Patent ID: 7439010

Claim:
A process for manufacturing an electronic device, comprising the steps of: forming a resist pattern on an underlying layer by a process for forming a resist pattern; and patterning the underlying layer by one of etching and lift-off, utilizing the resist pattern as a mask, wherein the process for forming a resist pattern comprises the steps of: forming a resist film utilizing a positive type resist composition; and forming a resist pattern by developing, wherein the positive type resist composition comprises: an alkali-soluble siloxane polymer expressed by the following Formula (1); and a photoreactive compound; wherein a 1 μm thick resist film formed of the positive type resist composition has 5% to 60% of transmittance to i-line radiation; in the Formula (1), R 1 and R 2 express a monovalent organic group, and may be identical or different; “A” is a group expressed by the following Formula (2) having at least one phenolic hydroxyl group; and “a”, “b,” and “c” satisfy the following relation; a+b+c=1, and 0.02≦c≦0.20, wherein in Formula (2), R 3 , R 4 and R 5 express one of a hydrogen atom and a monovalent organic group, and may be identical or different; m expresses an integer; and n expresses an integer of 1 to 5,
