Abstract:
A system and method for providing electrical isolation between closely spaced devices in a high density integrated circuit (IC) are disclosed herein. An integrated circuit (IC) comprising a substrate, a first device, a second device, and a buried trench in the substrate and a method of fabricating the same are also discussed. The buried trench is positioned between first and second devices and may be filled with dielectric material. Alternatively, the buried trench contains air. A method of using Hydrogen annealing to create the buried trench is disclosed.

Claim (Index 18):
An isolation structure, comprising:\n a trench formed within a substrate; a dielectric layer filling at least a bottom portion of the trench; and a seed layer disposed over a top surface of the dielectric layer and a top surface of the substrate, wherein the seed layer is configured to smooth a reshaping of the substrate over the dielectric layer.
