Non-ionic photo-acid generating (PAG) polymerizable monomers were prepared that contain a side chain sulfonate ester of an alpha-hydroxy aryl ketone. The aryl ketone group has a perfluorinated substituent alpha to the ketone carbonyl. The sulfur of the sulfonate ester is also directly linked to a fluorinated group. PAG polymers prepared from the PAG monomers release a strong sulfonic acid when exposed to high energy radiation such as deep UV or extreme UV light. The photo-generated sulfonic acid has a low diffusion rate in an exposed resist layer subjected to a post-exposure bake (PEB) at 100° C. to 150° C., resulting in formation of good line patterns after development.
New photoresists are provided that are useful in a variety of applications, including negative-tone development processes. Preferred resists comprise a first polymer comprising first units comprising a reactive nitrogen-containing moiety spaced from the polymer backbone, wherein the nitrogen-containing moiety produces a basic cleavage product during lithographic processing of the photoresist composition.

The present invention provides an adamantane derivative (I) having a structure represented by the general formula (I); an adamantane derivative (II) having a structure represented by the general formula (II); and a process for producing those adamantane derivatives. An alcohol form of an adamantane compound is reacted with a sulfonyl compound to obtain the adamantane derivative (II), which is then reacted with an alcohol to obtain the adamantane derivative (I). The adamantane derivative (I) and adamantane derivative (II) each having the structure represented by the general formula (I) and general formula (II), respectively, is a novel adamantyl(meth)acrylate compound and useful as a monomer for functional resins such as a photosensitive resin in the field of photolithography.
