First Claim
1. A method for manufacturing a micro-electro-mechanical switch assembly comprising:
- depositing an electrode material on a surface of a substrate;
depositing a dielectric material to form a dielectric layer on at least a portion of a surface of the electrode material;
depositing a metal layer on at least a portion of a surface of the dielectric layer, the metal layer having a plurality of openings extending through the metal layer;
depositing a plurality of posts on the substrate at positions spaced apart from the electrode material;
depositing a spacer material on the metal layer and between the posts;
depositing a flexible membrane on the spacer material and the posts; and
etching the spacer material from the assembly.

Abstract
Systems and methods for providing high-capacitive RF MEMS switches are provided. In one embodiment, the invention relates to a micro-electro-mechanical switch assembly including a substrate, an electrode disposed on a portion of the substrate, a dielectric layer disposed on at least a portion of the electrode, a metal layer disposed on at least a portion of the dielectric layer, and a flexible membrane having first and second ends supported at spaced locations on the substrate base, where the flexible membrane is configured to move from a default position to an actuated position in response to a preselected switching voltage applied between the flexible membrane and the electrode, and where, in the actuated position, the flexible membrane is in electrical contact with the metal layer.
