Abstract
A method of integrating a topside optical device, having electrical contacts on a top side, with an electronic chip having electrical contacts on a connection side, involves creating a trench, defined by a wall, from the top side of a wafer containing the topside optical device into a substrate of the wafer, making a portion of the wall conductive by applying a conductive material to the portion; and thinning the substrate to expose the conductive material.
