Is this remover available with AZ 5214E which is an IR photo-resist (positive to negative) ?
1 answer-
The photoresist remover AZ 5214E (or others options for positive and negative removal) is not available. Unfortunately, the 651761, which is also included in the Negative Photoresist kit (654892), are the only reagents offered at this time.
