Equipment for lithography (pattern definition)

EVG 620 double-sided mask aligner

The mask aligner is used to transfer a pattern to a photosensitive material by selective exposure (through a mask) from a UV radiation source. The equipment supports several modes (proximity, soft/ hard/vacuum contact) and can also do bottom side alignment. It can also be used in nano-imprint mode, where the pattern is transferred by imprinting.
