Patent ID: 8264082

Claim:
An electronic element having a front-side and a final backside and having one or more electronic devices proximate the front-side from which current flows to the final backside of the element, comprising: a substrate having an upper surface and having an initial lower surface and having a final lower surface forming the final backside, the final lower surface being displaced from the initial lower surface, and one or more conductor filled pipes or trenches electrically coupled to the one or more electronic devices and extending between the upper surface and the final backside for substantially conducting the current flowing from the one or more electronic devices to the final backside of the element; an epitaxial layer on the upper surface and over the one or more conductor filled trenches extending from the upper surface to the front side of the element, such epitaxial layer being adapted to substantially contain the one or more electronic devices; and wherein the one or more conductor filled pipes or trenches, the epitaxial layer and the one or more electronic devices are substantially formed prior to removing material from the initial lower surface to form the final backside.
