    Abstract: The process begins with separate device wafers having complimentary chips. Thin metal capture pads, having a preferred thickness of about 10 microns so that substantial pressure may be applied during processing without damaging capture pads, are deposited on both device wafers, which are then tested and mapped for good chip sites. A handle wafer is attached to one device wafer, which can then be thinned to improve via etching and filling. Capture pads are removed and replaced after thinning. The device wafer with handle wafer is diced, and good chips with attached portions of the diced handle wafer are positioned and bonded to the good chip sites of the other device wafer, and the handle wafer portions are removed. The device wafer having known good 3-D chips then undergoes final processing.

    Abstract: A structure and process are described for facilitating the conduction of heat away from a semiconductor device. Thermally conductive planes and columns are incorporated within the back-end structure and around the interconnect outside the chip. A thermally conductive plane is formed by forming a first insulating layer on an underlying layer of the device; forming a recess in the insulating layer; filling the recess with a thermally conductive material to form a lateral heat-dissipating layer; planarizing the heat-dissipating layer to make the top surface thereof coplanar with the unrecessed portion of the insulating layer; and forming a second insulating layer on the first insulating layer and the heat-dissipating layer, thereby embedding the heat-dissipating layer between the first and second insulating layers. The heat-dissipating layer is electrically isolated from the underlying layer of the device, and preferably is electrically grounded.
