Photomasks as basic key elements
product detail
Product Description
Large-scale: photomasks as key elements within the semiconductor industry.
Photomasks continue to be key elements within the semiconductor industry. They are used mainly in wafer steppers (mask projection lithography) or in the mask aligner (masked ion beam lithography) for the production of integrated circuits (microchips).
The choice of the substrate depends largely on the intended end use. For environments with major fluctuations in temperature, for example, substrates with low thermal expansion coefficients are used.
