Abstract

Epitaxial layers are formed by introducing a reaction gas mixture into a reaction vessel in which semiconductor substrates are located, under a pressure of not higher than 1333 Pa (10 Torr), and heating said semiconductor substrates by high frequency induction power so that layers grow epitaxially on said semiconductor substrates. The frequency f of high frequency power is not higher than 50 kHz, and the pressure P in said reaction vessel is maintained in the following range ##STR1## wherein, P is the pressure in units of Pa or Torr in the reaction vessel and f is the frequency in kHz of said high frequency power.
