Abstract: Systems and methods for a MEMS device, in particular, a MEMS switch, and the manufacture thereof are provided. In one example, said MEMS device comprises posts and a conduction (transmission) line formed over a substrate and a membrane over the posts and the conduction line. The membrane comprises a first membrane layer and a second membrane layer formed over the first membrane layer in a region over one of the posts and/or a region over the conduction line such that the first membrane layer has a region where the second membrane layer is not formed adjacent to the region where the second membrane layer is formed.

Abstract: The MEMS structure comprises: a flexible membrane (6), which has a main longitudinal axis (6a) defining a longitudinal direction (X), at least one pillar (3, 3?) under the flexible membrane (6), electric lowering actuation means (7) that are adapted to bend down the flexible membrane (6) into a down forced state electric raising actuation means (8) that are adapted to bend up the flexible membrane (6) into an up forced state. The electric lowering actuation means (7) or the electric raising actuation means (8) comprise an actuation area (7c or 8c), that extends under a part of the membrane (6) and that is adapted to exert pulling forces on the membrane (6) simultaneously on both sides of the said at least one pillar (3) in the longitudinal direction (X).
