Inventor: COLE JOSEPH
IPC: C23C22/52
Filed: 2003-02-27
Granted: 2007-02-01
Abstract: The invention features and methods and compositions for oxide production on a copper substrate, e.g., a copper or copper alloy substrate, to provide for improved adhesion of copper substrate to polymeric material, e.g., such as used in manufacture of printed circuit boards. The oxide-producing compositions of the invention, which may be either acidic or ammoniacal, comprise (1) a source of Cu++ (Cupric) ions; (2) a source of a primary electrolyte that is non-interactive with copper ions; (3) a Cuprous ligand, e.g., a halide ion, preferably chloride, which also serves as a secondary electrolyte; and (4) an optional organic. Acidic oxide-producing compositions comprise a strong acid as the primary electrolyte. The primary electrolyte of ammoniacal oxide-producing compositions is a non-interactive, ammonium salt of acid, which provides a highly soluble Cupric ammonium salt. The secondary electrolyte of the oxide-producing compositions is selected so as to be compatible with the primary electrolyte.

Title: Common voltage regulating circuit of liquid crystal display device
Inventor: LEE HWA-JEONG
IPC: G09G5/00
Filed: 2003-07-10
Granted: 2007-04-01
Abstract: Disclosed is a common voltage regulating circuit of a liquid crystal display device which can be adjusted by software, comprising: a pulse signal generating means for outputting a pulse width modulation signal in response to up/down signal for adjusting a common voltage; a smoothing means for smoothing a pulse width modulation signal to a direct current level provided from the pulse signal generating means; and an amplifying means for amplifying the signal smoothed by the smoothing means to a predetermined level and then outputting a common voltage signal. Accordingly, since a common voltage can be adjusted by software by means of a surplus pulse width modulation signal generated in an integrated board without installing a separate hardware, the common voltage can be easily adjusted. Further, since a variable resistor has not been used, not only manufacturing cost but also possibility of breakage can be reduced.

Title: Polysilicon etching method
Inventor: SUZUKI TAMITO
IPC: H01L21/8247

Granted: 2005-11-01
Abstract: A polysilicon etching method capable of completely removing polysilicon residues left on the side walls of a protrusion covered with a polysilicon layer after the polysilicon layer is patterned while form anisotropy of the polysilicon layer is retained and the underlying insulating film is left unetched. After a polysilicon layer is deposited over one principal surface of a substrate, covering a protrusion, a resist layer is formed on the polysilicon layer over the protrusion. By using the resist layer as a mask, a plasma etching process is performed to pattern the polysilicon layer and form a gate electrode polysilicon layer. At a first step, the polysilicon layer is etched by using HBr and Cl2 until polysilicon spacer residues appear on the side walls of the protrusion, and at a second step the polysilicon residues are removed by using HBr at a pressure of 5 to 10 mTorr.

Granted: 2005-03-11
Abstract: A digital signal processing system and method applied for color transition, wherein the method has the acts of: performing a differential process on an original chroma signal C to obtain a first order differential C'; taking the absolute value |C'|; performing a difference process on the absolute value |C'| to obtain a second differential Ca'; determining whether the second differential Ca' is a positive signal or a negative signal; wherein based on a determined result, an optimized chroma signal with improved color sharpness is generated by selectively mixing primary, present and delayed chroma signals. Thus, a filter can be effectively avoided of generating poor effects, and the difficulty in implementing a hardware is far lower than a digital filter circuit. Meanwhile, the intensity of its influence on the original signals can be dynamically adjusted. As a result, the invented method has the advantages of high performance, high flexibility and low cost.

Title: Write circuit of double data rate synchronous dram
Inventor: CHO YONG-DEOK
IPC: G11C11/413
Filed: 2004-06-30
Granted: 2006-10-21
Abstract: Provided is a write circuit of a DDR SDRAM, in which a clock domain crossing is generated from a writing driver during a data write operation and a proper data is always transferred to a gio bus line by using the delay of an internal data strobe signal's falling for a certain amount of time as an input data strobe bar signal. Moreover, by using a skew detection circuit, it is possible to detect a skew tDQSS between a clock and a data strobe, and the skew tDQSS is automatically compensated by the skew compensation circuit. From the perspective of a timing error between the clock and the data strobe, therefore, the write operation of the DDR SDRAM has twice the timing margin (0.5 tCK) compared to that of the related art. This means that a stable, high-speed write operation of the DDR SDRAM can be made possible.

Filed: 2004-11-11
Granted: 2012-10-11
Abstract: A method and device for managing resources in shared networks is based on a few basic comparisons between resources and/or thresholds. If an access request is received (202) and there are not enough resources available (204), the request is rejected (212). If there are resources available (204), there is a check to see if the resource is in a congested state (206). If not, then the connection is accepted (210). If the resource is in a congested state (206), then a test is performed (208) to determine whether or not the resources will be assigned to an operator who has already exceeded the assigned utilisation. If it has, then the connection is rejected (212), otherwise it is accepted (210). Preferred embodiments incorporating priority handling, re-negotiations and soft congestion are easily implemented. In a shared UTRAN, the functionalities for managing the radio baseband allocation for a shared Node B are preferably incorporated in the shared RNC.
