Abstract:
1. A semiconductor device, comprising: a semiconductor substrate having a first surface and a second surface opposite to each other; a through hole provided in the semiconductor substrate; an insulation film provided along an inner surface of the through hole; a metal layer provided along an inner surface of the insulating film in the through hole, a metal layer tip of the metal layer protruding relative to the second surface of the semiconductor substrate; a through electrode provided along an inner surface of the metal layer in the through hole, a through electrode tip of the through electrode protruding relative to the second surface of the semiconductor substrate; a resin provided along an inner surface of the through electrode in the through hole, the resin being located inside the through electrode, a resin tip of the resin protruding relative to the second surface, wherein the through electrode tip is a bump electrode, the insulation film and the metal layer are provided between the inner surface of the through hole and the through electrode, and the metal layer tip terminates at a location between the through electrode tip of the through electrode and the second surface of the semiconductor substrate.
