Semiconductor device with a reduced width gate dielectric and method of making same

摘要

The present invention is directed to a semiconductor device having a reduced feature size and a method of making same. The device is comprised of a gate dielectric positioned above a semiconducting substrate, and a gate conductor positioned above said gate dielectric. The width of the gate dielectric being less than the width of the gate conductor. The device further comprises a plurality of sidewall spacers adjacent said conductor. The method is comprised of forming a gate dielectric above the surface of a semiconducting substrate, forming a gate conductor above the gate dielectric, and wet etching the gate dielectric to a finished width that is less than the width of the gate conductor.
