A chemically amplified positive resist composition is a pattern-forming material in which an acid generates in exposed areas upon irradiation with a radiation such as far ultraviolet rays and this acid catalyzes a reaction that makes the areas irradiated with the actinic rays and the unirradiated areas to differ in solubility in a developing solution to thereby form a pattern on a substrate. If the UV-exposed regions remain (vanish) after development, the resist is said to be negative (positive). Especially preferred alkali-soluble resins for use in the present invention are novolak resins, alkali-soluble resins comprising p-hydroxystyrene units (more preferably poly(p-hydroxystyrene), p-hydroxystyrene/m-hydroxystyrene copolymers, p-hydroxystyrene/o-hydroxystyrene copolymers, and p-hydroxystyrene/styrene copolymers), alkyl-substituted hydroxy resins such as 4-hydroxy-3-methylstyrene resins and 4-hydroxy-3,5-dimethylstyrene resins, resins obtained from the above resins by converting OH groups thereof into alkyl or acetyl groups, partially hydrogenated poly(hydroxystyrene) resins, poly(hydroxystyrene) resins, partially hydrogenated novolak resins, and partially hydrogenated poly(hydroxystyrene) resins. ��cM�LtHwY�Z�ݏ�r�N�C��!�p���d��G|0sy���㚈b��ajF�W�z�X��qt��"$��Af�x�M=��z�&�s@�-lOPc9��h�@TbΣ����@��:="A�����2�} (�4�9z4,8�����揉h3cY�֑ΖE���3��G����Od!C��&���v؛�g,��oN� ��|�O#n���:�-�/�{��O��|D`UyB1�_GE}�����Y�*� z��)��y�ɴ)d�N�z[7�x���W:;�� Nos.
