Top
Products

PIX-1400/3400 are non-photosensitive polyimide precursors with self-adhesive properties to SiN, SiON, and SiOx. PIX series can protect the passivation layer and metal layer by applying it on the IC chip surface. This product does not have photosensitivity, it is possible to form patterns using a positive photoresist process using a positive photoresist and an aqueous solution of TMAH.
