Patent EP-0266227-A2 (EP)
Inventor: YOSHIDA SEIKOH C O FURUKAWA-RY
IPC: C30B11/00
Filed: 1987-11-02
Abstract: A method and an apparatus for growing a crystal of a compound semiconductor, in which a heater (16), used to heat a boat (13) for growing the semiconductor crystal, is disposed around an ampule (11) containing the boat (13), and a melt of the compound semiconductor (15), which is prepared in the boat, is frozen gradually at a predetermined temperature gradient including the freezing point of the melt, from a crystal growth starting end of the boat to a crystal growth terminating end thereof, whereby a single crystal or a polycrystal is grown. At the start of crystal growth, a crystalline nucleus is formed by periodically changing the temperature of the crystal growth starting end of the boat, in descending and ascending modes, within a temperature range lower than the melting point of the compound semiconductor, after once lowering the temperature of the starting end to a level lower than the melting point by means of a heater block opposed to the starting end. The crystal is grown around the crystalline nucleus formed in this manner. Preferably, the temperature change at the crystal growth starting end is slower in the descending mode than in the ascending mode. The method of the invention may be applied without regard to the use of a seed crystal.
