Claim Text:
1. A method of forming a sensor device, the method comprising the steps of: providing a substrate having a first surface and a second surface opposite the first surface; etching a portion of the substrate to form an etch region; after the step of etching, forming a first implantation-barrier mask on the first surface and forming a second implantation-barrier mask on the second surface; performing a separation by implantation of oxygen (SIMOX) process on the first surface and the second surface; after the SIMOX process, exposing the substrate to an anneal process to form a buried insulating region separating a semiconductor layer and a buried semiconductor material, wherein a first portion of the semiconductor layer forms a channel of the sensor device; forming a source region using a second portion of the semiconductor layer overlying a first surface of the substrate; and forming a drain region using a third portion of the semiconductor layer overlying a second surface of a substrate, wherein a nanopore is formed within the etch region.
