Abstract

PURPOSE: To facilitate the forming with ease a number of JFET for high voltage power thru the method wherein the process of forming semiconductor layers of high density on substrate, the process of forming semiconductor layers of low density on the foregoing layers and the process of introducing impurities of inverse conduction electrode selectively are repeated.
CONSTITUTION: N-type semiconductor layer 2 of high density to become drain of JFET is epitaxial grown on n-type semiconductor substrate 1, upon which n-type semiconductor layer 3 of low density to become channel is also epitaxial grown. Within the semiconductor layer 3, high density p-type impurity gates 4 of specific stripe form are selectively formed. On those gates, low density n-type semiconductor layers 5 are grown and are made as drain. The above procedures are repeated which construct JFET for high voltage power three dimentionally. In the procedures, semiconductor layers 5 may be left out.
