Abstract:
A method of manufacturing a semiconductor device includes: forming an isolation region comprising a dielectric material on a substrate; forming a recess in the isolation region, wherein a thickness of the isolation region is reduced but greater than zero in the recess; forming a fill layer or layer stack including at least one of a semiconductor or metal on the isolation region and which conforms to the recess; forming a dishing prevention layer or layer stack on the fill layer or layer stack and which conforms to the recess; planarizing the dishing prevention layer or layer stack and the fill layer or layer stack to confine the dishing prevention layer or layer stack and the fill layer or layer stack to the recess, wherein the planarizing stops on the isolation region outside the recess; and forming one or more electrical contacts to the fill layer or layer stack confined to the recess.

Claim (Index 10):
The method of  claim 1 , wherein forming the one or more electrical contacts to the fill layer or layer stack confined to the recess comprises:\n forming a dielectric layer over the isolation region and contacting a top surface of the dishing prevention layer or layer stack confined to the recess; forming contact openings which extend through the dielectric layer in a periphery region of the recess; and forming an electrically conductive material on the dielectric layer and which fills the contact openings to make electrical contact with the fill layer or layer stack in the periphery region of the recess.
