1. A method of fabricating a semiconductor device comprising:

  • a first step of forming a through hole in a semiconductor element having a plurality of electrodes on a first surface; and

    a second step of forming a conductive layer which is electrically connected to the electrodes and is provided from the first surface through an inner wall of the through hole to a second surface of the semiconductor element which is opposite to the first surface, wherein the conductive layer is formed to have connecting portions on the first and second surfaces so that a distance between at least two electrodes among the plurality of electrodes is different from a distance between the connecting portions on at least one of the first and second surfaces, in the second step.
