Abstract: PROBLEM TO BE SOLVED: To obtain a photoresist composition using an acid as a catalyst, capable of forming an image with radiation of 193 nm and capable of forming a photoresist structure having high resolution and high etching resistance by development. SOLUTION: The photoresist composition comprises a combination of a cyclic olefin polymer, a photosensitive acid-generating agent and a substantially transparent bulky hydrophobic additive. The cyclic olefin polymer contains a cyclic olefin unit having a polar functional group which promotes dissolution in an aqueous alkali solution and the cyclic olefin unit having an acid-labile group which inhibits the dissolution in the aqueous alkali solution. The hydrophobic additive is selected from the group comprising a saturated steroid compound, a non-steroid cycloaliphatic compound and a non-steroid polycycloaliphatic compound having an acid-labile bond.

Abstract: ACID-CATALYZED POSITIVE PHOTORESIST COMPOSITIONS WHICH ARE IMAGEABLE WITH 193 NM RADIATION AND ARE DEVELOPABLE TO FORM PHOTORESIST STRUCTURES OF HIGH RESOLUTION AND HIGH ETCH RESISTANCE ARE ENABLED BY THE USE OF A COMBINATION OF CYCLIC OLEFIN POLYMER, PHOTOSENSITIVE ACID GENERATOR AND BULKY HYDROPHOBIC ADDITIVE WHICH IS SUBSTANTIALLY TRANSPARENT TO 193 NM RADIATION. THE CYCLIC OLEFIN POLYMERS CONTAIN I) CYCLIC OLEFIN UNITS HAVING ACIDIC POLAR FUNCTIONAL MOIETIES THAT PROMOTE SOLUBILITY IN AQUEOUS ALKALINE SOLUTIONS, AND II) CYCLIC OLEFIN UNITS HAVING ACID LABILE MOIETIES THAT INHIBIT SOLUBILITY IN AQUEOUS SOLUTIONS.
