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 19):
The method of  claim 15 , wherein the thermal treatment comprises a furnace anneal performed at a temperature between about 400\u00b0 C. and about 700\u00b0 C., with the thermal treatment lasts between about 20 minutes and about 5 hours.
