    Abstract: Es werden Strukturen mikroelektro-mechanischer Systeme (MEMS-Strukturen), Herstellungsverfahren und Entwurfsstrukturen bereitgestellt. Das Verfahren zum Bilden einer MEMS-Struktur schließt ein Bilden fester Aktuator-Elektroden (115) und eines Kontaktpunkts auf einem Substrat ein. Das Verfahren schließt außerdem ein Bilden eines MEMS-Balkens (100) über den festen Aktuator-Elektroden und dem Kontaktpunkt ein. Das Verfahren schließt außerdem ein Bilden eines Arrays von Aktuator-Elektroden (105') in Ausrichtung mit Abschnitten der festen Aktuator-Elektroden ein, die so groß und so dimensioniert sind, dass sie verhindern, dass der MEMS-Balken nach wiederholter periodischer Betätigung auf den festen Aktuator-Elektroden nachgibt. Das Array von Aktuator-Elektroden wird in direktem Kontakt mit mindestens einem von einer Unterseite des MEMS-Balkens und einer Oberfläche der festen Aktuator-Elektroden gebildet.

    Abstract: A method of forming at least one Micro-Electro-Mechanical System (MEMS) cavity (60b) includes forming a first sacrificial cavity layer (18) over a wiring layer (14) and substrate (10). The method further includes forming an insulator layer (40) over the first sacrificial cavity layer. The method further includes performing a reverse damascene etchback process on the insulator layer. The method further includes planarizing the insulator layer and the first sacrificial cavity layer. The method further includes venting or stripping of the first sacrificial cavity layer to a planar surface for a first cavity (60b) of the MEMS.

    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.
