Patent ID: 7897522

Claim:
A method for particle beam lithography, comprising: forming a plurality of cell patterns on a stencil mask for manufacturing of a semiconductor device and shaping at least one of the plurality of cell patterns with a first polygonal-shaped contour, wherein the act of shaping the at least one of the plurality of cell patterns comprises determining a plurality of cell primitives which are known to be characterized by being capable of being stencil-masked to increase reuse of the plurality of cell primitives for manufacturing of the semiconductor device; exposing a first polygonal-shaped cell pattern on the stencil mask to a particle beam so as to project the first polygonal-shaped cell pattern on a substrate; and exposing at least a part of a second polygonal-shaped cell pattern on the stencil mask, having a second contour, to the particle beam, wherein the second contour is used to produce a second image that mates with a first image produced by using the first polygonal-shaped contour of the first polygonal-shaped cell pattern.
