Abstract:
1. A hermetically-packaged integrated circuit, an integrated circuit device positioned proximate an outer surface of a first substrate layer; a conductive region operable to transfer electrical signals to or from the integrated circuit device, the conductive region comprising a portion of material of the first substrate layer that has been changed to exhibit conductive properties; a metal contact formed proximate the outer surface of the first substrate layer; a via formed through a portion of the first substrate layer to expose an underside surface of the conductive region; at least one conductive layer at least partially filling the via; and a second substrate layer disposed proximate the outer surface of the first substrate layer to enclose the integrated circuit device in a hermetic environment; wherein the conductive region comprises a silicide material diffused into the first substrate layer, the silicide layer formed by a reaction between a metal layer formed on the outer surface of the first substrate layer and the material of the first substrate layer.
