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 4):
The method of  claim 3 , wherein planarizing the first portion of the dielectric layer by the CMP leaves the second portion of the dielectric layer over the hard mask of gate stacks in the isolated region.
