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 6):
The device in accordance with  claim 5  wherein the second STI layer and the one or more sidewall spacers comprise nitride, and the third STI layer is substantially encased in nitride corresponding to the second STI layer, the middle portion of the third STI layer, and the at least one sidewall spacer.
