FIELD: micro-electronics, in particular, method for producing mask templates.
SUBSTANCE: for increasing adhesion of photoresists to masking layers of chromium and iron oxide, 2-3% mass. Of leucoparafuchsin (amine derivative of tritane), which allows, after appropriate thermal processing, to improve precision of reproduction of critical elements of integration circuit, undercutting below resist film not exceeding 0,1 micrometers to the side.
EFFECT: increased efficiency.
