Semiconductor device and semiconductor module employing thereof
Abstract:
A semiconductor device is provided with a silicon substrate and a structure filled in a through hole that has a rectangular cross section and extends through the silicon substrate. The structure comprises a pipe-shaped through electrode, stripe-shaped through electrodes, silicons, a first insulating film, a second insulating film and a third insulating film. The pipe-shaped through electrode is utilized as a pipe-shaped electric conductor that extends through the silicon substrate. In addition, the stripe-shaped through electrodes are provided in the interior of the pipe-shaped through electrode so that the stripe-shaped through electrodes extend through the silicon substrate and is spaced away from the pipe-shaped through electrode. A plurality of through electrodes are provided in substantially parallel within the inner region of the pipe-shaped through electrode.
