摘要： A piezoelectric micro electro-mechanical system switch (MEMS), an array of piezoelectric MEMS switches, and a method of fabricating the switch, which are capable of improving low voltage and switching characteristics while securing high signal isolation, are provided. The piezoelectric MEMS switch includes a semiconductor substrate including a groove, a support formed over the semiconductor substrate and the groove. An actuator including a piezoelectric layer is formed on the support. A switching member is formed on the support on one side of the actuator, wherein upward movement of the switching member changes by a deformation of the piezoelectric layer of the actuator. Radio frequency (RF) transfer lines are arranged at a predetermined distance on the switching member and are separated by a predetermined interval from each other. The actuator is formed to have at least two cantilevers each having one end such that the ends are connected to each other.

摘要： The present invention relates to a capacitive micro-electro-mechanical switch and method of manufacturing the same. In the capacitive micro-electro-mechanical switch for use in the radio frequency (RF) and the microwave driven by the electrostatic force, a capacitor of a 3-dimensional structure is formed on a signal transmission line. An ON capacitance is increased without increasing an capacitor area while preventing an increase in an OFF capacitance using the capacitor. Thus, an ON/OFF capacitance ratio of the capacitive micro-electro-mechanical switch can be increased and insertion loss and isolation characteristic could be improved.
