Multiple mask lithography
Multiple mask lithography
Photolithography is a technique that transfers a pattern from a photomask to a substrate coated with a light-sensitive material called photoresist. The pattern is created by exposing the photoresist to light from a source through the mask, and then developing it in a solution. The substrate can then undergo other processes such as deposition or etching. Some devices may require multiple photolithography steps with different masks, which need to be aligned precisely to the previous layers. For this purpose, mask aligners are used to ensure accuracy and control the exposure conditions.

Mask aligner used for 4 inch/100mm wafers,Intensity 2-4 mW/cm2 in I-line mode. The MA-6 mask aligner operates in I-line mode currently only on 100mm or 4” wafers. Under ideal circumstances with very clean substrates and masks, we have printed sub 0.5um features on this system, but its resolution is essentially limited by substrate quality.
