Title: Silicon wafer and cleaning thereof
Inventor: MORITA ETSURO
IPC: H01L21/306
Filed: 1995-11-08
Abstract: PROBLEM TO BE SOLVED: To provide a silicon wafer with a natural oxide film wherein the concentration of boron on the surface is reduced, and to exclude a deleterious effect in a device process, and to manufacture a silicon wafer with a natural oxide film wherein the concentration of boron is reduced. SOLUTION: A silicon wafer is cleaned with a dilute fluoric acid solution, and is then soaked in pure water including three to ten ppm of ozone. The silicon wafer is preferably soaked in water including eight ppm of ozone (made from O2 generated by the electrolysis of ultrapure water) for 15 seconds. As a result, a natural oxide film of 5 to 7 Å depth is formed on the surface to obtain the silicon wafer wherein the concentration of boron in the natural oxide film is controlled to be 10<10> atoms/cm<2> or less. Reduction in the concentration of boron extremely decreases a deleterious effect in a device process. At the same time, metallic contamination on the wafer surface can be reduced. The concentration of Al, Fe, Cu, or others can be reduced to less than 10<9> atoms/cm<2> . Also two wafers can be excellently bonded together. On resistance of VDMOS can be also decreased.

Title: Rotor for gas turbine engine
Inventor: DEBITSUDO KAAPENTAA JIYAAMON
IPC: C03C14/00
Filed: 1988-12-15
Abstract: PURPOSE: To increase the elastic coefficient of a turbine rotor with the increasing radial outward distance from the inner circumference thereof by increasing the volume fraction of a silicon carbide monofilament fiber reinforcement with the distance. CONSTITUTION: A turbine rotor is formed by a glass matrix or a glass ceramic matrix reinforced with silicon carbide yarn fiber reinforcement and with silicon carbide monofilament fiber reinforcement. The volume fraction of the monofilament fiber reinforcement of each composite ply number is increased with the increasing radial outward distance from the inner circumference of the turbine rotor. The composite plies are arranged integrally so as to increase the elastic coefficient gradually from the inner circumference to the outer circumference along with the increase in volume fraction. Thus, it is possible to avoid stress concentration on the internal wall on which the largest stress is applied by allowing the stress applied to the internal wall to escape to the external wall of a greater ply number by the high internal pressure acting uniformly in the radial direction of the rotor.

IPC: F27B3/22
Filed: 1995-10-30
Abstract: PROBLEM TO BE SOLVED: To keep a molten metal temp. to a fixed value by calculating enriching quantity of necessary pure oxygen based on molten metal tapping temp., controlling the oxygen concn. in a specific range and supplying to a tuyere of a furnace body. SOLUTION: An air flow rate control valve 7 and an oxygen flow rate control valve 7 are controlled with a program controller 10 to adjust the air quantity and the oxygen quantity into a vertical type melting furnace 1. The molten metal in the melting furnace 1 is tapped from a siphon part 16. The molten metal tapping temp. is continuously measured at the siphon part 16 with a molten metal temp. measuring instrument 17 and transported to the controller 10. A theoretical oxygen quantity needed to combustion is calculated in the range of 1-20% of the enriching rate and the opening degree of the oxygen flow rate control valve 12 is adjusted through the controller 10 to supply the oxygen from an oxygen tank 11. The oxygen is mixed with the air and supplied into the melting furnace 1 from the tuyere 2.  Since the optimized oxygen enriched quantity is supplied, the operational cost can be reduced. Since the response time to the oxygen enriched quantity is quickened such as five min., the quantity control is facilitated. Further, since the stable melting at high temp. can be executed, component control is facilitated.
