Abstract:
In a method for fabricating a semiconductor device, a trench is etched in a semiconductor substrate having a top surface, and a lining oxide layer is formed conformal to the trench. A negatively-charged liner covering the lining oxide layer and conformal to the trench is formed. The trench is partially filled with a flowable oxide to a level below the top surface of the semiconductor substrate, and the flowable oxide in the trench is cured. The negatively-charged liner above the cured flowable oxide is optionally removed. A silicon oxide is deposited in the remaining portion of the trench, and a planarization process is performed to remove excess portions of the silicon oxide over the top surface of the semiconductor substrate.

Claim (Index 14):
The method of  claim 10 , wherein partially filling the flowable oxide comprises filling the flowable oxide using a spin on glass (SOG) or flowable chemical vapor deposition (FCVD) process.
