Abstract: A method of fabricating an encapsulated micro electro-mechanical system (MEMS) and making of same that includes forming a dielectric layer, patterning an upper surface of the dielectric layer to form a trench, forming a release material within the trench, patterning an upper surface of the release material to form another trench, forming a first encapsulating layer that includes sidewalls within the another trench, forming a core layer within the first encapsulating layer, and forming a second encapsulating layer above the core layer, where the second encapsulating layer is connected to the sidewalls of the first encapsulating layer. Alternatively, the method includes forming a multilayer MEMS structure by photomasking processes to form a first metal layer, a second layer including a dielectric layer and a second metal layer, and a third metal layer. The core layer and the encapsulating layers are made of materials with complementary electrical, mechanical and/or magnetic properties.

Abstract: A dielectric material formed by contacting a low dielectric constant polymer with liquid or supercritical carbon dioxide, under thermodynamic conditions which maintain the carbon dioxide in the liquid or supercritical state, wherein a porous product is formed. Thereupon, thermodynamic conditions are changed to ambient wherein carbon dioxide escapes from the pores and is replaced with air.

Abstract: A micro electromechanical switch has a guidepost formed upon a substrate. A signal transmission line is formed on the substrate, with the signal transmission line having a gap and forming an open circuit. The switch further includes a switch body having a via opening formed therein, with the switch body being movably disposed along an length defined by the guide post. The guidepost is partially surrounded by the via opening.
