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 17):
A method comprising:\n forming a patterned sacrificial layer covering a first region of a substrate; forming a first patterned mask covering a second region of the substrate without using photolithography; forming a second patterned mask covering a third region of the substrate without using photolithography; removing the first patterned mask to expose the second region of the substrate; etching the second region of the substrate to form trenches in the substrate; and forming semiconductor devices from portions of the substrate between neighboring trenches.
