Abstract
In one illustrative embodiment, the method comprises initiating a develop process on a layer of photoresist formed above a wafer, indicating an endpoint of the develop process, determining a duration of the endpoint develop process, and determining if the determined duration of the develop process is not within a preselected range. In another aspect, the present invention is directed to a system that comprises a develop station for performing a develop process on a layer of photoresist formed above a wafer, a develop endpoint detector for indicating an endpoint of the develop process, and a controller for determining if a duration of the develop process is not within a preselected range.
