Abstract: An example microelectromechanical structures (MEMS) switch includes a body having a first end and a second end opposite the first end. The body extends from a base at the first end and has a first width. The MEMS switch further includes a bridge extending laterally from the body at the second end, and a spine extending between the bridge and the base. The spine has a second width smaller than the first width. At least one of the spine or the body includes a first material with a first thermal coefficient and a second material with a second thermal coefficient different from the first thermal coefficient.

Abstract: A MEMs actuator device and method of forming includes arrays of actuator elements. Each actuator element has a moveable top plate and a bottom plate. The top plate includes a central membrane member and a cantilever spring for movement of the central membrane member. The bottom plate consists of two RF signal lines extending under the central membrane member. A MEMs electrostatic actuator device includes a CMOS wafer, a MEMs wafer, and a ball bond assembly. Interconnections are made from a ball bond to an associated through-silicon-via (TSV) that extends through the MEMS wafer. A RF signal path includes a ball bond electrically connected through a TSV and to a horizontal feed bar and from the first horizontal feed bar vertically into each column of the array. A metal bond ring extends between the CMOS wafer and the MEMS wafer. An RF grounding loop is completed from a ground shield overlying the array to the metal bond ring, a TSV and to a ball bond.
