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 8):
A structure comprising:\n a semiconductor substrate; a first Shallow Trench Isolation (STI) region extending into the semiconductor substrate, the first STI region comprising:\n a first liner dielectric layer contacting the semiconductor substrate; \n a first dielectric region over a bottom portion of the first liner dielectric layer, the first dielectric region being between opposite sidewall portions of the first liner dielectric layer; and \n a second dielectric region extending into the first dielectric region, the second dielectric region being different from the first dielectric region; \n a second STI region extending into the semiconductor substrate, the second STI region comprising:\n a second liner dielectric layer contacting the semiconductor substrate; \n a third dielectric region over a bottom portion of the second liner dielectric layer, the third dielectric region being between opposite sidewall portions of the second liner dielectric layer, wherein the third dielectric region and the first dielectric region are formed of a same dielectric material; and \n a dielectric layer comprising:\n a first portion over and contacting both the first dielectric region and the second dielectric region; and \n a second portion, wherein the second portion of the dielectric layer has a first end and a second end extending to opposite sidewall portions of the second liner dielectric layer, and an entirety of the second portion of the dielectric layer is in contact with the third dielectric region.
