Lithography hard mask materials

WebAbsorber. The masking layer on a photomask is a very thin metallic coating. Popular absorbers in use today are chromium, aluminum, iron oxide, titanium, and silver-halide emulsion. While standard chrome is the work-horse for most photolithography, there are many variations of the oxide thickness on top. Web“The primary application of EUV lithography at 7nm will be for contact, via and cut layers,” Levinson noted. “It will be important to enable EUVL for metal masks at the 5nm node, which increases the need for an ample supply of very low defect EUV mask blanks.”
