Applied Explains: Photomask Technology for the EUV Era

Photomasks, as regular readers of this blog may recall, are the blueprints used for making chips. The photolithography process prints the patterns etched on the mask onto silicon wafers to define transistors, memory cells and wiring – all the nanoscale structures that make up a functional device.Lithography is expected to undergo a seismic shift over the next few years as the industry adopts a new technology called extreme ultraviolet lithography, or EUV for short. This change requires a new generation of photomasks featuring new materials and operating principles.
