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 1):
A method comprising:\n forming a dielectric layer comprising a portion extending on a top surface of a semiconductor region, wherein the dielectric layer is un-doped with p-type and n-type dopants; depositing a dose film over the dielectric layer, wherein the dose film is formed of a dielectric material doped with a dopant of n-type or p-type; and performing a thermal treatment to diffuse the dopant in the dose film into the semiconductor region.
