Semiconductor device and method of manufacturing the same, circuit board, and electronic equipment

摘要

A method of manufacturing a semiconductor device includes: a first step of forming a first through hole that penetrates the location of the electrode in a semiconductor element having an electrode; a second step of providing an insulating material in a region including an inside of the first through hole 18, in such a manner that a second through hole is provided penetrating through the insulating material; and a third step of providing a conductive member within the second through hole that penetrates through at least the insulating material in the inside of the first through hole.
