Abstract:
Negatively sloped isolation structures are formed on a semiconductor substrate to isolate devices from one another. The negatively sloped isolation structures have a top critical dimension which is smaller than a bottom critical dimension. The negatively sloped isolation structures may penetrate through an insulator layer of a silicon-on-insulator structure arrangement.

Claim (Index 1):
A method comprising:\n patterning a mask over a semiconductor layer, the semiconductor layer being disposed over a substrate; etching a trench in the semiconductor layer through the mask, wherein the trench has a top opening having a first width and a bottom having a second width, wherein the second width is greater than the first width, wherein the top opening is aligned to an upper surface of the semiconductor layer, and wherein sidewalls of the trench slope outwardly from the top opening to the bottom; and depositing an insulating material in the trench, wherein a sidewall of the insulating material flares from the first width to the second width.
