Webmask aligner have been sold since then, until the MJB3 was finally replaced by the MJB4 in 2004. Projection lithography pushed mask aligner . lithography out of semiconductor front-end in the early 1980s. However, mask aligner lithography was never phased-out. The installed mask aligners remained in operation for less critical layers.

Lithographic photomasks are typically transparent fused silica plates covered with a pattern defined with a chromium (Cr) or Fe2O3 metal absorbing film. Photomasks are used at wavelengths of 365 nm, 248 nm, and 193 nm. Photomasks have also been developed for other forms of radiation such as 157 nm, 13.5 … Meer weergeven A photomask is an opaque plate with transparent areas that allow light to shine through in a defined pattern.
