Semiconductor device having a via hole and its manufacturing method

摘要

A semiconductor device comprises at least one first electrode (11b) provided on the front surface of a semiconductor chip and electrically connected to at least one of electrodes that constitute a transistor, a second electrode (9) provided on the back surface of the semiconductor chip and electrically connected to one of the other electrodes, a via hole penetrating the semiconductor chip from the front surface to the back surface, and a through electrode (11a) a part of which is exposed on the front surface of the semiconductor chip electrically connected to the second electrode (9) through the via hole.
