Patent ID: 7311778

Claim:
A system for processing a film on a substrate, comprising: a laser for generating a plurality of laser beam pulses having a repetition frequency; a film support for positioning a film that is capable of movement in at least one direction; a mask support for positioning a mask that is capable of movement in at least one direction; optics for directing the plurality of laser beam pulses through a mask to generate patterned laser beams; optics for directing the patterned beams onto a region of the film; and a controller for controlling the movement of the film support and the mask support in conjunction with the frequency of the laser beam pulses, wherein the controller comprises computer-implemented instructions for executing the steps of: positioning the film and the mask so as to irradiate a portion of a selected region of a film with one of the plurality of patterned laser beams; and moving the film along a first translation pathway and moving the mask along a second translation pathway such that successive portions of the selected region are irradiated with patterned beams, and such that the selected region of the film is substantially completely crystallized in a single traversal of the patterned beams over the selected region of the film.
