Abstract
An electrostatically actuated capacitive MEMS switch includes a plurality of cantilever springs which are actuated parallel to the plane of a substrate. The springs are connected to posts vertically formed on the substrate, and an insulating layer for preventing direct contact between springs and inducing switching depending on a variation in capacitance between the springs is formed on the surface of each of the springs. An opening is formed in the substrate, and the springs are located over the opening. Each of the springs has both lateral portions located on different planes and a slanted middle portion for connecting the two lateral portions to each other.
