Patent EP-0546718-A2 (EP)
Inventor: MILLER GLEN PAUL
IPC: C08K5/06
Filed: 1992-11-25
Abstract: This invention relates to novel compositions of matter, certain derivatized fullerenes, and the process of making them. The derivatized fullerenes of the present invention contain substituent groups in even numbers and are produced by contacting the fullerenes with an oxidizing agent, such as a strong acid or superacid, then adding a suitable nucleophilic quenching agent such as an alcohol, thiol or aromatic that contains the substituent group to be added. Terminal 1,y-difulleroxyalkanes result from trapping with terminal 1,y-diols where y is the number of carbon atoms in the diol. Odd numbered derivatized fullerenes are produced by heating the even number derivatized fullerenes thus produced. The compositions may be used as crosslinking agents in polymers, core building blocks for star polymers, and stiffening agents in polymers and polymer blends.

Abstract: A semiconductor device such as a Schottky-barrier rectifier diode is disclosed which has a barrier electrode formed on a semiconductor substrate of gallium arsenide or the like. Formed around the barrier electrode is an annular resistive layer, typically of titanium oxide, creating a Schottky barrier at its interface with the semiconductor substrate. The resistive layer has a sheet resistance of more than 10 kilohms per square. In order to prevent preliminary breakdowns from taking place at the peripheral part of the resistive layer before final breakdown of the device, the sheet resistance of the resistive layer is made higher as it extends away from the barrier electrode. For the ease of manufacture, the resistive layer can be divided into two or more annular regions of distinctly different sheet resistances.

The grid (138) is positioned from the cathode (136) by the distance an emitted electron from the cathode (136) can travel in a quarter cycle of the r.f. signal. Outer (202) and inner (204) coaxial metal tubes forming a resonant line of a signal coupler (143) are respectively connected to the grid (138) and cathode (136) so electrons passing through the grid (138) are in bundles in an interaction region (20) between an accelerating anode (18) and the grid (138). Ferrite tiles (42) absorb r.f. fields in the interaction region (20). In one embodiment a signal coupling loop (12) is between metal tubes (202,204) at an end of the tubes spaced 3λ/4 from the grid (138) and cathode (136). In a second embodiment the coupler (143) includes a low voltage coaxial line (110) having an inner conductor (112) connected to a first metal face (125), spaced from a second opposed metal (134) face by a solid dielectric (140). The coaxial outer conductor (114) is connected to a third metal face (128), spaced from a fourth opposed metal face (142) by the solid dielectric (140). The third (128) and fourth (142) faces surround the first (125) and second (134) faces. The first (115) and third (128) faces are at DC ground potential while the second (134) and fourth (142) faces are at high negative DC voltages. The second (134) and fourth (142) faces are respectively at common ends of interior (204) and exterior (202) coaxial metal tubes forming a λ/2 coupler (143). Other ends of the tubes (202,204) are connected to the cathode (136) and grid (138). Bias leads (190,194) for the grid (138) and cathode (136) are connected to the exterior (202) and interior (204) tubes at positions λ/4 from the grid (138) and cathode (136), while a heater lead (196) goes through the interior tube (204) at a position λ/4 from the grid (138) and cathode (136).

Abstract: A method and system are provided for determining a set of tables 62, 64 from which data can be redistributed between nodes 61, 63 in a parallel database. First, a list of candidate tables from those stored in the memories associated with a plurality of nodes in the parallel database is established. The list is ordered according to a workload of each of the candidate tables. Next, each of the candidate tables is tested to determine whether it can be scanned at each of the plurality of nodes at which the candidate table is stored within a predetermined time period. Any candidate table which can be scanned within the predetermined time period is added to the set of tables from which data can be redistributed. Once the set of tables for redistribution are established, data sets, or buckets, within the redistribution tables are selected. The selected buckets are redistributed from the plurality of nodes to a receiving node 71. The receiving node is a new node to the parallel database system or an underutilized node in the parallel database system.

Abstract: A playback signal is supplied to a delay amplifier and a noise comparator. The delayed playback signal is supplied to a comparator, which compares the delayed playback signal with the playback signal and provides a first comparison signal to a pulse adjustment circuit. The noise comparator compares the playback signal with threshold signals and provides a second comparison signal to the pulse adjustment circuit. The pulse adjustment circuit generates the peak detection signal at each point when the signal level of the first comparison is inverted, and determines the peak detection signal to be invalid when the signal level of the playback signal falls within the range between the threshold signals. A read signal is generated based on the valid peak detection signal.

Abstract: A method and apparatus for removing particulate contaminants from a semiconductor wafer are disclosed. A wafer 10 is held in a wafer holder 12 at cleaning station 14. Cleaning station 14 has a rinse fluid supply system 18 which supplies, e.g. deionized water, to the wafer surface during particle removal. A cleaning pad 20 is mounted on a platen 22, substantially in the plane of wafer 10. Platen 22 is coupled to a drive mechanism 24, which may for example be an electric motor, and drive mechanism 24 is coupled to station 14 by an engagement mechanism 26 which provides vertical displacement to engage pad 20 and wafer 10 for particle removal, and also provides a controlled pad contact pressure during particle removal. In operation, rinse fluid from 18 is supplied to slowly rotating wafer 10, while pad 20 is rotated, preferably at 200 to 600 rpm, and contacted with wafer 10. High pad speed appears to be particularly beneficial to cleaning, with pad contact pressure and contact time apparently being secondary effects which at least decrease wafer-to-wafer variances in the cleaning process.
