Title: Optical vapor growth method
Inventor: HAMANO KUNIYUKI
IPC: H01L21/263
Filed: 1982-11-02
Abstract: PURPOSE:To increase the growth rate of a film by previously exciting a sensitizer containing one part of a reactive gas or one part of the reactive gas and mercury by ultraviolet beams before it is introduced to a reaction furnace, mixing the sensitizer with another gas in the reaction furnace and irradiating ultraviolet beams again at a stage where a reaction is generated. CONSTITUTION:The reactive gas A is mixed with a gas C as the sensitizer first, and enters in a spare exciting chamber 101 made of quartz, and the reactive gas A and the sensitizer C are brought to an exciting state by light sources 102. The excited gas A and the sensitizer C are introduced into the reaction furnace 103 made of quartz, mixed with a reactive gas B, irradiated by light sources 107 on a substrate 106 placed on a susceptor 105, a temperature thereof is changed by infrared ray lamps 104, and excited again. The growth rate of the film to the substrate 106 is increased remarkably because the reactive gas A and the sensitizer C contain a large amount of excited active seeds at a stage where they are irradiated by the light sources 107 and the reactive gas B is also excited.

Abstract: PURPOSE:To detect vignetting state in accordance with a real condition and to reduce its bad influence by detecting the vignetting state generated due to various undifined factors by using the output of an image sensor array to which various factors are superposed. CONSTITUTION:If the vignetting state is generated, a detecting means 50 sends an output indicating the generation of an unsuitable state to a detected state control means 60. The control means 60 compares the output with a threshold level, and when judges the output exceeds the limit, sends a switching control signal to switching means 33a, 33b. An autofocusing control means 70 switches a lens driving control mode on the basis of the control signal. The detecting means judges the existence of the vignetting state, and when the control means 60 outputs a control signal indicating the restoration of suitable states, the suitable lens driving control mode is restored on the basis of said output. Thus, the vignetting state can be detected and its bad influence can be reduced, so that highly accurate focus detection can be attained.
