminal of a power supply (16a) (fig. 1), and a second electrode (15a in the middle column) of each pair of linear substantially parallel electrodes is electrically coupled to a second terminal of the power supply (16a) (fig. 1).
Regarding Claim 3, Watanabe in view of Hussey discloses the plasma generating component of claim 2, wherein the first electrode (15a on the left column near the left edge, fig. 2) of each pair of linear substantially parallel electrodes is electrically coupled to the first terminal proximate the first edge (left edge) of the plasma generating region, and wherein the second electrode of each pair of linear substantially parallel electrodes is electrically coupled to the second terminal of the power supply proximate the second edge (15a on right column near the right edge) of the plasma generating region.
Regarding Claim 4, Watanabe in view of Hussey discloses the plasma generating component of claim 2, wherein a first electrode (15a on the left column near the left edge, fig. 2) of a first pair of linear substantially parallel electrodes is adjacent a second electrode (15a on right column near the right edge) of a second pair of linear substantially parallel electrodes, and wherein the first electrode (15a on the left column near the left edge, fig. 2) of the first pair of linear substantially parallel electrodes is electrically coupled to the first terminal of the power supply (16a), and the second electrode (15a on right column near the right edge) of the second pair of linear substantially parallel electrodes is electrically coupled to the first terminal of the power supply (fig. 2).
Regarding Claim 5, Watanabe in view of Hussey discloses the plasma generating component of claim 1, wherein a first plurality of substantially parallel linear plasma sources (15a) are electrically coupled together (fig. 2), and electrically decoupled from a linear plasma source (15b, fig. 2) of the plasma generating component that is not of the first plurality of substantially parallel linear plasma sources (15b is not part of 15a, and they are decoupled from each other, fig. 2).
Regarding Claim 8, Watanabe in view of Hussey discloses the plasma generating component of claim 1, further comprising: a first gas inlet (17) disposed on a first side of the plasma generating component (fig. 1); and a gas outlet (18), fluidly coupled to the gas inlet, disposed on a second side of the plasma generating component, opposite the first side (fig. 1).
As discussed above, Watanabe essentially discloses the claimed invention but does not explicitly disclose a plurality of gas outlets, however, it would have been obvious to one of ordinary skill in the art to have provided multiple gas outlets in Watanabe in order to release more gas as desired which does not involve novel and unexpected result.
Regarding Claim 9, as discussed above, Watanabe essentially discloses the claimed invention but does not explicitly disclose the plasma generating component of claim 8, further comprising a second gas inlet fluidly coupled to a second plurality of gas outlets, wherein the first plurality of gas outlets are disposed in a first gas delivery zone, and the second plurality of gas outlets are disposed in a second gas delivery zone.
However, it would have been obvious to one of ordinary skill in the art to have provided multiple gas inlets in another gas delivery zone in Watanabe in order to inject more gas to the chamber as desired which does not involve novel and unexpected result.
Claim(s) 6, 7 as best understood, is/are rejected under 35 U.S.C. 103 as being unpatentable over Watanabe (5,609,690) in view of Hussey et al. (2022/0134303) further in view of Sato et al. (2018/0012768).
Regarding Claim 6, as discussed above, Watanabe in view of Hussey discloses the claimed invention but does not essentially disclose the plasma generating component of claim 1, wherein a power supply is electrically coupled to a first linear plasma source of the array of substantially parallel linear plasma sources and a second linear plasma source of the array of substantially parallel linear plasma sources; and wherein the power supply is configured to provide power to the first linear plasma source for a first duration, and to provide power to the second linear plasma source for a second duration, different from the first duration.
However, Sato et al. (2018/0012768) discloses a first linear plasma source of the array of substantially parallel linear plasma sources (E1) and a second linear plasma source of the array of substantially parallel linear plasma sources (E2); and wherein the power supply (21c) is configured to provide power to the first linear plasma source for a first duration (period of time, paragraphs [0099], [0100], [0107]), and to provide power to the second linear plasma source for a second duration, different from the first duration (duration controlled by the switches 25, fig. 9 of Sato).
It would have been obvious to one of ordinary skill in the art to have provided power within periods of time to the electrodes in Watanabe in order to generate desired plasma density as taught by Sato.
Regarding Claim 7, Watanabe in view of Hussey further in view of Sato discloses the plasma generating component of claim 6, wherein a first plurality of linear plasma sources comprises the first plasma source, and is disposed proximate an edge of the plasma generating region, and wherein a second plurality of linear plasma sources comprises the second plasma source, and is disposed to intersect a central area of the plasma generating region (fig. 2).
