Title: Semiconductor substrate
Inventor: TANNO YUKINOBU
IPC: H01L21/205
Filed: 1982-05-04
Abstract: PURPOSE:To inhibit the generation of a slip in case of epitaxial growth, and to improve the yield of a device by introducing an element, an atomic radius thereof is smaller than atoms constituting a semiconductor substrate and which is electrically more inactive than them, to the back of the semiconductor substrate. CONSTITUTION:When the element, the atomic radius thereof is small and which is electrically inactive, is introduced to the back of the semiconductor substrate, the back side is normally subject to compressive stress and the upper side is convexed on the heating of epitaxial growth in the semiconductor substrate. The convex results in an excellent contact state of a susceptor and the semiconductor substrate, and relaxes the unevenness of the temperature of the semiconductor substrate. The selection of the electrically inert element is undesirable because an impurity is redistributed to the surface side from the back of the semiconductor substrate on epitaxial growth and the electrical characteristics of an epitaxial layer change, but such a thing is not generated in an inert element. When the quantity of a dose, in which carbon and nitrogen are injected to the back of the substrate, and s slip generation rate seen after epitaxial growth are plotted, the more ions are injected at high concentration, the less the slip generation rate reduces.
