Abstract
PURPOSE:To obtain a Cadmium telluride (CdTe) based crystal of high purity without contamination with boron, by hermetically sealing a growth chamber with liquid B2O3 so as to prevent a gas in the growth vessel provided in a high-pressure chamber from leaking into the high-pressure chamber and keeping the temperature of the above-mentioned B2O3 within a given temperature range. CONSTITUTION:A crucible 1, containing CdTe melt 2 and rotatably supported by a crucible shaft 3 is placed in the interior of a growth chamber 4. A through- hole for passing a pulling up shaft 6 for pulling up a CdTe crystal 5 from the melt 2 is formed in the upper part of the chamber 4 and a receiving part 7 is formed on the through-hole. Liquid B2O3 placed in the receiving part 7 is used to prevent vapor in the interior of the chamber 4 from leaking to a high-pressure chamber 10. In this case, temperature of the above-mentioned liquid B2O3 is kept at 730-1,080 deg.C. Contamination with B due to the B2O3 vapor in the CdTe based crystal is prevented according to the method of this invention and the aimed CdTe based crystal without contamination with the B can be grown.
