Patent ID: 8796769

Claim:
An apparatus for linearly focused annealing of buried species comprising: an electromagnetic radiation source; a stage having dimensions adapted for accommodating a semiconductor substrate within a chamber; an optical element disposed between the electromagnetic radiation source; and a controller coupled to the electromagnetic radiation source, the controller comprising machine readable program instructions or instruction logic that allow the controller to control a depth into which a substrate is exposed to the radiation, a species source to introduce a species into the substrate; and wherein the controller is configured to: translate linearly focused electromagnetic radiation continuously across a device side surface of the substrate in a first direction for a period of time sufficient to thermally influence the species to react with the semiconductor material within the substrate, wherein the electromagnetic radiation is focused from only one single continuously emitting electromagnetic radiation source to continuously extend linearly across a total diameter of the substrate in a form of a single continuously emitted line in a second direction different than the first direction during translating, and wherein during translating, the continuously emitted line comprises a laser that extends across the entire width of a wafer.
