water-based developer

This water repellent layer prevents the aqueous developer from penetrating between the photoresist layer and the wafer's surface, thus preventing so-called lifting of small photoresist structures in the (developing) pattern.

Excellent developability: Research and development carried on at the Lastra Group laboratories resulted in the formulation of an environmentally safe diazo/photopolymer coating which is processed in a biodegradable, aqueous developer.
