Abstract

PURPOSE: To grow the semiconductor single crystal of low impurity concentration with a good reproducibility, by carrying out meltback of base board and growing the crystal in liquid phase by the impurity in the base board after contacting single crystal base board containing a fixed impurity, with thin layer solution and carrying out baking in inactive or reducing atmosphere.
CONSTITUTION: The single crystal base board 17 containing a fixed quantity of donor impurity, is inserted in the concave part 18 of the slider 15 and the liquid phase growth solution 27 is packed in thin layer at the opening. H2 gas is flowed in the reaction furnace 10 from the gas introducing tube 12 and the board 17 and the solution 27 are heated by the main heat source. Both are contacted moving the slider 15 when the temperature is reached at 300W900°C and baking is carried out and then, meltabck of the board 17 is carried out. The donor impurity, for example, S of this portion is completely discharged out of the solution 27 together with sulfides in the solution 27. Next, temperature is risen to the crystal growth beginning temperature. By the above heat treatment, a fixed donor concentration is obtained in the solution 27 by S of the part carried out meltback. In such a condition, n-formed layer is grown on the board 17 by cooling.
