Abstract

An electro-statically actuated switch having a reduced gap distance between electrodes for reducing actuation voltage is provided. The invention provides more reliable electro-statically actuated switches. The invention provides a micro-electro-mechanical system (MEMS) that includes a recessed, movable electrode. The invention provides electro-statically actuated switches that reduce the likelihood of stiction and beam deformation and that allows lower actuation voltage for electrostatically actuated structures such as switches and mirrors. A method for fabricating such a design is provided that allows lower actuation voltage.
