Abstract: PROBLEM TO BE SOLVED: To remove the projecting part of resin filling a through hole without relying upon abrasion by providing a step for filling a through hole with resin such that the resin projects from the surface of a board, a step for dissolving the projecting part of resin, and a step for curing resin. SOLUTION: A through hole made in a board 2 is filled with a resin 1 being dissolved by a developer, e.g. photoresist. The board 2 is passed through a unfoaming process and then immersed into a developer 4 in order to dissolve a part of resin 1 projecting from the surface of the board. The developer 4 employs an organic agent, e.g. xylene, for negative resist and alkaline aqueous solution for positive resist. After the projecting part is removed, the resin is cured by heat treatment or by irradiation with UV-rays in case of negative resist. Contrary to conventional abrasion, the board does not elongate and the projecting part of resin can be removed through a simple process.

Abstract: PROBLEM TO BE SOLVED: To simultaneously form narrow and wide trenches of the same depth by canceling out an etching rate difference caused by etching microload effect by the difference in thickness between a coating layer on the bottom of a narrow contact hole pattern and a coating layer on the bottom of a wide trench pattern. SOLUTION: A coating layer 27 on the bottom of a narrow contact hole pattern 25 is thinner than a coating layer 27 on the bottom of a wide trench pattern 26.
