Abstract:
A lithography method to pattern a first semiconductor wafer is disclosed. An optical mask is positioned over the first semiconductor wafer. A first region of the first semiconductor wafer is patterned by directing light from a light source through transparent regions of the optical mask. A second region of the first semiconductor wafer is patterned by directing energy from an energy source to the second region, wherein the patterning of the second region comprises direct-beam writing.
