Description

This video describes the Ultratech Model 900 Projection Stepper, a key piece of semicondcutor manufacturing equipment, released in 1982. A stepper is used to transfer circuit patterns contained on a master template to silicon wafers, which are then cut into individual circuit die and packged for sale.

Key members of the Model 900 design team include Martin Lee, Ron Voisin, Ron Hershel, and Rusty Wells.

The Model 900 could accomodate 3”, 4” 5” and 6” wafers and used electron beam lithography. With 4” wafers, the stepper could produce up to 35 wafers per hour, with a one micron feature size. The video discusses return on investment by compairing the Model 900 with a competitor (GCA) and concludes with a promotional segment on Ultratech’s parent company, General Signal.
