Patent ID: 8288683

Claim:
A dynamic surface anneal apparatus for annealing a semiconductor workpiece, said apparatus comprising: a workpiece support for supporting a workpiece; an optical source; scanning apparatus for scanning said optical source and said workpiece support relative to one another along a fast axis; wherein said optical source comprises: an array of laser emitters arranged generally in successive rows of said emitters, said rows being transverse to said fast axis; plural collimating lenslets overlying respective ones of said rows of emitters and having a collimation direction along said fast axis; a fast axis optical deflection element associated with selected ones of said rows of emitters and having an optical deflection angle corresponding to a beam deflection along said fast axis for said selected rows of emitters; and optical apparatus for focusing light from said array of laser emitters into a narrow line beam on a surface of said workpiece along a direction transverse to said fast axis.
