Title: High-voltage MOS transistor for protection circuit
Inventor: CHAO MEI-LIN
IPC: H01L23/60
Filed: 1999-11-11
Granted: 2001-04-11
Abstract: A high-voltage MOS transistor for ESD protection circuits is provided. The protection circuit is produced on a semiconductor chip. The semiconductor chip comprises a substrate, an active region with a doped region and a field oxide layer composed of silicon dioxide and formed at the periphery of the active region. The inventive high voltage MOS transistor comprises a gate formed by stacking a doped polysilicon layer and a gate oxide up and down; a source/drain having double diffusing drain structure configured in the doped region and located at both sides of the gate; and an insulation layer composed of silicon dioxide and located between the gate and the source, and between the gate and the drain. There is no drift region formed under the insulation layer, and thus the threshold voltage between the source and the drain can be increased. The input of the protection circuit is electrically connected to the source, and the drain and gate are electrically connected to a power source. When the input voltage exceeds the threshold voltage between the source and the drain, the source and drain will be conducted by the doped region in the active region to eliminate the excess voltage inputted from the input port.

IPC: H01J15/00
Filed: 1999-12-01
Granted: 2001-05-28
Abstract: The present invention is an electrode layout structure and method of plasma display panel, mainly by disposing respectively a plurality of power supplying connection points at two terminals of X electrode and Y electrode which are mutually parallel and space apart inside the front substrate of the plasma display panel, so that the power supplying connection points which cannot operate normally on the open position side can be jumpingly connected to the power supplying connection points on the other side when anyone position of the electrode is open due to manufacturing defect of the electrode in the manufacturing process, thus the electrode which cannot be operated normally can still receive the power to operate normally and discharges, thereby the effect of the open circuit to the display quality of the plasma display panel is greatly reduced, the yield rate of manufacturing the plasma display panel is effectively increased, and the manufacturing cost is greatly reduced.

Title: Method and apparatus for digitalized multiple impulses fluid flow measuring system
Inventor: LEE CHANG-CHI
IPC: G01F1/68
Filed: 2000-05-08
Granted: 2002-11-21
Abstract: A device and method for fluid flow rate measuring have been designed providing high resolution and very wide range measurement. This invention includes a flow channel with constant cross-sectional area, a heating coil wired on the flow channel, at lease two heat sensors with constant space alone the flow channel, and a control circuit. The fluid carries the thermal impulse while passing through the heating coil, and then downstream to heat sensors. The transient time between the two sensors can be recorded and therefore the volume flow rate of the fluid is calculated. This invention employs a design of multiple thermal impulses with different frequencies. High frequency impulse signal is valid for high flow rate and low frequency signal is effective for low flow rate. By changing the frequency from the control circuit, we can easily change the measuring range. Therefore, this invention is a precise and very wide range measuring method.

Title: Method of temperature-calibrating heat treating apparatus
Inventor: SUZUKI FUJIO
IPC: C30B25/10
Filed: 2000-08-31
Granted: 2002-02-21
Abstract: A second vertical heat treating apparatus is temperature-calibrated based on a heat treatment result obtained by a first vertical heat treating apparatus for reference. First, temperature measurement wafers is heated in the first apparatus to obtain set values of temperature controllers for a target value of temperature. Then, wafers are subjected to an oxidizing process in the first apparatus by using these set values to form an oxide film. The thickness of the oxide film is measured and recorded as a reference film thickness. Then, wafers are subjected to an oxidizing process in a second apparatus at temperatures near the target value to form an oxide film. The thickness of the oxide film is measured, and difference in thickness between the oxide film formed in the second apparatus and the reference film thickness is obtained. The oxidizing process in the second apparatus is repeated to obtain set values of temperature controllers for the second apparatus at the time when the difference in film thickness becomes zero. The second apparatus is temperature-calibrated on the basis of the set value thus obtained.

Title: Method for forming conducting bump on contact pad
Inventor: GUO WEN-JANG
IPC: H01L23/00
Filed: 2001-03-23
Granted: 2002-01-21
Abstract: The present invention relates a kind of method for manufacturing a bump. A stencil printing method is used in the invented method, in which the variation of positive pressure difference between solder paste and the wafer is used. After solder paste is squeezed downwards from the stencil mask, a much better contact property between the solder paste and the metal under the bump is obtained by combining the ultrasonic oscillation in the horizontal direction, and a smoother flow of solder paste flowing from the mask under the solder paste tank is obtained by combining the ultrasonic oscillation in the vertical direction. In addition, through the cooperation of moving the wafer downward, the solder paste bump can be made to grow up to a predetermined height. At last, solder paste is cut off by the combination of ultrasonic oscillation in horizontal, vertical directions of the stencil plate, and the adjustment of negative pressure difference between solder past tank and the wafer. Therefore, stability of quality can be assured as long as stable values for the pressure difference value and the moving downward speed of wafer are appropriately allocated.

Title: Power factor correcting method for lower standby power and its circuit apparatus
Inventor: DING GUO-TING
IPC: H02M7/02
Filed: 2001-05-25
Granted: 2003-03-21
Abstract: The invention proposes a front stage control method of switch-type power factor correction. Under the standby or low load condition, the method is featured with having extremely low power loss such that the input power also is very low. The invention is very suitable for use in the modern electronic apparatuses for having reduced influence on the environment. Under the standby or low load condition, most of the power loss for the switch mode power supply is the switch loss. Because the switching loss is proportional to the switching frequency of the switch implement, power loss of the standby state is decreased when the operation frequency of low load is reduced. The invention uses a specific switch timing control to achieve the purpose stated above.
