Abstract: PROBLEM TO BE SOLVED: To provide a circuit substrate by a method wherein a high-precision circuit pattern is formed at least on one surface of a liquid crystal polymer film subject to dimensional changes due to external force. SOLUTION: In this method, a reinforcement board and one of the surfaces of the liquid crystal polymer film is bonded together by an organic layer in between, a circuit pattern is formed on the other surface of the polymer film, and then the polymer film is released from the reinforcement board.

Abstract: PROBLEM TO BE SOLVED: To form a circuit pattern of high accuracy even on a flexible film which is liable to cause a change in dimension by the influence of heat, humidity or external force. SOLUTION: In this production method for circuit board, the flexible film is stuck with a reinforcing plate through a releasable organic layer. After the circuit pattern is formed on the flexible film, the flexible film is released from the reinforcing plate.

Abstract: PURPOSE: To prevent the omission due to cracking even when a pattern is formed on a curved or twisted structure and to make a photosensitive compsn. applicable to a rugged or curved surface as well as a plane surface by using a specified photosensitive compd. having a quinone-diazido group as a photosensitive component. CONSTITUTION: This photosensitive compd. has a structure represented by formula I, II or III. In the formulae I-III, each of R1-R4 is a 1 to 100C optionally substd. hydrocarbon group which may contain an ester bond, an ether bond, a thio-ether bond, an amido bond, a urethane bond, a urea bond, Si and N, M is a quinonecliazido group, >=20% of carbon atoms forming the skeleton of each of R1 and R2 do not belong to an arom. ring and >=20% of carbon atoms forming the skeleton of at least one of R3 and R4 do not belong to an arom. ring. This photosensitive compd. is softer and more excellent. in pattern forming property than a photosensitive compd. using phenol-novolak resin.
