Title: Radiation sensitive composition and pattern forming method using the same
Inventor: KOJIMA KYOKO
IPC: G03F7/038
Filed: 1994-10-07
Abstract: PURPOSE: To obtain excellent thermal stability, high sensitivity and high resolution by incorporating an alkali-soluble high polymer, secondary alcohol having a hydroxyl group on carbon directly bonded to an arom. ring and an acid precursor which generates an acid by irradiation with radiation. CONSTITUTION: This compsn. contains an alkali-soluble resin, the secondary alcohol having the hydroxyl group on the carbon directly bonded to the arom. ring and the acid precursor which generates the acid by irradiation with radiation. The secondary alcohol having the hydroxyl group on the carbon directly bonded to the arom. ring is a phenyl methanol deriv. The secondary alcohol which has the hydroxyl group on the carbon directly bonded to the arom. ring and is included in this radiation sensitive compsn. induces dehydration reaction with high efficiency and forms a water repellent compd. when heated in the presence of a strong acid.  The dehydration reaction is, therefore, induced by the acid generated from the acid precursor in the region irradiated with the radiation when the compsn. is heated after the irradiation with the radiation and, therefore, the compsn. is made insoluble in an alkaline developer.
