摘要 |
<p>The present invention provides: an epitaxial film forming method capable of fabricating a +c-polarity epitaxial film made of a Group III nitride semiconductor by sputtering; and a vacuum processing apparatus suitable for this epitaxial film forming method. In one embodiment of the present invention, a Group III nitride semiconductor thin film is epitaxially grown by sputtering on anα-Al2O3 substrate heated to a desired temperature by using a heater. First, theα-Al2O3 substrate is disposed on a substrate holder including the heater in such a way that theα-Al2O3 substrate is disposed away from the heater by a predetermined distance. Then, an epitaxial film of a Group III nitride semiconductor thin film is formed on theα-Al2O3 substrate in the state where theα-Al2O3 substrate is disposed away from the heater by the predetermined distance.</p> |
