Patent ID: 8507368

Claim:
A method for forming an electronic device on a semiconductor thin film, comprising: (a) providing the semiconductor thin film having a surface; (b) generating a radiation beam, wherein the beam 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 radiation beam, wherein the radiation beam pulse has a fluence sufficient to partially melt the semiconductor material in the target area on which it is incident, and wherein the partially molten semiconductor material in the target area recrystallizes when it is no longer exposed to the incidence beam; (d) continuously translating the semiconductor thin film relative to the radiation beam such that a second region of the surface of the semiconductor thin film is irradiated with a second radiation beam pulse having a fluence sufficient to partially melt the semiconductor material in the second region on which it is incident, and wherein the partially molten semiconductor material in the second region recrystallizes when it is no longer exposed to the incidence beam; wherein the second region corresponds to a second area which is adjacent to a first area corresponding to the first region; and (e) forming the electronic device in the target area.
