Patent ID: 7972651

Claim:
A method for forming a multi-layered structure using a droplet-discharging device, comprising: forming a first insulating-material layer, which covers a material-body surface, by discharging a droplet of a first insulating material including a first photosensitive resin to the material-body surface; obtaining a first insulating layer by curing in the first insulating-material layer, the curing the first insulating-material including irradiating the first insulating-material layer with ultraviolet light with a first wavelength; making the surface of the first insulating layer lyophilic, the making the surface of the first insulating layer lyophilic including irradiating the surface of the first insulating layer with ultraviolet light with a second wavelength different from the first wavelength; forming a pattern of an electric conductive material layer on the first insulating layer by discharging a droplet of an electric conductive material to the first insulating layer; and forming a wiring pattern on the first insulating layer by activating the pattern of the electric conductive material layer; forming a second insulating-material layer, which covers the first insulating layer and the electric conductive material layer, by discharging a droplet of a second insulating material including a second photosensitive resin to the first insulating layer and the electric conductive material layer, a contact angle formed between the first insulating layer and the second insulating material being 20 degrees or less; and curing the second insulating-material layer.
