发明名称 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. Exemplary methods include the steps of generating a plurality of laser beam pulses having energy beam characteristics, directing a generated laser beam pulse onto a first optical path, modulating the energy beam characteristics of the first optical path-directed laser beam pulse, irradiating at least a portion of a first region of the thin film with the first optical pathdirected laser beam pulse to induce crystallization of the portion of the first region, directing a generated laser beam pulse onto a second optical path, modulating the energy beam characteristics of the second optical path-directed laser beam pulse, wherein the energy beam characteristics of the second optical path-directed laser beam pulse is different from the energy beam characteristics of the first optical path-directed laser beam pulse, and irradiating at least a portion of a second region of the thin film with the second optical path-directed laser beam pulse to induce crystallization of the portion of the second region. An exemplary system includes a first optical path, a second optical path, a beam steering element for directing laser beam pulses onto the first optical path and the second optical path; and a handling stage for controlling the position of a thin film relative to the laser beam pulses being directed via the first and second optical paths.
