SYSTEMS AND METHODS FOR INDUCING CRYSTALLIZATION OF THIN FILMS USING MULTIPLE OPTICAL PATHS

摘要

The present invention is directed to systems and methods for irradiating regions of a thin film sample(s) with laser beam pulses having different energy beam characteristics that are generated and delivered via different optical paths. An exemplary method includes generating laser beam pulses having energy beam characteristics, directing a first pulse onto a first optical path, modulating the pulse's energy beam characteristics, and irradiating at least a portion of a first region of the thin film with the pulse to induce crystallization of the portion of the first region. The method also includes directing a second pulse onto a second optical path, modulating the pulse's energy beam characteristics so as to be different from the energy beam characteristics of the first pulse, and irradiating at least a portion of a second region of the thin film with the second pulse to induce crystallization of the portion of the second region.
