Abstract

Lateral FET structure is disclosed for bidirectional power switching. A split gate structure is provided to prevent unwanted formation of potential conduction channels in the OFF state of the FET. This enables the gate to be referenced in common to one of the source regions in the OFF state while still affording high blocking voltage capability. A multicell matrix array is also disclosed.
