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.

Abstract: A method includes performing an implantation on a portion of a first layer to form an implanted region, and removing un-implanted portions of the first layer. The implanted region remains after the un-implanted portions of the first layer are removed. An etching is then performed on a second layer underlying the first layer, wherein the implanted region is used as a portion of a first etching mask in the etching. The implanted region is removed. A metal mask is etched using the second layer to form a patterned mask. An inter-layer dielectric is then etched to form a contact opening, wherein the patterned mask is used as a second etching mask.
