Abstract: New photoresist compositions are provided that comprise a carbamate compound that comprises 1) a carbamate group and 2) an ester group. Preferred photoresists of the invention may comprise a resin with acid-labile groups; an acid generator compound; and a carbamate compound that can function to decrease undesired photogenerated-acid diffusion out of unexposed regions of a photoresist coating layer.
