Title: Method for etching dielectric layer
Inventor: LIOU BING-LIANG
IPC: H01L21/76
Filed: 1999-10-06
Granted: 2003-02-11
Abstract: The present invention provides an etching method of dielectric layer, in which the problems of edge loss and pattern deformation generated when etching the dielectric layer to form openings in the conventional process can be reduced by using two-step etching method and the control of etching selection rate. The invented method contains the following steps. At first, a semiconductor substrate is provided, in which a dielectric layer is formed on the substrate and a patterned mask layer is provided on the dielectric layer. Then, by using the mask layer as the etching mask, the first etching step is conducted onto the dielectric layer. By using the mask layer as the etching mask, the second etching step is performed onto the dielectric layer. The first etching step of etching dielectric layer has a higher etching selectivity relative to the mask layer than the second etching step. Additionally, in a better executed-example, a step of stripping anti-reflection layer can be included before the execution of the first etching step mentioned above, and the anti-reflection layer is located between the mask layer and the dielectric layer.

Title: Tire pressure monitoring device and method
Inventor: KATOU MITIYA
IPC: G08C19/00
Filed: 2000-01-28
Granted: 2001-10-01
Abstract: Each transmitter installed on vehicle's tire will generate a variable value, which is based on the pre-defined sequence in each data transmission of the transmitter to update. The current value of the variable follows other data for being transmitted to a receiver. The receiver determines if a receiving failure occurs prior to receiving current data based on whether the variable value contained in the received data is updated with the pre-defined sequence. The receiver will conclude the communication failure occurrence when the receiving failure count is equal to or greater than a upper limit, and will conclude no communication failure occurrence when the receiving failure count is less than the upper limit. As such the detection of communication failure can be even simpler and more reliable.

Title: A stable plasma process for etching of films
Inventor: NALLAN PADMAPANI
IPC: H05H1/46
Filed: 2000-09-22
Granted: 2002-01-11
Abstract: In accordance with the present invention, process parameters are controlled to provide a stable etch plasma. We have discovered that it is possible to operate a stable plasma with a portion of the power deposited to the plasma being a capacitive contribution and a portion of the power deposited being an inductive contribution. In particular, a stable plasma may be obtained within two process regions. In the first region, the gradient of the capacitive power to the power applied to the inductively coupled source for plasma generation [∂ Pcap/∂ PRF] is greater than 0. In the second region, plasma stability is controlled so that [∂ Pcap/∂ PRF] is less than 0 and so that Pcap, << PRF. Typically, the magnitude of Pcap is less than about 10% of the magnitude of PRF. In addition, in a plasma processing apparatus having a dual power control, at a given application of power to the plasma generation source, the stability of the plasma is extended by increasing the pressure in the etch process chamber. This enables operation of the etch process using lower power application for plasma generation. The stable plasma operating regime is overlaid upon other process parameters to obtain the desired etch results, to provide a reliable manufacturing process. Operation of the etch process in a stable plasma region enables use of a timed etch end point. For example, during etching of a silicon-containing layer, it is possible to use an etchant plasma which provides rapid etching and etch selectivity relative to adjacent layers during a first, timed etch portion of the etch process, and a different etchant plasma during a final emissions monitored etching to an underlying substrate interface. In addition, the stable plasma assists in the etching of doped and undoped silicon and polysilicon substrates at substantially the same rate, while providing for a clean etch process.

Abstract: The present invention relates to a quantitative method for stopping investment loss in margin transaction, especially relates to a quantitative method that uses an self-adjustable index of time and market fluctuation to stop the investment loss. The steps in the present invention include choosing a financial commodity to be quantified, getting a value of initial margin per lot for the financial commodity and a specific integral number for a price; judging operation mode for the financial commodity; selecting an operating parameter; using the value of initial margin per lot for the financial commodity, the specific integral number for the price and the operating parameter to calculate a stop price to be an operating index. When the price of the financial commodity touches the operating index, the operation can be further conducted according to the operation mode in order to avoid the increase in investment loss. With the help of optimization process for a variety of trading systems, the risk of investment can be reduced and the profit therefore can be elevated.

Title: Multi element, multi color solid state LED/laser
Inventor: DENBAARS STEVEN P
IPC: H01L33/08
Filed: 2000-11-17
Granted: 2002-01-11
Abstract: A light emitting diode (LED) (10) grown on a substrate 16 doped with one or more rare earth or transition element. The dopant ions absorb some or all of the light from the LED's active layer (11), pumping the electrons on the dopant ion to a higher energy state. The electrons are naturally drawn to their equilibrium state and they emit light at a wavelength that depends on the type of depant ion. The invention is particularly applicable to nitride based LEDs (10) emitting UV light and grown on a sapphire substrate (16) doped with chromium. The chromium ions absorb the UV light, exciting the electrons on ions to a higher energy state. When they return to their equilibrium state they emit red light and some of the red light will emit from the LED's surface. The LED (20) can also have active layers (21, 22, 23) that emit green and blue and UV light, such that the LED emits green, blue, red light and UV light which combines to create white light. Alternatively, it can have one active layer (35) and grown on a sapphire substrate (38) doped with Cr, Ti, and Co such that the substrate (38) absorbs the UV light and emits blue, green, and red light. The invention is also capable of providing a tunable LED (20) over a variety of color shades. The invention is also applicable to solid state lasers (76) having one or more active layers (77) emitting UV light with the laser grown on a sapphire substrate (80) doped with one or more rare earth or transition elements.

Title: Aggregate-free urate oxidase for preparation of non-immunogenic polymer conjugates
Inventor: KELLY SUSAN J
IPC: A61K38/00
Filed: 2001-02-06
Granted: 2010-03-21
Abstract: A naturally occurring or recombinant protein, especially a mutein of porcine urate oxidase (uricase), that is essentially free of large aggregates can be rendered substantially non-immunogenic by conjugation with a sufficiently small number of strands of polymer such that the bioactivity of the protein is essentially retained in the conjugate. Such conjugates are unusually well suited for treatment of chronic conditions because they are less likely to induce the formation of antibodies and/or accelerated clearance than are similar conjugates prepared from protein preparations containing traces of large aggregates.
