Abstract:
Anti-reflective compostions are prepared from cellulosic binders and alkylat ed aminoplast cross-linking agents derived from melamine, urea, benzoguanamine or glycoluril. These compositions are used to form bottom anti-reflective layer s with high plasma etch selectivity when used in multilayer photoresist processes.
