Filed: 2000-10-27
Abstract: PURPOSE: A method for fabricating a semiconductor device is provided to prevent erosion of a cell region due to overpolishing and further to allow global planarization. CONSTITUTION: After a gate insulating layer is formed on a semiconductor substrate(21) having the cell region and a peripheral region, a polysilicon layer(22), a tungsten silicide layer(23) and a cap insulating layer(24) are sequentially formed thereon and then selectively patterned to have spaces. Particularly, the spaces in the peripheral region are smaller than those in the cell region. Next, an insulating sidewall(25) is formed on lateral sides of the patterned layers(22,23,24). Owing to smaller spaces, the insulating sidewall(25) in the peripheral region fills the spaces and thereby renders an increase in height to the peripheral region. Next, an ILD layer(26) is wholly formed and then polished for planarization. Since the peripheral region becomes higher by the insulating sidewall(25), the cell region is preserved from overpolishing and resulting erosion.
