Title: Epitaxial growth device
Inventor: TSUKUYAMA YOICHI
IPC: H01L21/205
Filed: 1988-05-10
Abstract: PURPOSE:To seek to restrain the generation of slipping dislocation, and dispersion of resistivity and thickness of silicon epitaxial layer, by providing a recessed pocket equal to or larger than a semiconductor substrate 1, whose bottom face is compound shape of spherical surface and flat surface, at the main surface of a susceptor. CONSTITUTION:It is constituted such that a recessed pocket having the size equal to or larger than a semiconductor substrate 1, whose bottom face is a compound shape of spherical surface and flat surface, is provided at the main surface of a susceptor 2. When the semiconductor substrate 1 is heated by the use of this susceptor 2, a warp arises in the semiconductor substrate 1 by the temperature difference between the obverse and the reverse of the semiconductor substrate 1. But the pocket applied to the susceptor 2 is so made that the periphery and the center of the semiconductor substrate 1 may contact with the susceptor when the semiconductor substrate 1 is warped, so the temperature inside the surface of the semiconductor substrate 1 becomes uniform, and the warp caused by the temperature inside said substrate surface is softened. Hereby, it can restrain generation of slip dislocation of the semiconductor substrate 1, dispersion in resistivity and thickness of silicon epitaxial layer.
