Abstract

PURPOSE:To decrease the nonuniformity of a GaAs compd. semiconductor single crystal by cooling the single crystal at a specific temp. gradient in a specific temp. range at the time of subjecting said single crystal to a heat treatment. CONSTITUTION:The GaAs compd. semiconductor single crystal produced by a liquid sealing Czochralski method is cooled in such a manner that the temp. gradient in at least the 800-900 deg.C temp. range attains <=0.8 deg.C per minute in the cooling process thereof at the time of subjecting the above-mentioned single crystal to the heat treatment in order to decrease the nonuniformity thereof. The crystal having the substrate characteristics uniform within the crystals and between the crystals is thereby obtd.
