The Heidelberg Instruments μPG 101 laser writer is a versatile micro pattern generation tool for direct writing/maskless lithography and low volume mask making of chrome-glass photolithography masks. The tool is compatible with a wide range of sample sizes, sample materials, and photoresists. The chrome-glass masks are compatible with the VINSE Karl Suss MA-6 mask aligner. All masks are printed by VINSE Cleanroom Staff unless otherwise specified.
