Abstract: PURPOSE:To obtain the apparatus for growing the film of uniform thickness and good crystallization in gas-phase by the low output of radiant ray by preventing the deposition of reaction products on a plate through which the radiant ray permeates without using air-cooling means by heating a substrate by radiation of ray. CONSTITUTION:The heat ray of a lamp 9 heats a table 8 and an Si substrate 7 to the predetermined temperature through a transparent glass plates 10 and 14. A proper quantity of H2 of room temperature is supplied 17 to be spouted from a hole 15 of the plate 14. At the same time, the reactive gas of H2 base which includes SiH2Cl2 and PH3 by proper concentrations is supplied 18 at room temperature and is introduced 19 into the center of reaction chamber. While the reactive gas mixed to the predetermined concentration is exhausted 20, an epitaxial film is formed on the substrate 7. A jet A of H2 compels a flow B of the reactive gas to flow in direction C and upward flow of the reactive gas caused by a natural convection also flows in direction C thereby preventing deposition of reaction products on the plates 14 and 10. An eddy flow at this time makes a temperature in the vicinity of the substrate uniform and makes a growing speed and film thickness uniform. Also, H2 is heated prelinarily by a wall 11, fixing member 16, heater block 12 and glass plate 10 and the temperature becomes higher than room temperature even after mixing so that a difference in temperature between the mixed gas and substrate can be made low enough by the low output of the lamp.

Title: Laser oscillator
Inventor: KARASAKI HIDEHIKO
IPC: B23K26/00
Filed: 1990-06-05
Abstract: PURPOSE:To relieve output power from its dependence on the voltage of the power source by detecting the voltage of AC power source and controlling switching frequency in conformity with the range of fluctuations in a reference signal. CONSTITUTION:When the AC voltage of a power source fluctuates, the fluctuations are detected by a voltage detector 21 and the detected data enters an error amplifier 22. On the other hand, the reference voltage of a reference voltage signal generation circuit 24 enters the error amplifier 22. The difference enters an output setting circuit 28 where the output setting circuit 28 controls the switching on time of a switching low voltage power source so as to unify the power and outputs the controlled power. A drive circuit 23 switches a switching device based on the switching time and the fixed switching frequency from a switching frequency setting circuit 29. It is, therefore, possible to unify the output power and hence stabilize laser output by detecting the voltage of the power source and controlling the switching on time, responding to the range of fluctuations in the reference signal in this manner.
