Title: Dynamic period detecting method and detector
Inventor: HUNG CHUNG-WEN
IPC: G01R23/02
Filed: 2000-08-25
Granted: 2002-04-11
Abstract: The present invention discloses a dynamic period detecting method and a detector for implementing the method. A zero-crossing detecting method is used to detect a rough period. Then, a weighted average filtering method is used to remove noise, thereby obtaining a precise period value P. The average number for generating the weighted values in the weighted average filtering method can be dynamically adjusted based on the change of the period. Therefore, the detecting method is able to accurately and rapidly detect the period value, and save a large amount of storage space and calculating the time compared with the conventional moving average filtering method.

Title: Quad pumped bus architecture and protocol
Inventor: SINGH GURBIR
IPC: G06F13/36
Filed: 2001-04-18
Granted: 2003-11-01
Abstract: A bidirectional multidrop processor bus is connected to a plurality of bus agents. Bus throughput can be increased by operating the bus in a multi pumped signaling mode in which multiple information elements are driven onto a bus by a driving agent at a rate that is a multiple of the frequency of the bus clock. The driving agent also activates a strobe to identify sampling points for the information elements. Information elements for a request can be driven, for example, using a double pumped signaling mode in which two information elements are driven during one bus clock cycle. Data elements for a data line transfer can be driven, for example, using a quad pumped signaling mode in which four data elements are driven during one bus clock cycle. Multiple strobe signals can be temporarily activated in an offset or staggered arrangement to reduce the frequency of the strobe signals. Sampling symmetry can be improved by using only one type of edge (e.g., either the rising edges or the falling edges) of the strobe signals to identify the sampling points.

Title: Manufacture method for improving uniformity of gate oxide layer
Inventor: CHEN CHI-CHIUN
IPC: H01L21/28
Filed: 2001-05-29
Granted: 2002-06-11
Abstract: This invention provides a manufacture method to improve uniformity of gate oxide layer. During gate oxide layer manufacturing process, due to heat transfer phenomenon, the temperature at the edge of a wafer is generally higher than that in the central part of the wafer and thus poor gate oxide layer uniformity results. The temperature ramp down stage is utilized, in which the gas composition is changed and a minor oxidation is performed on the wafer. Because the wafer's central part dissipates heat with less effectiveness and thus has a higher temperature than that of the wafer edge during temperature ramp down stage, the oxidation rate at the wafer's central part is faster than that of the wafer edge. Therefore, the shortcoming of thicker gate oxide layer at the wafer edge compared with that at the wafer's central part during the gate oxide layer manufacturing can be overcome.

Granted: 2002-10-21
Abstract: In order to keep constant impurity concentration profile in a transition region which is susceptible to the influence of an auto doping phenomenon, a dopant gas of a concentration at which an impurity concentration higher than the auto doping amount is fed to the transition region for shifting the gradient of the impurity concentration profile of the transition region to the higher concentration side. In other words, the impurity concentration profile of the transition region is so preset that the impurity concentration may be sufficiently higher than the auto doping amount estimated. The auto doping amount is limited, even if changed, within an allowable changing range of the gradient impurity concentration profile, so that the characteristics of a semiconductor device made of a silicon epitaxial wafer is hardly subject to the influence of the auto doping phenomenon.
