Photo Mask Processor

Print and develop working photo mask plates.

What does a Photo Mask Processor do?

Prints and develops working photo mask plates from master plate for subsequent use in fabrication of semiconductor devices: Reads work order to determine process specifications. Loads unexposed plates and master plate in holding fixture of printing machine. Adjusts controls and activates machine that exposes blank plates to image on master plate. Develops exposed plates, using developing equipment, chemicals, and dryer. Cleans developing equipment periodically and refills chemicals in developing sinks. Cleans master plate at specified intervals, using cleaning and rinsing solutions and ultrasonic equipment.
