Patent ID: 7370412

Claim:
An electronic device connecting method comprising: mounting an electrode of an electronic device closely on a sheet-like porous member having pores, the porous member having a photosensitive layer formed on an inner surface of pores, the photosensitive layer producing or eliminating an ion exchange group by irradiation with energy beams on the inner surface of the pores; selectively irradiating a predetermined region of the porous member, on which the electronic device is mounted, with energy beams thereby exposing the photosensitive layer to form a latent image in an irradiated or non-irradiated portion of the porous member, the predetermined region including a portion close to the electrode; after said selectively irradiating, filling pores in the latent image of the porous member with a conductive material to simultaneously form a wiring portion and a via contact connected to the electrode; and bonding the porous member, in which the wiring portion and the via contact are formed by said filling, to the electronic device.
