Title: Electroluminiscent conjugated polymers modified with high eletronegative heterocyclic moieties and their applications in polymeric light emitting diodes
Inventor: CHEN SHOU-AN
IPC: C08G73/08
Filed: 1999-05-13
Granted: 2001-10-21
Abstract: This invention provides a method for syntheses of new electroluminescent conjugated polymers modified with high electronegative heterocyclic groups (such as 1,3,4-oxadiazole-diyl, 1,3,4-thiadiazole-diyl, and 1,2,4-triazole-diyl). These electroluminescent polymers (homopolymers, statistical copolymers or block coplymers) are obtained by polymerization of bis(halomethyl) arenes modified with heterocyclic groups via the Wessling precursor route, Gilch side chain route, Wittig reaction or Wittig-Hornor reaction. By a proper selection of the monomers and their ratios in the polymerization, the emissive polymers (fully conjugated or limited conjugating length) covering the full visible range even extending to the near-IR range can be prepared. The polymeric light emitting diodes (PLED) with these materials as emissive layer or electron transport layer have high external quantum efficiency and can be used as indicators and displays for cellular phones, pagers, portable computer, wristwatch, toys, etc.

Title: Data display device and method for request of data update
Inventor: LIOU WEN-SHAN
IPC: H04M1/72403
Filed: 1999-06-04
Granted: 2001-07-01
Abstract: The data display device of the present invention can have bi-directional message transmission with a remote service station in the form of wireless or wireline communication. It can follow the data currently displayed on the screen and selectively transmit the data request signal to a service station to request for the updated data of the transmitted portion in the service station. Thus, the service station can significantly lower the amount of transmitted data and lower the load on bandwidth. When the data request signal is transmitted to a service station, the request for the service station to transmit the updated data scope with order sequence contains the data scope of the screen display.

Granted: 2002-12-21
Abstract: An arrangement and a method are described for the transmission of address, instruction and/or data telegrams from a control unit to (at least) one controlled unit and for the return of a respective reception acknowledge signal from the controlled unit (units) to the control unit in response to each address, instruction and/or data telegram, the reception acknowledge signal signalling the control unit the correct transmission of the relevant address, instruction and/or data telegram. In order to configure a device and a method of this kind in such a manner that limited quantities of data can be transmitted to the control unit also without incorporating bus transmitter stages in the controlled units, according to the invention in (at least) one controlled unit the reception acknowledge signal in response to one of the address, instruction and/or data telegrams is suppressed, exclusively in dependence on a selectable parameter of the operating state of the controlled unit, also in the case of correct transmission of the address, instruction and/or data telegram; the control unit in that case is always signaled an incorrect transmission and the non-arrival of a reception acknowledge signal given in response to said address, instruction and/or data telegram in the control unit is evaluated as an information signal giving information about the selectable parameter of the operating state of the controlled unit.

Title: Self ionized plasma for sputtering copper
Inventor: CHIANG TONY P
IPC: C23C14/04
Filed: 2000-10-05
Granted: 2002-04-21
Abstract: A DC magnetron sputter reactor for sputtering copper, its method of use, and shields and other parts promoting self-ionized plasma (SIP) sputtering, preferably at pressures below 5 milliTorr, preferably below 1 milliTorr. Also, a method of coating copper into a narrow and deep via or trench using SIP for a first copper layer. SIP is promoted by a small magnetron having poles of unequal magnetic strength and a high power applied to the target during sputtering. The target power for a 200 mm wafer is preferably at least 10 kW; more preferably, at least 18kW; and most preferably, at least 24 kW. Hole filling with SIP is improved by long-throw sputtering in which the target-to-substrate spacing is at least 50% of substrate diameter, more preferably at least 80%, most preferably at least 140%. The SIP copper layer can act as a seed and nucleation layer for hole filling with conventional sputtering (PVD) or with electrochemical plating (ECP). For very high aspect-ratio holes, a copper seed layer is deposited by chemical vapor deposition (CVD) over the SIP copper nucleation layer, and PVD or ECP completes the hole filling. The copper seed layer may be deposited by a combination of SIP and high-density plasma sputtering. For very narrow holes, the CVD copper layer may fill the hole. Preferably, the plasma is ignited in a cool process in which low power is applied to the target in the presence of a higher pressure of argon working gas. After ignition, the pressure is reduced, and target power is ramped up to a relatively high operational level to sputter deposit the film.
