Innovation and investment in the future are hallmarks of Gersteltec's approach

SU-8 photoresist is based on an epoxy resin developed by IBM. SU-8 is a thick, near-UV photoresist technology through i-line, and has advantages for the semiconductor industry as well as for microtechnologies and nano applications.

SU-8 is used in the development of MEMS, MOMES, UV-LIGA microfabrication and coatings. SU-8 can be patterned by several lithography techniques, such as X-ray, UV and e-Beam.

SU-8 is specifically used for applications requiring high aspect ratios in very thick layers with vertical sidewall profiles.
