Abstract

A method of fabricating a transistor structure is provided. The method comprises forming a gate electrode in a dielectric layer of an interconnect structure; forming a monolayer on a portion of the dielectric layer laterally spaced from the gate electrode; sequentially forming a ferroelectric layer, a barrier layer and a channel layer on the gate electrode; and forming a source/drain electrode on the channel layer.
