Lithographic processing
WebLithography is the process of transferring patterns of geometric shapes in a mask to a thin layer of radiation-sensitive material (called resist) covering the surface of a semiconductor wafer.

Webprocessing on 600 x 600mm2 panel over 300mm diameter wafer The tables demonstrate the productivity advantage of exposing on rectangular substrates versus circular wafers. In panel processing, the number of exposures per panel increases due to the larger area of the panel and processed panels per hour are less then processed wafers per hour.
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.
