Title: Apparatus for growing molecular-beam-epitaxial-crystal
Inventor: FUJII TOSHIO
IPC: H01L21/203
Filed: 1984-10-13
Abstract: PURPOSE:To improve the yield rate of the area of a growing film, by providing a part, whose thickness is thinner than that of a substrate holding area, around the substrate holding area of a holding block, and expanding the area, wherein temperature distribution is relatively uniform. CONSTITUTION:A V-shaped groove 5 is added in a holding block 1a so that a part, whose thickness is thinner, is provided around the substrate holding area of the holding block 1a. Owing to the thin part, heat, which is conducted toward the outer part from the peripheral part of the substrate holding area in the holding block 1a, is decreased. The temperature distribution of the substrate holding surface 2 is shown by a solid line (b). Namely, in comparison with a conventional analysis (a), the temperature at the peripheral part is largely decreased even if the temperature at the central part is the same as the conventional device. Thus the area, whose temperature distribution is relatively uniform, becomes larger than that in the conventional device.

Abstract: PROBLEM TO BE SOLVED: To enable a taper angle to be measured without contact highly accurately, rapidly and automatically by placing an image pickup means above a center axis of a light projection means and catching a reflection beam of a disk beam which comes against the conic internal face of an object to be measured. SOLUTION: Semiconductor laser light is emitted from a laser emission head 3, and collimated parallel light is incident to a glass rod lens (optic fiber) 2. A conic beam emitted from the other end of the optic fiber 2 is converted into a disk beam when shed to a conic mirror 1 and shed to a conic orbit of an outer wheel 7 of a conic roller bearing, resulting in reflection light incident to a CCD camera 8. An orbit face of the outer wheel 7 of the conic roller bearing is a metallic gloss having predetermined roughness, wherein the reflection light becomes scattering light having a certain reflection pattern. Light among this scattering light which has passed through a camera lens is focused inside the CCD camera to be formed as an image.  An image processor 9 calculates a gradient angle of a conic face from a center axis from a vertical movement amount of an object to be measured and an amount of change in a diameter of the disk beam.
