    Abstract: A method and structure that provides a battery (420) within an integrated circuit for providing voltage to low-current electronic devices (900) that exist within the integrated circuit. The method includes Front-End-Of-Line (FEOL) processing for generating a layer of electronic devices (900) on a semiconductor wafer (402), followed by Back-End-Of-Line (BEOL) integration f or wires the electronic devices together to form completed electrical circuits of the integrated circuit. The BEOL integration includes forming a multilayered structure of wiring levels on the layer of electronic devices. Each wiring level includes conductive metallization (e.g., metal-plated vias, conductive wiring lines, etc.) embedded in insulative material. The battery (420) is formed during BEOL integration within one or more wiring levels, and the conductive metallization (432,434,442,444) conductively couples positive (42 4) and negative (422) terminals of the battery to the electronic devices (900). The battery (420) may have several different topologies relative to the structural and geometrical relationships among the battery electrodes and electrolyte. Multiple batteries may be formed within one or more wiring levels, and may be conductively coupled to the electronic devices. The multiple batteries may be connected in series or in parallel.

    Abstract: A method of forming a Micro-Electro-Mechanical System (MEMS) includes forming a lower electrode on a first insulator layer within a cavity of the MEMS. The method further includes forming an upper electrode over another insulator material on top of the lower electrode which is at least partially in contact with the lower electrode. The forming of the lower electrode and the upper electrode includes adjusting a metal volume of the lower electrode and the upper electrode to modify beam bending.

    Abstract: Verfahren zum Ausbilden eines Arms eines mikroelektromechanischen Systems (MEMS), aufweisend: Ausbilden einer unteren Elektrode (38) auf einer Opferschicht (18); Ausbilden einer Isolatorschicht (40) auf der unteren Elektrode (38); und Ausbilden einer oberen Elektrode (44) über dem Isolatormaterial (40) auf der Oberseite der unteren Elektrode (38), wobei die obere Elektrode (44) zumindest teilweise mit der unteren Elektrode (38) in Kontakt steht, wobei die untere Elektrode (38) und die obere Elektrode (44) aus demselben Material ausgebildet werden. wobei das Ausbilden der unteren Elektrode und der oberen Elektrode ein Ausgleichen eines Metallvolumens der unteren Elektrode und der oberen Elektrode derart aufweist, dass die untere Elektrode (38) eine um einen Prozentsatz geringere Fläche als die obere Elektrode (44) aufweist und die Dicke der unteren Elektrode um einen Prozentsatz erhöht wird, um das Metallvolumen der Elektroden auszugleichen, sodass die Metallvolumina der unteren Elektrode (38) und der oberen Elektrode (44) übereinstimmen.

    Abstract: A method of forming at least one Micro-Electro-Mechanical System(MEMS) cavity includes forming a first sacrificial cavity layer over a lower wiring layer. The method further includes forming a layer. The method further includes forming a second sacrificial cavity layer over the first sacrificial layer and in contact with the layer. The method further includes forming a lid on the second sacrificial cavity layer. The method further includes forming at least one vent hole in the lid, exposing a portion of the second sacrificial cavity layer. The method further includes venting or stripping the second sacrificial cavity layer such that a top surface of the second sacrificial cavity layer is no longer touching a bottom surface of the lid, before venting or stripping the first sacrificial cavity layer thereby forming a first cavity and second cavity, respectively.

    Abstract: A method for fabricating a dual damascene coper interconnect which electrically contacts a damascene tungsten wiring level (190) comprising forming a first layer on a semiconductor substrate, a silicon nitride layer (140) on the first layer, and a silicon dioxide layer (150) on the silicon nitride layer. The first layer includes damascene tungsten interconnect regions separated by electrically insulating material. A continuous space (630) is formed by etching two contact throughs (910) through the silicon dioxide and silicon nitride layers to expose damascene tungsten interconnect regions, and by etching a top portion of the silicon dioxide layer between the two contact throughs. A reduced-height portion of the silicon dioxide layer remains between the two contact troughs. The continuous space is filled with damascene copper. The resulting dual damascene copper interconnect electrically contacts the exposed damascene tungsten interconnect regions.
