Patent ID: 7804647

Claim:
A laser annealing mask with adjacent sections of fully resolved and sub-resolutional aperture patterns, the mask comprising: a first section with a plurality of first apertures and an opaque spacing between each first aperture, each first aperture having a first pattern shape that is sized for transmitting approximately 100% of incident light, fully resolved in a beam having the first aperture pattern shape, at a first energy density; a second section, located adjacent the first section, with a plurality of second apertures and an opaque spacing between each second aperture, each second aperture having a second pattern shape that is sized for transmitting approximately 100% of incident light, incompletely resolved in a diffracted beam having a blurred second aperture pattern shape; and, wherein the second aperture patterns each transmit a second energy density in the blurred second aperture pattern shape that is less than the first energy density.
