The Karl Suss MA-6 mask aligner is used for high resolution photolithography. The mask aligner can perform precise alignment of plastic and hard chrome glass masks, both available for fabrication within the VINSE Cleanroom. Microscope top side alignment and video back side alignment are available for multi-layer photolithography fabrication.
