Information the Equipment Can Provide

The Suss MA6 mask aligner provides several modes of contact that can be selected when exposing a photoresist coated wafer to the UV light source. Contact can be light, heavy or vacuum assisted. Additionally, the user may expose with no contact at all using special mask holders equipped with precision machined stand-off flags. The 350W lamp provides even illumination with computer-controlled intensity modulation to produce reliable exposures.


  • Lithography feature resolution of 1 μm readily achieved
  • Mask holders for 4″, 5″ and 7″ square masks
  • Substrate holders for 3, 4- and 6-inch wafers
  • Substrate thickness up to 0.25″ allowed
