Abstract:
A method includes etching a semiconductor substrate to form trenches, with a portion of the semiconductor substrate between the trenches being a semiconductor strip, and depositing a dielectric dose film on sidewalls of the semiconductor strip. The dielectric dose film is doped with a dopant of n-type or p-type. The remaining portions of the trenches are filled with a dielectric material. A planarization is performed on the dielectric material. Remaining portions of the dielectric dose film and the dielectric material form Shallow Trench Isolation (STI) regions. A thermal treatment is performed to diffuse the dopant in the dielectric dose film into the semiconductor strip.

Claim (Index 2):
The method of  claim 1 , wherein the forming the dielectric dose film comprises:\n depositing a blanket dose film; and etching upper portions of the blanket dose film on a top surface and sidewalls of the semiconductor strip, with lower portions of the blanket dose film remaining as the dielectric dose film, and the thermal treatment is performed on the blanket dose film that has been etched.
