WebThe proximity mask is necessary to reduce the diffraction which increases the lifetime of mask pattern. The typical line width of 0.25-0.15 pm can be resolved using X-ray lithography with proximity mask. The main advantages of X-ray lithography are the fragility and dimensional instability of the mask and the complex alignment system. WebRolling Mask Lithography – RML ®.

There is not only one-way to do a plastic photomask, as there is not only one-way to imprint. The resolution of the photomask is the same of the printer and classically around 10µm. There are several kinds of soft photomasks ...
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.
