Abstract:
A shallow trench isolation (STI) structure is formed having a conventional STI trench structure formed of dielectric material extending into the substrate. A planarizing stack of nitride and oxide is formed above the STI trench structure (and optionally a dummy gate may be formed above this stack). After further conventional processing, the nitride layer results in a structure that extends laterally outward beyond the outer edges of the underlying STI structure—creating a shadow or umbrella structure. The S/D cavity is formed (between the active gate and dummy gate) and the epitaxial S/D regions are grown. The placement and configuration of the nitride layer assists in reducing the amount of substrate material removed adjacent the STI structure during the S/D region cavity formation.

Claim (Index 16):
The method in accordance with  claim 15  wherein the protective layer extends laterally outward beyond both the first sidewall and the second sidewall of the dummy gate structure at least about 5 nanometers.
