WebStep 4 – Transparent film photomask fabrication Process. The film is fed into the processor after imaging via a series of rollers, and undergoes some chemical changes through the development of the image. Development changes the exposed silver halide crystals into ‘black’ particles in the emulsion layer of the photomask.

The History of the Semiconductor Photomask - YouTube

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 … Meer weergeven A photomask is an opaque plate with transparent areas that allow light to shine through in a defined pattern. Photomasks are commonly used in photolithography for the production of integrated circuits (ICs or "chips") to … Meer weergeven Leading-edge photomasks (pre-corrected) images of the final chip patterns are magnified by four times.
