| 摘要 |
A method of manufacturing a semiconductor device by the use of a Group II-VI compound semiconductor crystal prepared by liquid growth method using a temperature difference technique under controlled vapor pressure of the crystal-constituting Group VI element. Thus, the concentration of vacancies and other defects acting as donor is reduced as compared with the concentration of the p type impurity to be introduced. This invention is suitable for producing light-emitting diodes emitting a light of short-wave lengths.
