Patent TW-550629-B (TW)
Title: Heat treatment system and method
Inventor: ASANO TAKANOBU
IPC: C30B33/00
Filed: 2001-05-31
Granted: 2003-09-01
Abstract: When an oxidation process for semiconductor wafers is carried out by a batch type furnace, the uniformity of the thickness of a film is intended to be improved so as to be capable of carrying out a low temperature process. In a system for feeding a mixed gas of hydrogen gas and water vapor into a reaction vessel to carry out a so-called wet oxidation, a ventilation resistance material is provided in an outside passage of a double-pipe passage for heating gas in an external combustion system, and a mixed gas of hydrogen gas and hydrogen chloride gas is passed through the ventilation resistance material to be heated to a process temperature or higher by means of the heater of the combustion system to previously produce a very small amount of water vapor to carry out a dry oxidation. When dinitrogen oxide gas is used for producing a nitrogen containing silicon oxide film, dinitrogen oxide gas is passed through the outside passage to be previously activated. In addition, a process gas is preheated by a heating part, which is provided outside of a process chamber, to lower a process temperature while ensuring the uniformity of a process. N2O gas and SiH2Cl2 gas are fed into a reaction tube 102, which has been pressure-reduced to a predetermined degree of vacuum, to deposit a thin film on the surface of a wafer at a predetermined process temperature. At this time, a heating chamber 151 provided in a N2O gas feed passage is heated by a heater element 153, and N2O gas is passed through the heating chamber 151 to be preheated to be fed into the reaction tube 102. In addition, an orifice 106 is formed in the N2O gas feed passage between the heating chamber 151 and the reaction tube 102. Thus, even in a low pressure process, the pressure in the heating chamber 151 is higher than the pressure in the reaction tube 102 due to pressure loss at the orifice 106, so that it is possible to efficiently preheat the process gas in the heating chamber 151 to lower the process temperature.

Title: Method for manufacturing piezoelectric element
Inventor: SUGIZONO ATSUYUKI
IPC: H01L41/313
Filed: 2001-06-20
Granted: 2003-01-11
Abstract: The present invention provides a method for manufacturing a piezoelectric element in which a substrate of piezoelectric material having high planarity and parallelism can be formed without having any adverse effect on the resonance characteristics thereof. The method for manufacturing a piezoelectric element comprises: a step for making trenches on the surface of a reinforcing plate, and a step for bonding the reinforcing plate to a substrate formed of piezoelectric material by introducing an adhesive having fluidity into the trenches of the reinforcing plate. Thus, the reinforcing plate can be bonded to the substrate formed by the piezoelectric material with predetermined strength. Also, by polishing the substrate formed by the piezoelectric material and which is bonded to said reinforcing plate, a substrate of piezoelectric material having high planarity and parallelism can be formed. Furthermore, since the adhesive layer can be dissolved simply by organic solvent, etc., the reinforcing plate can be peeled off in the state without applying any physical strength on the substrate formed of the piezoelectric material. Therefore, the resonance characteristics of the substrate formed of the piezoelectric material can be effectively kept.

Title: Method for pre-cleaning residual polymer
Inventor: WU YAN-PING
IPC: H01L21/3065
Filed: 2001-07-24
Granted: 2003-04-11
Abstract: A kind of method for pre-cleaning residual polymer is disclosed in the present invention. After using the reactive gas containing fluorocarbon to perform the etching process, the mixing gas that is mixed with the specific gas is added. The plasma generated by the mixing gas is then used to conduct the pre-cleaning process of the residual polymer. The specific mixed-gas can be selected from one of the following mixed gas, for example the mixed gas of oxygen and nitrogen, the mixed gas of hydrogen and argon, the mixed gas of argon and nitrogen, or the mixed gas of oxygen and argon. Because the plasma generated by the mixed gas is capable of softening the residual polymer, burning the residual polymer, and even stripping the hardened residual polymer, the etched residual polymer can be completely removed in the following cleaning process and the processing time can be decreased.

In view of the above, the present invention provides a river water flood prevention and rescue electricity supplying system that retrieves water flow energy from river flood and transforms the energy into high pressurized pneumatic energy which is transmitted to an air storage tank provided at the river bank, which is then transmitted to an appropriate region. The high pressurized pneumatic energy is then converted into mechanical energy for driving generators thereby supplying rescue electricity power. The system operation is environmental friendly because it doe not require electricity or fuel energy. The mechanism allowing for the system operation is not affected by surrounding environment such that the system is reliable and meets the needs for rescue electricity so as to protect lives and properties of residents.
