Abstract:
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 an annular cavity (18) and 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 three-dimensional integration is offered by this scheme.
