Patent ID: 8729657

Claim:
A microelectromechanical system (MEMS) device, comprising: a substrate; an electrically conductive gate terminal on the substrate; an electrically conductive first source landing pad on the substrate proximate to the gate terminal; an electrically conductive first drain landing pad on the substrate proximate to the gate terminal, on a same side of the gate terminal as the first source landing pad; an electrically conductive second source landing pad on the substrate proximate to the gate terminal, on an opposite side of the gate terminal from the first source landing pad; an electrically conductive second drain landing pad on the substrate proximate to the gate terminal, on a same side of the gate terminal as the second source landing pad; an electrically conductive first body bias element on the substrate adjacent to the gate terminal, on the same side of the gate terminal as the first source landing pad; an electrically conductive second body bias element on the substrate adjacent to the gate terminal, on the same side of the gate terminal as the second source landing pad; electrically conductive hinge posts connected to the gate terminal; a torsion hinge connected to the hinge posts; an electrically conductive gate attached to the torsion hinge; a channel isolation layer on the gate; an electrically conductive first channel on the channel isolation layer, the first channel including a first source contact over the first source landing pad and a first drain contact over the first drain landing pad, the first channel being electrically isolated from the gate; and an electrically conductive second channel on the channel isolation layer, the second channel including a second source contact over the second source landing pad and a second drain contact over the second drain landing pad, the second channel being electrically isolated from the gate; wherein: the gate is configured to pivot on the torsion hinge so that the first source contact touches and makes electrical contact with the first source landing pad and the first drain contact touches and makes electrical contact with the first drain landing pad when a threshold bias potential difference is applied between the gate terminal and the first body bias element; and the gate is configured to pivot on the torsion hinge so that the second source contact touches and makes electrical contact with the second source landing pad and the second drain contact touches and makes electrical contact with the second drain landing pad when a threshold bias potential difference is applied between the gate terminal and the second body bias element.
