Abstract: The present invention is directed to a method of performing alignment during processing of a semiconductor device. The method is comprised of: performing alignment registration on a plurality of layers on said semiconductor device; measuring misregistration of said alignment registration in relation to a predetermined standard alignment key; and generating an offset for a subsequent process layer on said semiconductor using said measure misregistration.

Abstract: A contact formed from the backside of an integrated circuit device includes a first conductive layer on a first surface of the integrated circuit device and a second conductive layer on a second surface of the device. The two conductive layers are coupled by way of an opening through the semiconductor substrate separating the two conductive layers. A method for making the backside contact comprises forming the first conductive layer, forming an opening through the semiconductor substrate to expose at least a portion of the underside of the first conductive layer, then filling the opening with a conductive material to provide an electrical contact to the first conductive layer from the backside of the integrated circuit device.
