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 .
Claim Interpretation
The following is a quotation of 35 U.S.C. 112(f):
(f) Element in Claim for a Combination. – An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof.
The following is a quotation of pre-AIA 35 U.S.C. 112, sixth paragraph:
An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof.
The claims in this application are given their broadest reasonable interpretation using the plain meaning of the claim language in light of the specification as it would be understood by one of ordinary skill in the art. The broadest reasonable interpretation of a claim element (also commonly referred to as a claim limitation) is limited by the description in the specification when 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is invoked.
As explained in MPEP § 2181, subsection I, claim limitations that meet the following three-prong test will be interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph:
(A) the claim limitation uses the term “means” or “step” or a term used as a substitute for “means” that is a generic placeholder (also called a nonce term or a non-structural term having no specific structural meaning) for performing the claimed function;
(B) the term “means” or “step” or the generic placeholder is modified by functional language, typically, but not always linked by the transition word “for” (e.g., “means for”) or another linking word or phrase, such as “configured to” or “so that”; and
(C) the term “means” or “step” or the generic placeholder is not modified by sufficient structure, material, or acts for performing the claimed function.
Use of the word “means” (or “step”) in a claim with functional language creates a rebuttable presumption that the claim limitation is to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites sufficient structure, material, or acts to entirely perform the recited function.
Absence of the word “means” (or “step”) in a claim creates a rebuttable presumption that the claim limitation is not to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is not interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites function without reciting sufficient structure, material or acts to entirely perform the recited function.
Claim limitations in this application that use the word “means” (or “step”) are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. Conversely, claim limitations in this application that do not use the word “means” (or “step”) are not being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action.
This application includes one or more claim limitations that do not use the word “means,” but are nonetheless being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, because the claim limitation(s) uses a generic placeholder that is coupled with functional language without reciting sufficient structure to perform the recited function and the generic placeholder is not preceded by a structural modifier. Such claim limitation(s) is/are: “moving mechanism” in claim 1.
Because this/these claim limitation(s) is/are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, it/they is/are being interpreted to cover the corresponding structure described in the specification as performing the claimed function, and equivalents thereof.
If applicant does not intend to have this/these limitation(s) interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, applicant may: (1) amend the claim limitation(s) to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph (e.g., by reciting sufficient structure to perform the claimed function); or (2) present a sufficient showing that the claim limitation(s) recite(s) sufficient structure to perform the claimed function so as to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph.
Claim Rejections - 35 USC § 102
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 the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
Claim(s) 1-3, 5 and 6 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Okada (2004/0156028).
Regarding claim 1, Okada discloses an exposure apparatus (Fig. 2, 3), comprising: a light-emission unit (1) that emits exposure light (para 0058); a mask stage (MS) that holds an exposure mask (M1, M2, para 0058)); a workpiece stage (WS) that holds a workpiece (W, para 0059); a projection optical system (2) that irradiates the workpiece held by the workpiece stage with the exposure light, the exposure light being emitted from the light-emission unit and passing through the exposure mask (para 0060); a reflective member (4a, 4b) that is disposed in an irradiation region for the exposure light applied from the projection optical system in a step of detecting a mask mark (MAM, Fig. 3, para 0065), the mask mark being an alignment mark of the exposure mask (para 0065); an alignment microscope (3) that is disposed in an optical path of the exposure light applied to the mask mark and captures an image of the mask mark on a basis of reflected light that is reflected by the reflective member in the step of detecting the mask mark (para 0065); and a moving mechanism (inherent) that moves the reflective member from a position deviated from the irradiation region to the irradiation region in the step of detecting the mask mark (Fig. 2, 3, para 0065, 0066).
Regarding claim 2, Okada discloses wherein the workpiece stage includes a placement surface on which the workpiece is placed (Fig. 2), and the moving mechanism (inherent) moves the workpiece stage such that the placement surface is deviated from the irradiation region and moves the reflective member to the irradiation region in the step of detecting the mask mark (Fig. 3).
Regarding claim 3, Okada discloses wherein the moving mechanism inserts the reflective member between the workpiece stage and the alignment microscope to move the reflective member to the irradiation region in the step of detecting the mask mark (Fig. 3, para 0065).
Regarding claim 5, Okada discloses wherein the reflective member is connected to a position different from the placement surface of the workpiece stage, and the moving mechanism moves the workpiece stage to move the reflective member to the irradiation region (Fig. 2, 3).
Regarding claim 6, Okada discloses wherein the reflective member is connected to the workpiece stage such that a height position of a surface of the reflective member is equal to a height position of a surface of the workpiece placed on the placement surface.
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.
Claim(s) 4 and 9 is/are rejected under 35 U.S.C. 103 as being unpatentable over Okada in view of Tanaka (JP 8-233529 in IDS) (para numbers refer to the provided English translation).
Regarding claims 4 and 9, Okada does not disclose wherein the reflective member is formed to have a size equal to or larger than a size of the irradiation region, and reflects a whole of the exposure light applied from the projection optical system.
Tanaka discloses an exposure apparatus (Fig. 1, para 0007, 0009, 0036-0038), comprising: a light-emission unit (1) that emits exposure light; a mask stage (2) that holds an exposure mask (M, para 0042 (1)); a workpiece stage (4) that holds a workpiece (W, para 0042 (6)); a projection optical system (3) that irradiates the workpiece held by the workpiece stage with the exposure light, the exposure light being emitted from the light-emission unit and passing through the exposure mask (para 0042 (1); a reflective member (4a) that is disposed in an irradiation region for the exposure light applied from the projection optical system in a step of detecting a mask mark (MAM, para 0041), the mask mark being an alignment mark of the exposure mask (Fig. 1, para 0042 (1), (2)); an alignment microscope (5) that is disposed in an optical path of the exposure light applied to the mask mark and captures an image of the mask mark on a basis of reflected light that is reflected by the reflective member in the step of detecting the mask mark (para 0042 (3)(4)), wherein the reflective member (4a) is formed to have a size equal to or larger than a size of the irradiation region, and reflects a whole of the exposure light applied from the projection optical system (Fig. 1). Therefore, it would have been obvious to one of ordinary skill in the art to provide a reflective member formed to have a size equal to or larger than a size of the irradiation region, and reflects a whole of the exposure light applied from the projection optical system as taught by Tanaka to the invention of Okada in order to detect all of the mask marks on the mask at once using a plurality of alignment microscope since merely changing a side of a provide element requires only routine skill in the art.
Claim(s) 7 and 8 is/are rejected under 35 U.S.C. 103 as being unpatentable over Okada in view of Sugimoto (2008/0212047).
Regarding claim 7, Okada does not disclose a moving stage that holds the reflective member, wherein the moving mechanism moves each of the workpiece stage and the moving stage to move the reflective member to the irradiation region. Sugimoto disclose an exposure apparatus (Fig. 1) comprising a workpiece stage (2, para 0048) and a moving stage (3) for holding fiducial member for alignment (para 0050-0052). Although Sugimoto does not disclose a reflective member on the moving stage (3), it would have been obvious to one of ordinary skill in the art to provide a separate moving stage for the reflective member (4a) of Okada as taught by Sugimoto in order to provide flexibility in the movement of the workpiece stage and the moving stage with independent control of the stages.
Regarding claim 8, Okada discloses the reflective member is at a height position of a surface of the reflective member is equal to a height position of a surface of the workpiece placed on the placement surface (Fig. 2, 3). However, Okada does not disclose that the reflective member is held by the moving stage wherein the moving mechanism moves each of the workpiece stage and the moving stage along an identical plane. Sugimoto discloses the fiducial member for alignment on the moving stage (3, para 0050-0052) and the moving mechanism that moves each of the workpiece stage and the moving stage along an identical plane (Fig. 1, 2, para 0072-0074). Therefore, it would have been obvious to one of ordinary skill in the art to provide reflective member on the moving stage and to move each of the workpiece stage and the moving stage along an identical plane for the reasons stated above.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Sentoku et al. (7,148,973) is cited to show the state of art regarding detecting mask alignment mark (6).
