Abstract: PURPOSE:To form uniformly a channel layer having a low source resistance by a method wherein a plurality of times of ion-implantation processes are provided, the surface of a semiconductor substrate is etched away in a process among the ion-implantation processes and a concentration on the side of the substrate surface is prevented from being reduced. CONSTITUTION:A cleaning of a semiconductor GaAs substrate 1 is performed and an impurity is removed. Thereafter, Si ions are accelerated by a low accelerating voltage and are ion-implanted to form an n'-type layer 2. Then, the surface of the substrate 1 is etched away by a necessary amount with an etching liquid and impurity ions, such as Si ions, are ion-implanted in the etched substrate 1. Moreover, a silicon oxide film is adhered on the surface of the substrate 1 in a proper thickness by a CVD method and an activation annealing is performed in a hydrogen-containing atmosphere to remove the silicon oxide film. Thereby, the implanted ions are activated and an n-type channel layer 3 is formed. A concentration reducing layer on the side of the substrate surface after the ion-implantation is etched away and the n-type channel layer 3 having a low source resistance can be formed uniformly.
