Abstract
A method by using positive photoresist to form narrow aperture width IC, it includes: Semiconductor substrate; Form insulating layer on semiconductor substrate. Form reflection layer, which reflectivity is larger than insulating layer, on insulating layer. Form flat-coating positive photoresist on reflection layer. Through exposure point to expose the flat-coating positive photoresist into exposed flat-coating positive photoresist. Develop exposed flat-coating positive photoresist into positive photoresist etching photomask pattern.
