    Abstract: New photoresist compositions are provided that are useful for immersion lithography. Preferred photoresist compositions of the invention comprises two or more distinct materials that can be substantially non-mixable with a resin component of the resist. Particularly preferred photoresists of the invention can exhibit reduced leaching of resist materials into an immersion fluid contacting the resist layer during immersion lithography processing.
