WebFPA-5550iZ2 steppers provide the highest productivity & overlay accuracy among i-line Lithography Equipment. Canon has achieved the *highest level of productivity (throughput) among all equivalent class i-line Lithography Equipment. FPA-5550iZ2 steppers optimize alignment, exposure & wafer transfer sequences, shorten wafer lot exchange times ... A single iteration of photolithography combines several steps in sequence. Modern cleanrooms use automated, robotic wafer track systems to coordinate the process. The procedure described here omits some advanced treatments, such as thinning agents or edge-bead removal. The photolithography process is carried out by the wafer track and stepper/scanner, and the wafer track syste…

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.
