Inventor: FRITIGER WILLIAM A
IPC: H01L21/683
Filed: 1991-06-06
Abstract: Apparatus for clamping a workpiece, for example clamping a semiconductor wafer in a vacuum processing chamber wherein an ion beam is applied to the wafer is provided. In one embodiment, the apparatus includes an electrically conductive platen, a resilient, thermally-conductive dielectric layer affixed to the platen and one or more conductive wires positioned on the clamping surface. The wires protrude at least slightly above the clamping surface except when the wafer is clamped thereon. A clamping voltage is applied between the wires and the platen to firmly clamp the wafer against the clamping surface and depress the wires into the resilient dielectric layer. The clamping voltage preferably comprises a bipolar square wave in the frequency range of less than one Hz to 300 Hz and having a switching rate of about 1000 volts per millisecond or less to limit charging current to the wafer and thereby prevent arcing. In another embodiment, a three-phase wafer clamping apparatus includes a platen divided into three electrically-isolated sections. One phase of a three-phase clamping voltage is connected to each of the platen sections. In the three-phase configuration, the wafer charging current is very small, and the clamping force is essentially constant.

Abstract: A suitable inert thermal gas such as argon is introduced onto the backside of wafers being processed in a CVD reactor during the deposition of tungsten or other metals and silicides, to avoid deposition of material on the backside of the wafers being processed. Each process station includes a gas dispersion head disposed over a platen. The platen has a circular depression for receiving a wafer, and an annular groove provided in the floor of the depression, near the wall thereof. Heated and pressurized backside gas is introduced into the groove so that the wafer is maintained in a position above the floor of the depression but still within it. In this manner, backside gas vents from beneath the edge of the wafer on the platen and prevents the process gases from contacting the wafer backside. The backside gas is also used for levitating the wafer in a transfer region above the platen, so that the wafer can be transported to or from the platen with a suitable wafer transfer mechanism. One suitable transfer mechanism is a multi-armed spindle, the arms being respective pairs of tines. Another suitable transfer mechanism is a removable structure in which the platens are provided with respective heaters, and the platen-heater assemblies are supported by respective tubes from a central support block. Gas and electrical power are furnished to the platen-heater assemblies from the central support block.

Abstract: An apparatus for pressurised screening of a fibre/liquid suspension to separate the fibrous fraction into an accepts portion and a rejects portion, has a housing (60) having an inlet (120) with a trap (90) for heavy and large material, an accepts outlet (110), a rejects outlet (100), and a dilution liquid inlet (105). A hollow cylindrical screen (10) having an open top and bottom communicates with a fibrous suspension inlet chamber (70) and a rejects outlet chamber (80). Accepts fibres in the suspension pass through apertures (15) in the screen to an accepts chamber (75) and are discharged through the accepts outlet. Rejects discharge through the rejects chamber. A rotor (30) having at least four regions, a closed top, and a bottom mounted drive mechanism (150) is coaxially mounted within the screen. Hydrodynamic pulses are induced in the suspension in the screening region by a pattern of bumps and/or depressions (36, 38) impressed upon the rotor surface. The fibrous suspension is maintained at a relatively constant consistency within the screening region by the pumping action of the rotor and by providing dilution liquid to counteract thickening of the suspension. A dynamic bar screening device (40) directs stones and other large objects out of the fluid stream and into an annular trap and also deflocculates the suspension.

Abstract: A simplified method to produce recombinant adeno-associated virus (AAV) vectors is described. The procedure involves the use of chimeric plasmids which incorporate the Epstein Barr nuclear antigen (EBNA) gene, the latent origin of replication of Epstein Barr Virus (oriP), and a recombinant AAV genome. The chimeric plasmids themselves are also a part of the present invention. These EBV/AAV plasmids are maintained as multicopy extra-chromosomal elements in cells, such as human 293 cells. Permanent cell lines carrying these EBV/AAV plasmids are induced to produce large amounts of recombinant AAV virus upon addition of wild-type, adeno-associated virus helper functions. Recombinant AAV vectors produced in this manner are capable of transducing exogenous genes into other human cell lines and exhibit all of the attributes of viral elements produced by conventional methods.

Abstract: The reproduction characteristics, particularly the C/N ratio of a reproduced signal of an optical recording medium are deteriorated by an unevenness or deformation of an optical recording layer due to a convex or concave (i.e. the guide track) configuration of an underlying guide means formed on the surface of the substrate. This deterioration can be prevented by disposing a planalization layer under the recording layer, but the planalization layer lowers the efficiency of the servo tracking. This lowering of servo tracking efficiency is prevented by insertion of a dielectric layer between the planalization layer and the guides.

Abstract: The invention relates to a process for the production of asphalt mixtures using crude asphalt, in which the latter is mixed with mineral substances and, optionally after addition of hot bitumen, heated until a homogeneous mixture which is readily processable is formed. The object of the present invention is to prepare a mixture of this type in which the product from the heating has a minimised hydrocarbon content. This is achieved by classifying the starting material, comprising the crude asphalt and/or the mineral substances, before mixing into a coarse fraction and a fine fraction, and initially heating only the coarse fractions, while the fine fractions, optionally together with hot bitumen, are added at the end of the heating. An apparatus for carrying out the process provides for the arrangement of a classifier (2) before the feed into the warming device (5) for the crude asphalt, the connection for the fine fraction (3) of the crude asphalt being connected via a transport device (23) to a metering zone (13) in a mixing device (8) downstream of the warming device (5), while the connection for the coarse fraction (4) runs, optionally via a further transport device (16), into the warming device. <IMAGE>

Abstract: Data processing system (10) comprising means for converting an input signal into an output signal with the aid of a non-linear function formed piecewise. From the input signal, there is determined (20) a plurality of combinations of the input signal with various coefficients. These combinations are then subjected (22) to the action of a simple non-linear function in order to supply several contributions which are then combined linearly (24) in order to supply the output signal. Hence, from combinations output by a simple non-linear function, it is possible to obtain a complex non-linear function. This can be used for the calculation of non-linear activation functions of a neural network. Application: neural networks, non-linear controllers. <IMAGE>
