Patent ID: 8715412

Claim:
A system for processing a film comprising: a laser source configured to produce a pulsed laser beam; one or more optical elements configured to generate a first laser beam and a second laser beam having different beam characteristics from the pulsed laser beam, wherein the first laser beam has a first energy density to melt a first region of a film to be crystallized to form a first crystalline region having a first grain structure and the second laser beam has a second energy density sufficient to melt a second region of the film to be crystallized to form a second crystallized region having a second grain structure, wherein the first energy density is greater than the second energy density; a stage configured to support and position a film to be crystallized such that the first laser beam is directed to and irradiates a first portion of the stage and the second laser beam is directed to and irradiates a second portion of the stage; and a computer for controlling the laser source, optical elements, and stage to facilitate the delivery of the first laser beam and the second laser beam to portions of the stage corresponding to first and second regions of a film to be crystallized.
