Title: Method for growing compound semiconductor crystal
Inventor: SUGIYAMA IWAO
IPC: H01L21/365
Filed: 1988-11-22
Abstract: PURPOSE:To fill the vacant lattices of a crystal with mercury by heat treatment in a short time and to make it possible to introduce mercury into the vacancies at a uniform concentration along the direction of the thickness of a crystal layer by heating a compound semiconductor substrate which is provided in a reaction tube, supplying the mercury and an epitaxially growing gas other than the mercury on the substrate, growing the epitaxial crystal, supplying only the mercury to the substrate, and heat- treating the crystal. CONSTITUTION:A substrate 3 is provided on a susceptor 2 in a reaction tube 1. Hydrogen gas as a carrier gas and the gases of dimethyl cadmium, diethyl tellurium and mercury which are supported by the hydrogen gas are introduced into the reaction tube 1 through a gas introducing pipe 19. An epitaxial crystal 31 of Hg1-xCdxTe is formed on the substrate. A valve 22 is opened. The hydrogen gas and the mercury gas are introduced into the reaction tube 1 under the state wherein the partial pressure of the mercury is made higher than that in epitaxial growing. With the substrate 3 being heated, heat treatment for filling the vacancies of the crystal 31 is performed. Thus the crystal 31 is transformed into an N-type epitaxial crystal 32. When this operation is repeated many times, the epitaxial crystal layer of Hg1-xCdxTe which is transformed into the N type having the specified thickness is obtained.
