Patent number: 7682948Abstract: A system and method are provided for crystallizing a semiconductor film using a digital light valve. The method comprises: enabling pixel elements from an array of selectable pixel elements; in response to enabling the pixel elements, gating a light; sequentially exposing adjacent areas of a semiconductor film, such as Si, to the gated light; annealing the light-exposed areas of semiconductor film; and, in response to the annealing, laterally growing crystal grains in the semiconductor film.
