Toray STF-2000 photosensitive polyimide enables fine patterning with 30μm line widths in films up to 200μm thick. Supports aspect ratios up to 7 using high-sensitivity negative-tone formulation and proprietary photoresist design. Maintains polyimide advantages – heat, chemical and X-ray resistance – while eliminating NMP and PFAS for reduced environmental impact. Offers alkaline development process, single-step thick-film patterning and high-resolution imaging for MEMS and electronics applications.
