Abstract:
1. A semiconductor package comprising: a semiconductor substrate which has a first surface, a second surface, and a through-hole extending from the second surface through to the first surface; a semiconductor element provided with a circuit element on the first surface of said semiconductor substrate; an external wiring region provided on the second surface of said semiconductor substrate; a connection section which is provided on said external wiring region for providing a connection to an external terminal; a support substrate disposed on the first surface of said semiconductor substrate; an electrode pad provided at an end of said through-hole on the first surface of said semiconductor substrate; an electrical insulation film which is provided on the inside surface of said through-hole and which extends from the lower surface of said electrode pad to the second surface of said semiconductor substrate; a through-electrode made of a metallic thin film which is formed on said electrical insulation film along the inside surface of said through-hole and which extends from said electrode pad through to the second surface of said semiconductor substrate; an external wire which extends from said through-electrode and connects to said external wiring region; and a protective film which covers the entire portions of said through-electrode inside said through-hole and the entire second surface side of said semiconductor substrate excluding said connection section.
