Abstract

PURPOSE: To increase yield rate during the growth of the epitaxial layer and prevent the reduction of characteristics as a high-frequency element by making it possible to use the epitaxial growing crystal layer which has comparatively higher positive hole density as a buffer layer.
CONSTITUTION: 2 Layers of a p-type layer 2A and a n--type layer 2B which constitute a buffer layer 2 are formed on a half insulating substrate 1 composed of mainly GaAs, and the value of the positive hole density for the p-type layer 2A is set lower than the fixed one so that the comparatively easy doping condition may be obtained. After setting the value of the electron density of the n--type layer 2B lower than the fixed one, the p-type layer 2A and n--type layer 2B are successively formed according to the gaseous phase epitaxial growing method. Next after forming the n--layer 2B, the growth of the epitaxial is further continued by supplying a dopant such as Sn, Te, S, Se, etc. so as to form an active layer 3 on the n--type layer 2B. Thus the yield rate in the growth of the epitaxial layer is increase, and the characteristics of a semiconductor device is improved.
