Substantially transparent aqueous base soluble polymer system for use in 157 nm resist applications
TL;DR: Fluorocarbinol- and/or fluoroacid-functionalized silsesquioxane polymers and copolymers are provided in this paper, and a process for using the composition to generate resist images on a substrate is also provided, i.e., in the manufacture of integrated circuits or the like.

TL;DR: In this paper, a positive-tone bilayer resist system consisting of a thin silicon containing imaging layer over a recently developed crosslinked polymeric underlayer is presented, which is based on a dual-functional silicon containing monomer, tris(trimethylsilyl)silylethyl methacrylate, which in addition to providing etch resistance, also functions as acid sensitive functionality.
Proceedings ArticleDOI
