Abstract:
1. A multilayer structure forming method using a droplet discharge apparatus, comprising: (A) discharging droplets of a first conductive material to a position corresponding to a wiring pattern to form a first conductive material pattern on a surface of an object; (B) baking the first conductive material pattern to form the wiring pattern; (C) discharging droplets of a first insulating material to a position corresponding to an underlying region surrounding a post formation region, the post formation region being positions set on the wiring pattern and surrounded by the first insulating material, the first insulating material including a first photo-curable material to form a first insulating material pattern bordering via holes on the wiring pattern; (D) curing the first insulating material pattern to form a first insulating pattern bordering the via holes; (E) making the surface of the object lyophilic; (F) discharging droplets of a second insulating material to a position corresponding to a second insulating pattern, the second insulating material including a second photo-curable material to form a second insulating material pattern that covers the wiring pattern and the surface of the object which has been made lyophilic, and surrounds the first insulating pattern; and (G) curing the second insulating material pattern to form a second insulating pattern that surrounds the first insulating pattern, the surface of the first insulating pattern and the surface of the second insulating pattern constituting a same level.
