Patent ID: 7906414

Claim:
A method for forming an electronic device on a semiconductor thin film, comprising: (a) providing the semiconductor thin film having a surface; (b) patterning a radiation beam into at least one beamlet in a pattern of beamlets, wherein each beamlet is incident on a target area of a first region of the semiconductor thin film; (c) irradiating the first region of the semiconductor thin film with a pulse of the patterned radiation beam, wherein each beamlet of the patterned radiation beam has sufficient fluence to melt semiconductor material in the target area on which it is incident, and wherein the molten semiconductor material in the target area recrystallizes when it is no longer exposed to the incident beamlet; (d) continuously translating the semiconductor thin film relative to the patterned radiation beam such that a second region of the surface of the semiconductor thin film is irradiated in the same manner as in (c), wherein the second region corresponds to a second area which is separate from a first area corresponding to the first region; and (e) forming the electronic device on at least the target area.
