  • Chemically amplified, radiation-sensitive resin composition
    Patent number: 5731125
    Abstract: A chemically amplified, radiation-sensitive resin composition which comprises a radiation-sensitive acid-generator which generates an acid upon irradiation with a radiation and in which the chemical change due to the catalytic action of said acid changes the solubility of the irradiated portion in a developer to form a pattern, characterized by comprising an anthracene derivative of the formula (1), representatives of which are anthracene-9-methanol and anthracene-9-carboxyethyl.
