Title: Molecular beam epitaxial growth method
Inventor: MASHITA MASAO
IPC: H01L21/20
Filed: 1984-12-20
Abstract: PURPOSE:To easily dope the N-type impurity in high concentration to a III-V compound even under a low vaporization source temperature by using both P and As or mixture of any one of them and Si as the N-type dopant and an allow as the vaporization source material. CONSTITUTION:The vapor pressure of Si increases by alloying P and As. For example, an alloy of Si and As is used as the vaporization source. If As exceeds 50atom% as the composition range, a melting point lowers and it is not desir able. The alloy is not always used as the vaporization source and it is also possible that Si and As are supplied to a crucible and these are wetted to obtain an alloy of them. When it is required to dope the N-type impurity in high con centration to the GaAs III-V compound semiconductor, temperature of vaporiza tion source may be comparatively low by using an alloy of Si and As as the vaporization source. Thereby, deterioration of the material which forms vaporiza tion source can be suppressed and life span of vaporization source can be extended.

CONSTITUTION:A cryostatic refrigeration equipment 500 executes necessary cryostatic cooling by supplying a cryostatic cooling by supplying a cryostatic cooling machine 23 with a refrigerant body pressurized by a compressor 11. An oil separator 12C separates a mixed fluid 11a pressurized by the compressor 11 into oil 12b and the refrigerant body 12a. The separated fluids are cooled down by a refrigerant body heat exchanger 12D and an oil heat exchanger 12E respectively and then returned into the compressor part 11. Based on a detection signal 51a, a controller 53 controls a flow adjusting valve 52 so that the quantity of the oil 12b to be returned into the compressor 11 be made small when the oil 12b separated by the oil separator 12C is much and that the quantity of the oil to be returned is made large when the separated oil 12b is little. Since the excess and deficiency of the separated oil 12b are eliminated, invasion of the oil into the refrigerant body heat exchanger 12D and lowering of an operating efficiency due to the refrigerant body's bypassing the oil exchanger 12F are eliminated.
