Classification: CPC H | IPC H

Claim 13:
14. An interposer comprising:
a silicon substrate having a first surface including a first plurality of electrical contacts configured to electrically couple directly to a first semiconductor device, and a second surface opposite the first surface and spaced from the first surface by a thickness of the substrate, the second surface including a second plurality of electrical contacts configured to electrically couple directly to a second semiconductor device;
a plurality of through-substrate vias disposed peripherally around the second plurality of electrical contacts, each through-substrate via including an exposed portion and an embedded portion, the exposed portions projecting from the second surface of the substrate by a distance greater than the thickness of the substrate, and the embedded portions extending through at least a portion of the substrate between the first surface and the second surface; and
at least one interconnect in the substrate connecting one of the first plurality of electrical contacts to one of the second plurality of electrical contact.
