AZ nLoF 2000 Series Spin Curves

AZ® nLoF™ 2000 Series Photoresists

AZ nLoF 2000 Series photoresists are negative tone materials designed for single layer lift-off and RIE etch processing. Ideal lift-off profiles are achieved with a simple bake, expose, PEB and develop process sequence; no under layers required. Side wall angles are process tunable from strong retro-grade for lift-off, to 90 degrees vertical for RIE. Removal is easy with standard photoresist strippers. Coated film thickness range is 1.8 to 10µm. (AZ 300MIF or AZ 726MIF recommended)
