Method and apparatus for forming a semiconductor gate

摘要

The present disclosure provides an apparatus and method for fabricating a semiconductor gate. The apparatus includes, a substrate having an active region and a dielectric region that forms an interface with the active region; a gate electrode located above a portion of the active region and a portion of the dielectric region; and a dielectric material disposed within the gate electrode, the dielectric material being disposed near the interface between the active region and the dielectric region. The method includes, providing a substrate having an active region and a dielectric region that forms an interface with the active region; forming a gate electrode over the substrate, the gate electrode having an opening near a region of the gate electrode that is above the interface; and filling the opening with a dielectric material.
