MEGAPOSITSPR220i-linephoto- resist is an optimized general-pur- pose, multi-wavelength resist designed to cover a wide range of film thicknesses, 1-30 μm, with a single-coat process. MEGAPOSITSPR220photoresistalsohas excellent adhesion and plating characteri- stics, which make it ideal for such thick film applications as MEMS and bump process.
