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 16):
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; an LED controller; an LED driver electrically coupled between the LED controller and the LED, wherein the LED driver is configured to regulate drive current to the LED in response to commands from the LED controller; and an exposure controller configured to provide the LED controller with a first command specific to a light source different than the LED, wherein the LED controller is configured to translate the first command into a second command specific to the LED, and to provide the second command to the LED driver, in response to receiving the first command; wherein the LED controller, the LED driver, and the exposure controller are independent of each other and are configured to expose a ring-shaped edge portion of the photosensitive layer, but not a center portion of the photosensitive layer, to the radiation.
