发明名称 Systems and methods for non-periodic pulse partial melt film processing
摘要 In one aspect, the present disclosure relates to a method of processing a thin film including, while advancing a thin film in a first selected direction, irradiating a first region of the thin film with a first laser pulse and a second laser pulse, each laser pulse providing a shaped beam and having a fluence that is sufficient to partially melt the thin film and the first region re-solidifying and crystallizing to form a first crystallized region, and irradiating a second region of the thin film with a third laser pulse and a fourth laser pulse, each pulse providing a shaped beam and having a fluence that is sufficient to partially melt the thin film and the second region re-solidifying and crystallizing to form a second crystallized region, wherein the time interval between the first laser pulse and the second laser pulse is less than half the time interval between the first laser pulse and the third laser pulse.
