ABSTRACT:
A latching zip-mode actuated mono wafer MEMS switch especially suited to capacitance coupled signal switching of microwave radio frequency signals is disclosed. The single wafer fabrication process used for the switch employs sacrificial layers and liquid removal of these layers in order to also provide needed permanent physical protection for an ultra fragile switch moving arm member. Latched operation of the achieved MEMS switch without use of conventional holding electrodes or magnetic fields is also achieved. Fabrication of a single MEMS switch is disclosed however large or small arrays may be achieved.
