Abstract

A transistor may be provided by forming, in a forward order or in a reverse order, a gate electrode, a semiconducting metal oxide liner, a gate dielectric, and an active layer over a substrate, and by forming a source electrode and a drain electrode on end portions of the active layer. The semiconducting metal oxide liner comprises a thin semiconducting metal oxide material that functions as a hydrogen barrier material.
