AZ® P4000 Series Photoresists

AZ P4000 Series Photoresists are general purpose i-line/h-line/g-line sensitive materials engineered for performance in most electro-plating and other metal deposition process environments. AZ P4000 resists exhibit excellent adhesion to metal seed layers and compatibility with nearly all plating solutions including gold-cyanide. Plating bath lives are maximized thanks to P4000's unique PAC chemistry which prevents leaching of the DNQ. Coated thickness range is approximately 1.0 to 9µm (single coat). Optimized for the AZ 400K developers (AZ 400K 1:4 or AZ 400K 1:3) or AZ 421K developer. MIF developers not recommended.
