ABSTRACT:
The invention provides inter alia new methods to produce aqueous developable resin binders for negative-acting photoresists. The methods in general comprise free radical polymerization of one or more types of monomers in the presence of a free radical polymerization control agent, particularly a nitroxide polymerization control agent such as a piperidinyloxy (N-oxy) free radical, and wherein at least one of the monomer types contains a moiety that enables aqueous solution development of a photoresist composition containing the formed polymer.
