The semiconductor device comprises a semiconductor substrate (10) with a metallization (111) having an upper terminal layer (22) located at a front side (20) of the substrate. The metallization forms a through-substrate via (23) from the upper terminal layer to a rear terminal layer (13) located opposite to the front side at a rear side (21) of the substrate. The through-substrate via comprises a void (101), which may be filled with air or another gas. A solder ball (100) closes the void without completely filling it. A variety of interconnections for threedimensional integration is offered by this scheme.
摘要:
Various aspects of an approach for routing die signals in an interior portion of a die using external interconnects are described herein. The approach provides for contacts coupled to circuits in the interior portion of the die, where the contacts are exposed to an exterior portion of the die. The external interconnects are configured to couple these contacts so that signals from the circuits in the interior portion of the die may be routed externally to the die. In various aspects of the disclosed approach, the external interconnects are protected by a packaging for the die.
