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 10):
A method comprising:\n etching a first trench and a second trench in a semiconductor substrate, the first trench separated from the second trench by a first device area of the semiconductor substrate; and depositing an insulating material in the first trench and in the second trench to form a first isolation structure and a second isolation structure, respectively, wherein an angle between a first sidewall of the first isolation structure and a top surface of the first isolation structure where the first sidewall adjoins the top surface of the first isolation structure is greater than 90 degrees, and wherein the top surface of the first isolation structure is level with or extends above an upper surface of the semiconductor substrate.
