Abstract:
1. A semiconductor element having an electrode on a surface thereof, the semiconductor element comprising: a wiring layer formed inside the semiconductor element; a conductive layer formed separate from the wiring layer so as to form a surface of the electrode; a plurality of pole-like members formed of a conductive material and extending between said wiring layer and the conductive layer and arranged adjacent to each other; an insulating layer formed of an insulating material filled between the plurality of pole-like members; and a frame member extending between said wiring layer and said conductive layer so as to surround said plurality of pole-like members and said insulating layer together, wherein an outer configuration of said conductive layer is equal to or larger than an outer configuration of said frame member, and said insulating layer is entirely and completely enclosed in a space defined by said conductive layer, said wiring layer and said frame member without any openings.
