A cup wash disk for cleaning a photoresist process tool is provided. An upper plate is arranged over a lower plate to define a cavity between the upper and lower plates. The lower plate comprises peripheral openings in fluid communication with the cavity and arranged along a periphery of the lower plate. A plurality of shims is arranged between the upper and lower plates to space the upper and lower plates and to define slits between the upper and lower plates. The slits are in fluid communication with the cavity. A method for cleaning the photoresist process tool using the cup wash disk is also provided.

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.
