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 10):
An edge-exposure tool comprising:\n a process chamber; a workpiece table in the process chamber, wherein the process chamber is configured to support a workpiece covered by a photosensitive layer; a light emitting diode (LED) in the process chamber, wherein the LED is configured to emit radiation towards the workpiece; a first lens having a light-receiving surface and a light-emitting surface on opposite sides of the first lens and respectively facing the LED and the workpiece table, wherein the first lens is configured to receive the radiation at the light-receiving surface; and a controller 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, 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.
