AZ 50XT Photoresist is a thick DNQ type resist optimized for MEMs and packaging (solder bump, etc.) applications. Single coat film thicknesses of 15 to 65µm are achievable on standard coating equipment. Superior adhesion to Cu substrates prevents under-plating and removal is easy using AZ 400T Stripper. Compatible with inorganic developers (AZ 421K or AZ 400K 1:3 recommended).
