Title: Method of reducing switching noise in a power distribution system by external coupled resistive terminators
Inventor: CHANG TSUN-HSU
IPC: H03K17/04
Filed: 2003-03-18
Granted: 2004-03-21
Abstract: Voltage fluctuations, especially due to a resonant effect of a power distribution system, result in serious timing skews in a high-speed digital system. Adding extra resistive loadings for coupling out the noise into external terminations will reduce a quality factor of the power distribution system, which will effectively minimize the noise accumulation. The external coupled resistive terminators are preferably formed on positions of a microstrip resonator where relatively high noise fluctuations occur. Each of the external coupled resistive terminators may be formed of a resistor, a transmission line with a resistor at one end, a lossy transmission line with an open circuit at one end, or a quarter-wavelength lossy transmission line. Simulation results indicate that the maximum voltage fluctuations are suppressed from 750 mV to 150 mV at a resonant frequency and about 50% for an overall range of the operating frequencies.

Granted: 2006-07-01
Abstract: A method to clean and maintain the rotational etcher is disclosed, wherein the physical characteristic that deionized (DI) water splashes around after being dropped onto the rotational wafer is utilized, and a cleaning program specially designed is associated to clean different locations of the cleaning chamber by varying different parameters. For example, to clean a single etching chamber, vary the rotational speed of wafer at the locations in the chamber, so that the cleaning liquid instilled can splash onto the inner wall of the chamber with different angles. In addition, the falling spots of cleaning liquid on the wafer can also be varied to increase the splashing angles. To clean the outer sidewall of the etching chamber, move the wafer back and forth among different etching chambers and vary the rotational speed, so that the cleaning liquid on the wafer can splash onto the outer sidewall of the etching chamber with different angles. By associating with programs of the present invention, cleaning work can execute automatically anytime, which has the advantages of saving time and labor.
