IPC: H01L21/322
Filed: 1986-03-28
Abstract: PURPOSE:To introduce lattice defect without leaving contamination sources, by ejecting ice particles, and making them crash against the back surface of a semiconductor wafer. CONSTITUTION:From a supplying source 2, liguid N2 3 is introduced into a vessel 1, which is filled up to about half depth, and N2 gas with a specified flow rate is blown via a heat exchanger 5 to generate waves of several mm on the liguid surface. Pure water with a specified pressure and a flow rate is sprayed together with N2 gas to form ice particles 8, which are conveyed to a hopper 10. With the N2 gas having a specified high pressure and a flow rate, the ice paricles are ejected at a rate of 0.3 l/min, and made Crash against the back surface of a wafer to introduce lattice defect. As the fine ice particles are used, particles or cut-off powder acting afterwards as contamination sources do not remain. When ice particles made of a water wherein CO2 gas is contained in super pure water and the specific resistance is equal to or lower than 1MOMEGA.cm are used, the possibility of attraction of contamination substances due to electrostatic charge at the time of ejection impact can be avoided.

Abstract: PURPOSE: To improve the operationability of an engine, by controlling an EGR rate in accordance with a loading condition when the engine is in operation.  
     CONSTITUTION: When an engine is operated in a specific condition (at its cold state or low speed with a large amount of load and high speed with a small amount of load), a controller 29 inducts a static pressure of a line pressure P between an orifice 8 in an EGR line 7 and an EGR control valve 9 as a power actuating source into a pressure chamber 20 of a negative pressure regulator 18 through lines 24, 26. In this way, pressure in the pressure chamber 20 is relatively lowered to push down a diaphragm 19 by a spring 23 and dilute a negative pressure to a negative pressure chamber 13. While at the time of normal operation of the engine other than the above described specific condition, a dynamic pressure of the line pressure P is inducted as the actuating power source into the pressure chamber 20 through lines 25, 26 to decrease the level of dilution of the negative pressure to the negative pressure chamber 13 and enlarge the opening degree of a valve unit 12 of the EGR control valve 9.
