Abstract:
A MEMS switch includes a substrate and a switch structure formed on the substrate, with the switch structure further including a conductive contact formed on the substrate, a self-compensating anchor structure coupled to the substrate, and a beam comprising a first end and a second end, the beam integrated with the self-compensating anchor structure at the first end and extending out orthogonally from the self-compensating anchor structure and suspended over the substrate such that the second end comprises a cantilevered portion positioned above the conductive contact. The cantilevered portion of the beam undergoes deformation during periods of strain mismatch between the substrate and the switch structure so as to have a takeoff angle relative to the substrate, and the self-compensating anchor structure directs a portion of the strain mismatch orthogonally to the cantilevered portion so as to warp the anchor and compensate for the takeoff angle of the cantilevered portion.
