    摘要: A system and method are provided for thermal dissipation from a heat producing electronic device. The system includes a substrate for fabricating integrated circuits, the substrate having a first face and a second face. The second face is disposed substantially parallel to the first face having an electronic device disposed therein. A metallized crack stop is disposed in the first face surrounding the electronic device. A plurality of first metal conduits extend through the substrate from the second face thereof to the crack stop, wherein each first metal conduit is in thermal contact with the crack stop to provide a thermal drain from the electronic device to the second face.

    摘要: A method of fabricating micro-electromechanical switches (MEMS) integrated with conventional semiconductor interconnect levels, using compatible processes and materials is described. The method is based upon fabricating a capacitive switch that is easily modified to produce various configurations for contact switching and any number of metal-dielectric-metal switches. The process starts with a copper damascene interconnect layer, made of metal conductors inlaid in a dielectric. All or portions of the copper interconnects are recessed to a degree sufficient to provide a capacitive air gap when the switch is in the closed state, as well as provide space for a protective layer of, e.g., Ta/TaN. The metal structures defined within the area specified for the switch act as actuator electrodes to pull down the movable beam and provide one or more paths for the switched signal to traverse. The advantage of an air gap is that air is not subject to charge storage or trapping that can cause reliability and voltage drift problems. Instead of recessing the electrodes to provide a gap, one may just add dielectric on or around the electrode. The next layer is another dielectric layer which is deposited to the desired thickness of the gap formed between the lower electrodes and the moveable beam that forms the switching device. Vias are fabricated through this dielectric to provide connections between the metal interconnect layer and the next metal layer which will also contain the switchable beam. The via layer is then patterned and etched to provide a cavity area which contains the lower activation electrodes as well as the signal paths. The cavity is then back-filled with a sacrificial release material. This release material is then planarized with the top of the dielectric, thereby providing a planar surface upon which the beam layer is constructed.

    摘要: Methods of fabricating a passive element and a semiconductor device including the passive element are disclosed including the use of a dummy passive element. A dummy passive element is a passive element or wire which is added to the chip layout to aid in planarization but is not used in the active circuit. One embodiment of the method includes forming the passive element and a dummy passive element adjacent to the passive element; forming a dielectric layer over the passive element and the dummy passive element, wherein the dielectric layer is substantially planar between the passive element and the dummy passive element; and forming in the dielectric layer an interconnect to the passive element through the dielectric layer and a dummy interconnect portion overlapping at least a portion of the dummy passive element. The methods eliminate the need for planarizing.

    摘要: A chemical composition and method for providing uniform and consistent etching of gate stacks on a semiconductor wafer, whereby the composition includes an etchant and an added ballast gas added. The gate stacks are formed using this combined etchant and ballast gas composition. The ballast gas may either be similar to, or the equivalent of, a gaseous byproduct generated within the processing chamber. The ballast gas is added in either an overload amount, or in an amount sufficient to compensate for varying pattern factor changes across the water. This etchant and added ballast gas form a substantially homogeneous etchant across the entire wafer, thereby accommodating for or compensating for these pattern factor differences. When etching the wafer using this homogeneous etchant, a passivation layer is formed on exposed wafer surfaces. The passivation layer protects the lateral sidewalls of the gate stacks during etch to result in straighter gate stacks.
