Lithography mask polarity
Web20 jul. 2024 · In photolithography, it is common to imagine the photomask as a 2D screen with parts that block light and parts that transmit light. While this picture has its origins from long ago, it is no longer an accurate depiction in advanced lithography nodes, in particular for extreme ultraviolet lithography (EUVL) masks.

Masks for X-ray Lithography were typically made by e-beam direct write. 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 nm (EUV), X-ray, electrons, and ions; but these require entirely new …
