Abstract:
A method for forming a semiconductor device is provided. A plurality of trenches are formed in the substrate. An isolation oxide layer is formed in the trenches and on the substrate. A shield polysilicon is deposited in the trenches and on the isolation oxide layer on the substrate. A first etching process is performed to remove a first portion of the shield polysilicon. A first removal process is performed to remove a first portion of the isolation oxide layer. A second etching process is performed to remove a second portion of the shield polysilicon. A second removal process is performed to remove a second portion of the isolation oxide layer. An inter-poly oxide layer is formed on the remaining shield polysilicon and the remaining isolation oxide layer, wherein the inter-poly oxide layer has a concave top surface.

Claim (Index 28):
The method for forming the semiconductor device as claimed in  claim 21 , wherein the profile of the concave top surface of the inter-poly oxide layer is substantially the same as the profile formed by the top surface of the remaining isolation oxide layer and the top surface of the remaining shield polysilicon.
