A stepper or wafer stepper is a device used in the manufacture of integrated circuits (ICs). It is an essential part of the process of photolithography , which creates millions of microscopic circuit elements on the surface of silicon wafers out of which chips are made.
A stepper motor, also known as step motor or stepping motor, [1] is a brushless DC electric motor that rotates in a series of small and discrete angular steps. [2] Stepper motors can be set to any given step position without needing a position sensor for feedback. The step position can be rapidly increased or decreased to create continuous ...

Ultratech Stepper, Inc., was founded in 1979 by Leo de Bos, located in Santa Clara, California. The product line consisted of 1x microlithography steppers, using a unique catadioptric lens design. Until 1992, Ultratech Stepper, Inc., was a subsidiary of General Signal. Previous presidents included Leo de Bos and George Rutland.
Lavet-type stepping motor of a quartz clock. A black rotor sprocket provides the mechanical output.. The Lavet-type stepping motor has widespread use as a drive in electro-mechanical clocks [1] and is a special kind of single-phase stepping motor.

On a two-motion selector, as a digit was dialed, the wipers would step up the banks, then automatically rotate (self-step) into the selected bank until they found an "unused" outlet to the next switch stage. The last two digits dialed would operate the connector switch (final selector in Britain). The second to last digit would cause the wipers ...
