Abstract:
1. A method of processing a thin film, comprising: (a) generating a plurality of laser beam pulses using a laser source having energy beam characteristics; (b) directing a first generated laser beam pulse from the laser source onto a first optical path, wherein said first optical path includes at least one optical element; (c) modulating said energy beam characteristics of said first optical path-directed laser beam pulse via said at least one optical element of said first optical path; (d) irradiating at least a portion of a first region of said thin film with said first optical path-directed laser beam pulse to induce melting and a subsequent crystallization of said portion of said first region; (e) directing a second generated laser beam pulse from the same laser source onto a second optical path, wherein said second optical path includes at least one optical element; (f) modulating said energy beam characteristics of said second optical path-directed laser beam pulse via said at least one optical element of said second optical path, wherein said energy beam characteristics of said second optical path-directed laser beam pulse is different from said energy beam characteristics of said first optical path-directed laser beam pulse; and (g) irradiating at least a portion of a second region of said thin film with said second optical path-directed laser beam pulse to induce melting and a subsequent crystallization of said portion of said second region.
