Abstract:
A method of removing a hard mask is provided. Gate stacks are patterned on a substrate, where the gate stacks include a polysilicon layer and the hard mask deposited over the polysilicon layer. A dielectric layer is deposited on the substrate and on the patterned gate stacks. A first portion of the dielectric layer is planarized by chemical mechanical polishing (CMP) to remove a topography of the dielectric layer. The hard mask and a second portion of the dielectric layer are removed by the CMP.

Claim (Index 3):
The method of  claim 1 , wherein planarizing the first portion of the dielectric layer by the CMP causes the hard mask of gate stacks in the dense region to be exposed to the CMP.
