Abstract:
A shallow trench isolation (STI) structure is formed from a conventional STI trench structure of a first dielectric material extending into the substrate. The conventional STI structure undergoes further processing: removing a first portion of the dielectric material and adjacent portions of the semiconductor substrate to create a first recess, and then removing another portion of the dielectric material to create a second recess in just the dielectric material. A nitride spacer layer is formed above the remaining dielectric material and on the sidewalls of the substrate. A second dielectric material is formed on the spacer layer and fills the remainder of first and second recesses to a lever above the substrate. A nitride capping layer and another dielectric layer are disposed above the second material, thereby substantially encasing the STI structure in nitride. This provides a taller STI structure that results in a better fin profile during a subsequent fin reveal process.

Claim (Index 4):
The device in accordance with  claim 1  wherein the first dielectric material and the third dielectric material each comprise oxide, and the second dielectric material comprises nitride.
