This Researchers have been struggling for two decades with this problem, and al- By using Gersteltec Striper A you can remove the SU8 without caused any damage to yours metals like Ni, Ni/Fe, Au, Cu. The author(s) declare that they have sought and gained approval from the relevant ethics committee/IRB for this research and its publication.

SEM Images show dark regions (exposed region)along the thickness of the SU-8 film. 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. The author(s) have declared they have no conflict of interest with regard to this content.
