Claim Text:
1. A system for processing at least one section of a thin film sample on a substrate, comprising: a processing arrangement, which when executing a computer program, is configured to perform the following steps: (a) controlling an irradiation beam generator to emit successive irradiation beam pulses at a predetermined repetition rate, (b) controlling a shaping of each of the irradiation beam pulses to define at least one line-type beam pulse, wherein a profile of each of the line-type beam pulses includes a top portion, a leading portion and a trailing portion, the at least one line-type beam pulse being provided for impinging the film sample; (c) controlling an irradiation of a first portion of the film sample with at least the top portion of a first one of the line-type beam pulses, to at least partially melt the first portion, the irradiated first portion being allowed to resolidify and crystallize to form approximately uniform areas therein, and (d) after step (c), controlling an irradiation of a second portion of the film sample with at least the top portion of a second one of the line-type beam pulses to at least partially melt the second portion, the irradiated second portion being allowed to resolidify and crystallize to form approximately uniform areas therein, wherein the processing arrangement controls an emission of the second one of the line-type beam pulses to immediately follow an emission of the first one of the line-type beam pulses, wherein at least one section of the first portion of the film sample is prevented from being irradiated by the trailing portion of the second one of the line-type beam pulses.
