Patent ID: 7373717

Claim:
A method of manufacturing a self-sustaining center-anchor microelectromechanical switch, the method comprising the steps of: after forming a thin film on a substrate with an insulating material, patterning the thin film using a predetermined mask; forming transmission lines and ground lines in a patterned portion; depositing and patterning a sacrificial layer on the transmission lines and the ground lines to form a self-sustaining center-anchor; forming a switching unit made of a metal that electrically connects the transmission lines on the sacrificial layer during short-circuit operation; forming a dielectric-moving plate that allows the transmission lines and the ground lines to be spaced apart with a constant gap by a plurality of electrode and edge-anchors to the switching unit and an upper electrode; forming the upper electrodes that act as a driving electrode to the ground line on the dielectric-moving plate; and removing the sacrificial layer formed between the dielectric-moving plate and the transmission line.
