IPC: C23C16/04
Filed: 1991-11-20
Abstract: PURPOSE:To prevent formation of unwanted metal film on a semiconductor substrate. CONSTITUTION:Before placing a semiconductor substrate on a susceptor 2, plasma 13 of a gas including chlorine is generated within a reaction chamber 6. The free bond of Si remaining at the surface of susceptor 2 is bound with chlorine.

Abstract: PURPOSE:To obtain a high speed flow of low static pressure averaged in an impeller outlet by providing an ultrasonic nozzle in an outlet of a fluid passage and in its inlet a throttle and forming a low speed path between the nozzle and the throttle, in the fluid passage between an impeller and a blade. CONSTITUTION:A fluid passage 21 between blades 13 and 13 of an impeller, rotated with a rotary shaft 6 serving as the center in a casing, provides an ultrasonic nozzle 18 in an outlet and a throttle 20 in an impeller inlet 19 and forms a low speed path (passage of slow flow speed) between the nozzle 18 and the inlet 19. Thus decreasing friction of fluid in the impeller and obtaining in the outlet a high speed flow increasing fluid kinetic energy in the outlet, a degree of reaction from the fluid is decreased by reducing a static pressure in the outlet. While by slowing a relative speed of the fluid in the low speed path 21, an inlet pressure of each nozzle 18 can be averaged. Thus in general, a high efficient ultrasonic centrifugal compressor of large compression ratio can be realized.
