  • Method for fabricating semiconductor device which prevents gates of a peripheral region from being oxidized
    Patent number: 6579757
    Abstract: A method of fabricating a semiconductor device, includes the steps of forming gates in a cell region and in a peripheral region of a substrate, forming a polysilicon layer over an entire surface of the resultant structure, partially removing portions of the polysilicon layer in the cell region to maintain the polysilicon layer of a predetermined thickness in the cell region, removing the predetermined thickness of the polysilicon layer both in the cell and peripheral regions, so that the resultant structure includes exposed gates in the cell region but no exposed gates in the peripheral region, and forming an insulating layer over the resultant structure.
    Type: Grant
