The author(s) have declared they have no conflict of interest with regard to this content. The resin is photosensitized as much as 10 wt % of the resinmass with triarylsulfonium salt, such as the CYRACUREUVI (Union Carbided) with peaks of UV light absorption at310 and 230 nm, allowing protolysis in the wavelength rangeof conventional broadband mask aligners. SU-8 can be patterned by several lithography techniques, such as X-ray, UV and e-Beam. Here we demonstrate a fast, reproducible, and comparatively gen- 5. applications of SU-8. 
SU-8 is used in the development of MEMS, MOMES, UV-LIGA microfabrication and coatings. The main component of the resist is EPON SU-8 resin (Shell Chemical), which is dissolved in an organic solvent [gamma-butyrolacton (GBL)].
