发明名称 Digital light valve
摘要 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. For example, the method may sequentially expose adjacent areas of semiconductor film to gated light in a first direction; and, simultaneously exposing adjacent areas of semiconductor film to gated light in a second direction, different than the first direction. For example, the second direction may be perpendicular to the first direction. As a result, crystal grains can be laterally grown simultaneously in the first and second directions.
