SILICON BASED OPTO-ELECTRIC CIRCUITS

摘要

A semiconductor structure, comprising: a substrate; a seed layer over an upper surface of the substrate; a semiconductor layer disposed over the seed layer; a transistor device in the semiconductor layer; wherein the substrate has an aperture therein, such aperture extending from a bottom surface of the substrate and terminating on a bottom surface of the seed layer; and an opto-electric structure disposed on the bottom surface of the seed layer.
