Title: Detection of defect for transparent body
Inventor: YAMAZAKI CHIYUUZABUROU
IPC: G01N21/88
Filed: 1980-09-09
Abstract: PURPOSE:To absorb the light scattered by the defect near the rear surface of a transparent body during passing of the transparent body and prevent the defect from being detected near the rear surface by using an incident ray of the absorption wavelength region of the transparent body. CONSTITUTION:When an incident ray is the ray of the absorption wavelength region of a transparent body 1 to be detected of defects, the incident ray is gradually absorbed and weakened by the body 1 while it is passing through the body 1. Hence, the ray projected to a defect 4 existing near (b) the rear surface of the body 1 is gradually absorbed and weakened by the body 1 while it is passing through the transparent body before it is projected, and further the scattered and reflected abnormal light by this defect 4 is also absorbed while it is passing through the transparent body; therefore at the time when the reflected abnormal light toward a detector 3 emerges from the body 1, it is substantially absorbed by the body 1 and is difficult to be detected by the detector 3.

Title: Annealing process of gaas wafer
Inventor: ITO KAZUHIKO
IPC: C30B33/02
Filed: 1985-06-10
Abstract: PURPOSE:To obtain sufficient effect for preventing wafer surface from being roughened with less flow rate of AsH3 by using solid GaAs placed at upstream side of a GaAs wafer as catalyst for decomposing AsH3. CONSTITUTION:Solid GaAs 5 mounted on a supporting base 6 is placed at the upstream side of a GaAs wafer 1 which is set on a wafer supporting base 2 in a reaction tube 3. Said GaAs wafer 1 is annealed in the atmosphere of gas stream contg. a constitutional element of the wafer 1 or a compd. of the constitution element (e.g. AsH3). Thermal decomposition of gaseous AsH3 intro duced into the reaction tube 3 is accelerated by the solid GaAs 5, so higher As pressure than conventional process exerts on the surface of the GaAs wafer 1. Therefore, elimination of As atoms from the surface of the wafer 1 is retarded. Thus, roughening of the wafer surface and deterioration of characteristics of an ion implanted layer are prevented.

A means F calculates a lower limit level of a speed under an air-fuel ratio feedback control in such a manner that a judgment level becomes high when the deceleration degree detected by the means E is high. In comparison of the speed detected by the means D with the judgment level calculated by the means F, a means G prohibits the air-fuel ratio feedback by the means C.
