20170373144 · 2017-12-28 ·

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.
