Patent ID: 8906725

Claim:
A method of treating a substrate, comprising: Identifying a first treatment zone; forming a molten area of the first treatment zone by exposing a surface of the first treatment zone to a first laser pulse, wherein the first laser pulse has a non-uniformity of less than about 5 percent; recrystallizing the molten area of the first treatment zone while exposing the first treatment zone to a plurality of laser pulses; identifying a second treatment zone; and repeating the forming a molten area and the recrystallizing the molten area with the second treatment zone, wherein the forming a molten area of each treatment zone further comprises exposing the surface of each treatment zone to a second laser pulse, and a duration between the first laser pulse and the second laser pulse is less than a time necessary for a portion of the molten area to refreeze, and wherein the first laser pulse and the second laser pulse have the same duration and intensity.
