摘要
A vertical ferroelectric gate field-effect transistor (FeGFET) device comprises a substrate and a first drain/source electrode formed on an upper surface of the substrate. An electrically conductive channel region is formed on an upper surface of the first drain/source electrode and electrically contacting the first drain/source electrode. The FeGFET device further comprises a ferroelectric gate region formed on at least one side wall of the channel region, at least one gate electrode electrically contacting the ferroelectric gate region, and a second drain/source electrode formed on an upper surface of the channel region and electrically contacting the channel region. The ferroelectric gate region is selectively polarizable in response to a potential applied between the gate electrode and at least one of the first and second drain/source electrodes. A non-volatile memory array can be formed comprising a plurality of FeGFET devices.
