Abstract
An apparatus for processing semiconductor wafers includes a single imaging stepper for exposing wafers processed on a first track and a second track. A method for processing semiconductor wafers includes selecting one of a first coater and a second coater for coating a first wafer with a photoresist. The coated wafer is exposed in a single stepper to form an exposed wafer. An operator selects one of a first developer and second developer to develop the exposed wafer.
