| description | PROBLEM TO BE SOLVED: To provide a vapor growth apparatus of a group III nitride semiconductor which can prevent a crack of a substrate even in a case of vapor growth of a substrate with a diameter of three inches or larger. SOLUTION: The vapor growth apparatus of a face down type group III nitride semiconductor includes a susceptor for holding the substrate with a down-turned crystal growth surface, an opposite face of the susceptor, a heater for heating the substrate, a material gas introducing part arranged in a center part of the susceptor, a reaction furnace formed of a gap between the susceptor and the opposite face of the susceptor, and a reaction gas discharge part arranged on an outer circumference side of the susceptor. The susceptor 2 includes four or more claws 10 for one substrate holder 8. COPYRIGHT: (C)2010,JPO&INPIT |
