Technology Description:

 

The mask aligner is out of order as such, but can be used as an XY-stage for specialised purposes.

Maskaligners are used in photolithography to transfer a pattern on a photomask to a photoresist on a wafer. This photoresist can then serve as e.g. an etch mask to transfer the pattern into the wafer. The photoresist can also be removed after metal deposition, leaving a metal pattern on the wafer (lift-off).Soft and hard contact exposures give a resolution of 1-2 µm. Vacuum contact exposure give higher resolution (0,6 µm) but shortens the mask lifetime, whereas proximity exposures give lower resolution but less wear on the mask
