`
`DETAILED ACTION
`
`Drawings
`
`.This application has been filed with informal drawings which
`
`are acceptable for examination purposes only.
`
`Formal drawings
`
`will be required when the application is allowed.
`
`Field of Search
`
`the Patent and
`This office action has been created under
`Trademark Office Semiconductor Technology Quality Assurance Pilot
`Program.
`It incorporates the examination quality standards set as
`a
`result of
`customer
`focus
`sessions with the
`semiconductor
`industry.
`The listing of the field of search to follow is one of
`these standards.

`
`Claim Rejections - 35 USC § 102
`
`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)
`the invention was known or used by others in this
`country, or patented or described in a printed publication
`in this or a foreign country, before the invention thereof
`by the applicant for a patent.
`
`
`
`Serial Number: O8/561,951
`Art Unit: 2503
`
`-3-
`
`the invention was patented or described in a printed
`(b)
`publication in this or a foreign country or in public use or
`on sale in this country, more than one year prior to the
`date of application for patent in the United States.
`
`Claims l—l2 are rejected under 35 U.S.C.
`
`§ 102(a) as being
`
`anticipated by Kinoshita.
`
`Kinoshita discloses a semiconductor device comprising:
`
`a
`
`silicon substrate (40), a diffusion region (46)
`
`formed within
`
`said substrate,
`
`a polysilicon gate electrode (26)
`
`formed on a top
`
`surface of said substrate wherein said gate is adjacent to but
`
`not
`
`in contact with said diffusion region, an insulating layer
`
`(38)
`
`such as silicon oxide or silicon nitride formed over said
`
`gate and said diffusion region wherein a contact hole (32)
`
`is
`
`formed in said insulating layer over said diffusion region, and a
`
`conducting plug formed of tungsten fills said contact hole. Note
`
`Kinoshita figure 5. Therefore, Kinoshita meets and anticipates
`
`the claims.
`
`Claims 1-12 are rejected under 35 U.S.C. § l02(b) as being
`
`anticipated by Nishigoori.
`
`Nishigoori discloses a semiconductor device comprising:
`
`a
`
`silicon substrate (1),
`
`a diffusion region (7)
`
`formed within said
`
`substrate and adjacent a top surface of said substrate,
`
`a
`
`polysilicon gate electrode (4)
`
`formed on said top surface of said
`
`substrate wherein said gate is adjacent to and not
`
`in contact
`
`with said diffusion region, an insulating layer (8) deposited
`
`over said substrate and covering at least a portion of said gate
`
`
`
`Serial Number: O8/561,951
`Art Unit: 2503
`
`-4-
`
`and said diffusion region wherein said insulating layer has a
`
`contact hole (12) over said diffusion region, and a contact plug
`
`(9)
`
`formed of tungsten filling said Contact hole. Note
`
`Nishigoori figure 3c. Therefore, Nishigoori meets and
`
`anticipates the claims.
`
`Conclusion
`
`The prior art made of record and not relied upon is
`
`considered pertinent to applicant's disclosure.
`
`The references to Watanabe, Sato and Nishiyama are cited to
`
`show semiconductor device structures similar to that of the
`
`present invention.
