Abstract:
Various embodiments of the present application are directed towards an edge-exposure tool with a light emitting diode (LED), as well as a method for edge exposure using a LED. In some embodiments, the edge-exposure tool comprises a process chamber, a workpiece table, a LED, and a controller. The workpiece table is in the process chamber and is configured to support a workpiece covered by a photosensitive layer. The LED is in the process chamber and is configured to emit radiation towards the workpiece. A controller is configured to control the LED to expose an edge portion of the photosensitive layer, but not a center portion of the photosensitive layer, to the radiation emitted by the LED. The edge portion of the photosensitive layer extends along an edge of the workpiece in a closed path to enclose the center portion of the photosensitive layer.

Claim (Index 1):
A method for edge exposure, the method comprising:\n receiving a workpiece covered by a photosensitive layer; exposing an edge portion of the photosensitive layer, but not a center portion of the photosensitive layer, to radiation generated by a light emitting diode (LED), wherein the edge portion of the photosensitive layer extends along an edge of the workpiece in a closed path to enclose the center portion of the photosensitive layer; and exposing an interior portion of the photosensitive layer to the radiation without exposing the center portion of the photosensitive layer, wherein the interior portion of the photosensitive layer is surrounded by the center portion of the photosensitive layer, and wherein the workpiece is at a same location during the exposing of the edge portion of the photosensitive layer as during the exposing of the interior portion of the photosensitive layer.
