Abstract:
1. A process for processing a silicon thin film on a sample, comprising the steps of: (a) controlling an irradiation beam generator to emit irradiation beam pulses at a predetermined repetition rate; (b) separating file irradiation beam pulses into a first set of separated beam pulses and a second set of separated beam pulses; (c) forwarding the first set of separated beam pulses to irradiate and pass at least portions thereof through a mask to produce a plurality of beamlets; and (d) providing the second set of separated beam pulses and the beamlets to impinge and irradiate at least one section of the silicon thin film, wherein, when the second set of separated beam pulses and the beamlets simultaneously irradiate the at least one section of the silicon thin film, the second set of the separated beam pulses and the beamlets provide a combined intensity which is sufficient to melt the at least one irradiated section of the silicon thin film throughout an entire thickness of the section.
