Abstract:
1. A device for processing a substrate comprising: a laser configured to produce laser light, the laser configured to have a high energy mode and a low energy mode, the high energy mode configured to produce light energy sufficient to completely melt a silicon film, and the low energy mode configured to produce light energy that is not sufficient to completely melt a silicon film; beam shaping optics coupled to the laser and configured to convert the laser light emitted from the laser into a long thin beam with a short axis and a long axis; a stage configured to support the substrate and film; and a translator coupled with the stage, the translator configured to advance the substrate and film so as to produce a step size in conjunction with the firing of the laser, wherein the translator and the firing of the laser are configured to produce a smaller step size in the low energy mode when compared to the step size of the high energy mode.
