    Abstract: PROBLEM TO BE SOLVED: To provide a new micromini electromechanical(MEM) switch. SOLUTION: This MEM switch contains a guide post formed on a substrate. A signal transmission line having a gap to form an open-circuit is produced on the substrate. The switch also contains a switch body internally-provided with a via opening, which is movably-located along the length demarcated by the guide post. The guide post is partially enclosed with the via opening.

    Abstract: PROBLEM TO BE SOLVED: To improve a rigidity of a backend-of-line structure. SOLUTION: The damascene structure of interconnecting multi-level coppers on an integrated circuit chip includes several line conductors which are on the integrated circuit and are separated by dielectric materials having quite low dielectric constant and high elastic modulus. A second flat interconnection layer 18 on the first flat interconnection layer 14, consists of a dielectric film 26 having a higher elastic modulus than that of a dielectric material in the first flat interconnection layer 14, and an electrical conduction via 28 passing through the dielectric film 26. Electrical conduction vias 28 contact line conductors 22 selectively. A third flat interconnection layer 20 on the second flat interconnection layer 18, has several line conductors 22 which are isolated by dielectric materials and contact electrical conduction vias selectively.

    Abstract: A micro-electromechanical (MEM) RF switch provided with a deflectable membrane ( 60 ) activates a switch contact or plunger ( 40 ). The membrane incorporates interdigitated metal electrodes ( 70 ) which cause a stress gradient in the membrane when activated by way of a DC electric field. The stress gradient results in a predictable bending or displacement of the membrane ( 60 ), and is used to mechanically displace the switch contact ( 30 ). An RF gap area ( 25 ) located within the cavity ( 250 ) is totally segregated from the gaps ( 71 ) between the interdigitated metal electrodes ( 70 ). The membrane is electrostatically displaced in two opposing directions, thereby aiding to activate and deactivate the switch. The micro-electromechanical switch includes: a cavity ( 250 ); at least one conductive path ( 20 ) integral to a first surface bordering the cavity; a flexible membrane ( 60 ) parallel to the first surface bordering the cavity ( 250 ), the flexible membrane ( 60 ) having a plurality of actuating electrodes ( 70 ); and a plunger ( 40 ) attached to the flexible membrane ( 60 ) in a direction away from the actuating electrodes ( 70 ), the plunger ( 40 ) having a conductive surface that makes electric contact with the conductive paths, opening and closing the switch.

    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.
