Photo Mask Pattern Generator

Operate pattern-generating machines to transfer circuit patterns.

What does a Photo Mask Pattern Generator do?

Operates pattern-generating machine to transfer integrated circuit pattern onto surface of reticle for use by PHOTO MASK PROCESSOR 976.384-014 in production of photo mask plates used in fabrication of semiconductor devices: Reads specifications to determine production data and enters data into pattern-generating machine, using keyboard. Loads digitizer tape into machine reader to control exposure process. Positions unexposed photoresist coated reticle on projection stage of machine and adjusts focus. Types commands to activate machine that exposes photoresist on reticle to circuit pattern. Tends developing and etching equipment to develop and etch pattern on reticle. Inspects reticle for defects, using microscope.
