Title: A method and system to record digital data in terms of analog signal
Inventor: HOPNER EMIL
IPC: G11B5/00
Filed: 1999-10-08
Granted: 2001-10-21
Abstract: This invention introduces a method to record digital data in terms of analog signals. A binary data file is provided in this method with every multiple bits of data transformed into a numerical value. These multiple bits of data are also called a multi-bit packet. Then, the binary data file is transformed into a symbol data file with each symbol representing the corresponding value. This method further transforms the value of the symbol data file into a potential analog signal file. The potential analog signal file is then processed by the technique of frequency modulation (FM) and recorded in a recording medium. The pulse width of the FM pulse signals is reduced in multiple by utilizing the Slimming Equalization Technology to achieve multiple gain in recording density. When the binary data file needs to be broadcasted, the potential analog signal file is accessed from the recording medium. Then, the potential analog signal file is sampled and transformed back to a symbol data file, which is further transformed back to a binary data file for broadcast. Based on this method, this invention provides a system to record and broadcast a binary data file.

Title: Method for eliminating the bridge short of metal interconnects
Inventor: LIOU JUNG-SHI
IPC: H01L23/48
Filed: 1999-10-19
Granted: 2001-04-11
Abstract: In order to avoid the wire open problem of aluminum metal lead caused by electro-migration effect, a small amount of copper is usually added to eliminate the electromigration effect while depositing aluminum metal layer. However, the copper in the aluminum metal will segregate as the CuAl2 of θ phase and the CuAl2 of θ phase will not be easily removed by etching, and thus the metal bridge short problem is encountered. Furthermore, the CuAl2 of θ phase will also generate electrochemical effect in the processing solution to form voids by melting the aluminum metal. Therefore, the invention uses a rapid cooling method after forming AlCu alloy metal layer to reduce the segregation of θ phase CuAl2 from the copper metal and the grain growth so as to eliminate the bridge short of metal interconnects.

Abstract: A self-refresh oscillator for a semiconductor memory device includes a control signal generator sensing a variation of a potential of an inputted signal and generating a write operation control signal having a predetermined pulse width in accordance with an enable signal enabled when a self-refresh mode starts, a cell emulator feeding back the write operation control signal, performing a data write operation, and discharging an output terminal potential in accordance with a temperature variation, and a comparator selectively enabled according to the enable signal, comparing a first input signal which is an output signal from the cell emulator with a second input signal which is a reference potential, and inputting the output signal to a first input terminal of the control signal generator. As a result, the self-refresh oscillator senses the data loss of the memory cell resulting from the leakage current, and controls a refresh period, thereby minimizing the power consumption in the standby mode.

Title: Method for driving display apparatus, driving circuit, display apparatus and electronic machine
Inventor: YATABE SATOSHI
IPC: G09G3/20
Filed: 2000-11-18
Granted: 2003-09-01
Abstract: In order to suppress power consumption in halftone display, each horizontal scanning period for which one of a plurality of scanning lines is selected is divided into the first and the second half periods. A non-selection voltage for bringing a TFD into a nonconductive state for the first half period and a selection voltage for bringing the TFD into a conductive state for the second half period are supplied as a scanning signal to the scanning line. When an odd scanning line is selected, a right shift modulation method is applied to the pixels located on the relevant scanning line. When an even scanning line is selected, a left shift modulation method is applied to the pixels located on the relevant scanning line. Thus, since only one voltage switching of the data signal Xi per horizontal scanning period is required for white or black display, and only two times of voltage switching are required for halftone display, the power consumption required for voltage switching is reduced.
