Abstract:
1. A silicon based substrate, comprising: a silicon wafer comprising a first surface and a second surface opposite to the first surface, and at least a through silicon via penetrating the first surface and the second surface; a first circuit substrate disposed on the first surface of the silicon wafer, the first circuit substrate comprising a plurality of first dielectric layers and a plurality of first conductive trace layers alternately stacked; and a second circuit substrate disposed on the second surface of the silicon wafer, the second circuit substrate comprising a plurality of second dielectric layers and a plurality of second conductive trace layers alternately stacked; wherein the at least a through silicon via is respectively electrically connected to the bottommost first conductive trace layer of the first circuit substrate and the uppermost second conductive trace layer of the second circuit substrate, the first dielectric layers comprise an inorganic material, and the second dielectric layers comprise an organic material.
