Lithography stepper
Steppers are an essential part of the complex process, called photolithography, which creates millions of microscopic circuit elements on the surface of silicon wafers out of which chips are made. These chips form the heart of ICs such as computer processors, memory chips, and many other devices. Meer weergeven A stepper is a device used in the manufacture of integrated circuits (ICs) that is similar in operation to a slide projector or a photographic enlarger. Stepper is short for step-and-repeat camera. Steppers are an essential … Meer weergeven Integrated circuits (ICs) are produced in a process known as photolithography. The process starts with a large highly purified … Meer weergeven The silicon wafers are coated with photoresist, and placed in a cassette or "boat" that holds a number of wafers.
