Ferroelectric field effect transistor with nanowire core

Abstract:

A ferroelectric field effect transistor (FeFET) is provided. The FeFET includes a buried oxide (BOX) layer; a nanowire layer including pads formed on the BOX layer at source and drain regions of the FeFET, and a nanowire core extending between the pads and over a recess formed in the BOX layer; a metal electrode coating the nanowire core; a ferroelectric layer coating the metal electrode; an interfacial layer coating the ferroelectric layer; and a polysilicon layer formed over a channel region of the FeFET, the polysilicon layer coating the interfacial layer.
