The present subject matter relates to systems, devices, and methods for reducing surface dielectric charging in a RF MEMS actuator element. In particular, a micro-electro-mechanical systems (MEMS) can comprise a fixed electrode positioned on a substrate, a moveable electrode positioned substantially above the fixed electrode and separated from the fixed electrode by a gap, and at least one standoff bump positioned between the fixed electrode and the moveable electrode, wherein the at least one standoff bump extends into the gap. In this configuration, one or both of the fixed electrode or the moveable electrode can be patterned to define one or more hole that is substantially aligned with the one or more of the at least one standoff bump. The bump and the hole can both help to reduce the rate of surface dielectric charging and the total amount of charge generated. |
