Abstract
A solid-state semiconductor device operable without loss arising from junction-to junction (e.g., source-to-drain) leakage current includes a movable MEMS switch or relay armature structure carrying at least one electrical contact corresponding to a semiconductor device junction. The switch or relay armature is movable from a first position corresponding to a first switch state to a second position corresponding to a second switch state. The semiconductor device also includes an actuation circuit configured to act on the cantilever switch, changing the switch from a first contact-conducting state to a second non-contact-conducting state by physically separating the switch's electrical contact from the semiconductor device junction, thus eliminating the conductive path for leakage current losses.
