    摘要: Method for forming a semiconductor device having an capacitor, where the capacitor is in-laid in a cavity formed in the semiconductor substrate and part of a high density memory. One embodiment first forms a bottom electrode in the cavity and then fills the cavity with a sacrificial layer to allow chemical mechanical polishing (CMP) of at least one of the capacitor electrodes. After removing portions of the bottom electrode and portions of the sacrificial layer, a dielectric layer is formed. A top electrode is then formed over the dielectric layer. The dielectric layer so formed isolates the bottom electrode from the top electrode preventing shorting and leakage currents. In one embodiment, a single top electrode layer is formed for multiple bottom electrodes, reducing the complexity of the memory circuit.

    摘要: An improved swimming pool cleaner of the type for submerged random travel generally along the floor and sidewalls of a swimming pool to dislodge and collect debris. The pool cleaner comprises a frame and associated housing through which a suction mast extends with a collection bag mounted at the upper end thereof. First and second wheels are mounted for rotation on a common axis on opposite sides of the housing forwardly of the suction mast, and third and fourth wheels are mounted for rotation on a common axis on opposite sides of the housing rearwardly of the suction mast. The first and second wheels are driven by a water-powered drive train within the housing, and the third and fourth wheels are mounted for freewheeling rotation. A forward end of an upper surface of the housing has a substantially linear sloping portion to reduce the tendency of the cleaner to lift off the submerged surfaces of the swimming pool as the first and second wheels propel the cleaner in the forward direction.

    摘要: The present invention is a process for forming a lower capacitor electrode. Specifically, an oxygen tolerant bottom electrode layer (312) is formed over a conductive plug (216). A dielectric layer (420) is deposited and partially removed in order to form an inlaid bottom electrode structure. A capacitor dielectric (810) such as BST is formed over the lower electrode (310). The upper electrode (812) is formed over the capacitor dielectric (810) and the resulting stack is patterned in order to form a final capacitive device (916). In another embodiment of the present invention, a hardmask is formed over the bottom electrode (310) and removed prior to the capacitor dielectric (810) being formed.

    摘要: An article made from a fabric layer permeable to a first liquid such as water, blood or urine. The article has one side that repels the liquid and another side which absorbs the liquid. The article can be disposed of by heating in a selected liquid, which dissolves or disperses the article. The article may also have a plastic layer affixed thereto to provide additional impermeability. Two of the fabric layers may be affixed with the impermeable sides facing each other to provide an article capable of absorbing fluids from both sides, yet preventing fluids from penetrating from one side to the other. An optional plastic layer may be juxtaposed between the facing sides to provide a further fluid barrier. A method of disposing of such articles comprising contacting the articles with a sufficiently hot second liquid for a sufficient period of time to disperse or dissolve substantially the articles.

    摘要: A metallic interconnect includes a fuse portion that is readily vaporized upon exposure to the radiant energy of a laser. A layer of optically absorptive material is formed on top of an aluminum based metallic interconnect and together they are formed by a photolithographic and etch technique into a fuse portion. A low energy laser having a Gaussian energy distribuution focused on the absorptive layer produces heat in the absorptive layer. The heat is transferred to the underlying aluminum based interconnect. The concentration of energy made possible by the absorptive layer allows the low energy laser to blow the fuse thereby producing an electrical open in the interconnect without damaging surrounding silicon substrate and/or polysilicon structures below or nearby the metal fuse.

    摘要: A thin film inductive transducer is shown comprising three magnetic layers (10, 11, 12) deposited on a slider substrate (13) for perpendicular recording of magnetic transitions on a movable magnetic medium. Two magnetic closures are provided. One is defined by electrical contact of one outer magnetic layer (12 or 10) with the intermediate magnetic layer (11 or 11') within the area bounded by conductive turns (a-h) of single layer coil (19 or 19'). The other is defined by electrical contact (10, 12 or 10', 12') outboard of the conductive turns (a-h). Magnetic transitions may be read by conventional peak detection techniques because the disclosed transducer has three pole tips (P1, P2, P3), the central one P2 of which is approximately 33-40% of the thickness of the outer pole tips (P1, P3). To avoid "wrap-around", the pole tips (P1, P2, P3) are progressively narrower in width as their distance from the substrate (13) increases.
