PLG / Photolithography

Tools
(1) SÜSS MicroTec MA6/BA6&(2) KARL SÜSS MJB3 Mask Aligners

Applications
Pattern transfer of a photomask to a UV light-sensitive material (photoresist) deposited onto rigid or flexible substrates. UV exposure is performed using a Mask Aligner that allows high precision mask-to-sample alignment. Dissolution of the exposed (positive tone photoresist) or unexposed (negative tone) regions of the photoresist results in the engraving of the mask pattern or its reverse into the photoresist. Photoresist patterning is widely used for the development of Microelectronic / Photonic devices and Microsystems.
