Abstract: A high-performance radiation sensitive silicon-containing negative-tone resist is provided along with a method of using the silicon-containing resist in multilayer, including bilayer, imaging for manufacturing semiconductor devices. The negative-tone silicon-containing resist is based on an acid catalyzed high-contrast crosslinking of aqueous base soluble silicon-containing phenolic polymers through reaction of a carbocation of the crosslinking agent with the hydroxyl site of the phenolic group in the silicon-containing polymers. A chemically amplified silicon-containing negative-tone resist composition comprising said silicon-containing polymer resin; at least one crosslinking agent; one acid generator; and a solvent is provided. The silicon-containing resist composition has high silicon content and provide excellent resolution and a means of patterning high aspect ratio resist patterns.
