Abstract:
According to an exemplary embodiment, a method of forming an isolation layer is provided. The method includes the following operations: providing a substrate; providing a vertical structure having a first layer over the substrate; providing a first interlayer dielectric over the first layer; performing CMP on the first interlayer dielectric; and etching back the first interlayer dielectric and the first layer to form the isolation layer corresponding to a source of the vertical structure.

Claim (Index 10):
The method of  claim 7 , wherein the etching back the second ILD layer and the etch stop layer removes (i) the etch stop layer's horizontal upper portion and (ii) sections of the etch stop layer's vertical side portions that overlie the channel region, the drain region and the silicide layer, and does not remove sections of the etch stop layer's vertical portions that overlie the source.
