- 化合物半導体単結晶の製造方法であって、
底部に種結晶の収納部を有する窒化ホウ素坩堝の少なくとも原料融液の接する内面に酸化ホウ素膜を形成し、
前記坩堝の底部の前記収納部内に前記種結晶を装填して、その坩堝の底部に酸化ホウ素下敷を配置し、
その酸化ホウ素下敷上に化合物半導体原料ブロックを配置し、この際に前記酸化ホウ素膜と前記原料ブロックとの間に互いの接触を防止する所定の小さな隙間を設け、
前記酸化ホウ素下敷を溶融させて、この酸化ホウ素融液によって前記所定の小さな隙間を満たし、
この状態で前記化合物半導体原料ブロックおよび前記種結晶の上部の一部を溶融させ、
その後に、前記種結晶からの一方向凝固によって化合物半導体単結晶を成長させることを特徴とする化合物半導体単結晶の製造方法。
