A method of manufacturing a semiconductor substrate structure for use in a semiconductor substrate stack system is presented. The method includes a semiconductor substrate which includes a front-face, a backside, a bulk layer, an interconnect layer that includes a plurality of inter-metal dielectric layers sandwiched between conductive layers, a contact layer that is between the bulk layer and the interconnect layer, and a TSV structure commencing between the bulk layer and the contact layer and terminating at the backside of the substrate. The TSV structure is electrically coupled to the interconnect layer and the TSV structure is electrically coupled to a bonding pad on the backside. |
