Method to manufacture silicon quantum islands and single-electron devices

摘要

A method of manufacturing a single-electron transistor device is provided. The method includes forming a thinned region in a silicon substrate, the thinned region offset by a non-selected region. The method also includes forming at least one quantum island from the thinned region by subjecting the thinned region to an annealing process. The non-selected region is aligned with the quantum island and tunnel junctions are formed between the quantum island and the non-selected region. The present invention also includes a single-electron device, and a method of manufacturing an integrated circuit that includes a single-electron device.
