Abstract

A method includes transferring a wafer into a first processing chamber by using a robot arm mechanism, and applying a photoresist on the wafer in a first processing chamber. The wafer is transferred from the first processing chamber into a second processing chamber by using the robot arm mechanism, and the photoresist is exposed to a pattern of light in the second processing chamber. The method includes transferring the wafer from the second processing chamber into a third processing chamber by using the robot arm mechanism, and developing the exposed wafer in the third processing chamber. The method includes cleaning the robot arm mechanism in a dummy chamber.
