Methods of manufacturing compound semiconductor crystals and apparatus for the same |
摘要 |
A method of manufacturing compound semiconductor crystals, comprising the steps of, providing a compound semiconductor melt in a crucible, said melt having a composition ratio which deviates from stoichiometry, pulling a compound semiconductor crystal from said crucible by using a seed crystal, and during the pulling step, adding to the melt a constitutional element of said compound semiconductor melt which is present in less than a stoichiometric amount, the element being added in a quantity sufficient to maintain said composition ratio of the first step. An apparatus for manufacturing compound semiconductor crystals is also provided.
