Abstract
The invention is a method for forming semiconductor devices from a substrate having a non-planar surface. An anti-reflection coating is formed between the substrate and photoresist layer to alleviate the problems caused by non-uniform reflection at the substrate surface during exposure of the photoresist layer. Three-layer and two-layer stacks are described for use with UV and i-line exposure.
