Abstract
A semiconductor device (and method for forming the device) includes a silicon-on-insulator (SOI) wafer formed on a substrate surface. An isolation trench in the wafer surface surrounds alternating p-type trenches and n-type trenches and electrically isolates the device from the substrate, thereby allowing the device to be effectively utilized as a differential detector in an optoelectronic circuit.
