In this paper, we present an alternative method of rivet packaging for radio frequency microelectromechanical system (RF MEMS) devices and evaluate its electrical characteristics. The rivet packaging enables not only encapsulation but also through-via interconnection at the same time. Moreover, it is possible to achieve a wafer-level process. The electrical performance was evaluated using Cu hollow-filled through-via interconnection. The overall insertion loss of the through-via interconnection from the bottom CPW to the top CPW decreased from 0.04 to 0.11 dB at 2 GHz and from 0.06 to 0.23 dB at 5 GHz.
