IPC: H05K3/46
Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a multilayer printed wiring board which allows effective formation of a blind via hole of a high connection reliability without leaving residues of an insulating layer. SOLUTION: On the surface of a conductor circuit having an inner layer circuit 2, a photosensitive resin film 3 which swells with an alkaline solution is formed. After that, the photosensitive resin film 3 is left over only in a blind via hole 10 formation section by exposure and development. Nextly, an insulating layer 4 which does not swell with an alkaline solution is formed over the entire surface and is flattened. Then, the remaining photosensitive resin film 3 is swollen with an alkaline solution and stripped to make a hole, which becomes a blind via hole 10.

Thereby, the draft for burning is decreased, accordingly, the amount of burning  is varied. Therefore, the burning draft can be widely changed without deteriorating the conditions of burning, and also the amount of burning can be changed widely.
