    摘要: A test circuit includes a wafer, an insulative layer formed on the wafer, and a plurality of test structures formed in the insulative layer. Each of the test structures comprises a first comb having a first plurality of fingers and a second comb having a second plurality of fingers. The first and second pluralities of fingers are interleaved to define a finger spacing between the first and second pluralities of fingers. The finger spacing in a first one of the test structures being different than the finger spacing in a second one of the test structures. A method for characterizing damage in a semiconductor device includes providing a wafer having an insulative layer and a plurality of test structures formed in the insulative layer. The test structures have different geometries. An electrical characteristic of first and second test structures of the plurality of test structures is determined. The electrical characteristics of the first and second test structures is compared. Damage to the insulative layer is characterized based on the comparison.

    摘要: A method of forming minimal gaps or spaces in a polysilicon conductive lines pattern for increasing the density of integrated circuits by converting an area of the size of the desired gap or space in the polysilicon to silicon oxide, followed by removing the silicon oxide. The preferred method is to selectively ion implant oxygen into the polysilicon and annealing to convert the oxygen implanted polysilicon to silicon oxide. As an alternative method, an opening in an insulating layer overlying the conductive line is first formed by conventional optical lithography, followed by forming sidewalls in the opening to create a reduced opening and using the sidewalls as a mask to blanket implant oxygen through the reduced opening and into the exposed polysilicon conductive line. After annealing, the implanted polysilicon converted to silicon oxide and removed to form a gap or space in the polysilicon conductive line pattern substantially equal in size to the reduced opening. Instead of blanket implanting with oxygen, thermal oxidation can be used to convert the exposed polysilicon to silicon oxide.

    摘要: A method of forming field isolation in a semiconductor substrate, such as shallow oxide trenches, for isolation of FET transistors, including complementary FETs such as CMOS, with selected sections of said trenches extending above the substrate and being coplanar with the upper surface of subsequently formed polysilicon gates. An etch protective layer is used during the formation and the filling of the trench openings so that the top of the trenches are coplanar with upper surface of the etch protective layer. Selected sections of the trenches are masked and protected prior to planarization of the non-masked trenches to the bottom edge of the etch protective layer. After deposition and planarization of the poly, the upper surface of a deposited polysilicon layer for forming polysilicon gates of FET transistors is coplanar and self-aligned with the upwardly extending selected sections of the field isolation trenches.
