Polymer, resist protective coating material, and patterning process
摘要:
In an immersion lithography process, a pattern is formed by forming a photoresist layer on a wafer, forming a protective coating on the photoresist layer from an overlay material, exposing the layer structure to light in water, and developing. A water-insoluble, alkali-soluble material is used as the overlay material.
