Abstract:
A method for forming a semiconductor device is provided. A first patterned mask is formed on the substrate, the first patterned mask having a first opening therein. A second patterned mask is formed on the substrate in the first opening, the first patterned mask and the second patterned mask forming a combined patterned mask. The combined patterned mask is formed having one or more second openings, wherein one or more unmasked portions of the substrate are exposed. Trenches that correspond to the one or more unmasked portions of the substrate are formed in the substrate in the one or more second openings.

Claim (Index 1):
A method comprising:\n forming a patterned sacrificial layer over a substrate, the patterned sacrificial layer having a first opening exposing the substrate; depositing a first mask layer over the patterned sacrificial layer and in the first opening; etching the first mask layer to form a first patterned mask, the first patterned mask having a second opening exposing the substrate; depositing a second mask layer over the first patterned mask and in the second opening; etching the second mask layer to form a second patterned mask; removing the first patterned mask, the second patterned mask and the patterned sacrificial layer remaining after the removing; and etching trenches in the substrate using the second patterned mask and the patterned sacrificial layer as a combined mask.
