Abstract:
A method includes etching a semiconductor substrate to form trenches extending into the semiconductor substrate, and depositing a first dielectric layer into the trenches. The first dielectric layer fills lower portions of the trenches. A Ultra-Violet (UV) treatment is performed on the first dielectric layer in an oxygen-containing process gas. The method further includes depositing a second dielectric layer into the trenches. The second dielectric layer fills upper portions of the trenches. A thermal treatment is performed on the second dielectric layer in an additional oxygen-containing process gas. After the thermal treatment, an anneal is performed on the first dielectric layer and the second dielectric layer.

Claim (Index 15):
A structure comprising:\n a semiconductor substrate; an isolation region extending into the semiconductor substrate, wherein the isolation region comprises:\n a first dielectric layer having a first reflective index; and \n a second dielectric layer over the first dielectric layer, wherein the first dielectric layer and the second dielectric layer comprise same types of elements, and the first dielectric layer and the second dielectric layer are configured to have different etching rates in response to an etching of the isolation region; and \n a gate dielectric contacting a top surface of the isolation region.
