ABSTRACT:
The present disclosure is directed to methods and systems for processing a thin film samples. In an exemplary method, semiconductor thin films are loaded onto two different loading fixtures, laser beam pulses generated by a laser source system are split into first laser beam pulses and second laser beam pulses, the thin film loaded on one loading fixture is irradiated with the first laser beam pulses to induce crystallization while the thin film loaded on the other loading fixture is irradiated with the second laser beam pulses. In a preferred embodiment, at least a portion of the thin film that is loaded on the first loading fixture is irradiated while at least a portion of the thin film that is loaded on the second loading fixture is also being irradiated. In an exemplary embodiment, the laser source system includes first and second laser sources and an integrator that combines the laser beam pulses generated by the first and second laser sources to form combined laser beam pulses. In certain exemplary embodiments, the methods and system further utilize additional loading fixtures for processing additional thin film samples. In such methods and systems, the irradiation of thin film samples loaded on some of the loading fixtures can be performed while thin film samples are being loaded onto the remaining loading fixtures. In certain exemplary methods and systems, the crystallization processing of the semiconductor thin film samples can consist of a sequential lateral solidification (SLS) process.
