Abstract:
1. An apparatus for manufacturing a GaN substrate, comprising: a chamber for loading a substrate therein; a heating means heating the chamber; a Ga boat installed inside the chamber to receive a Ga molecule producing material; an injection pipe injecting a nitrogen molecule producing gas in the chamber, the nitrogen molecule producing gas reacting chemically on the Ga molecule producing material to form a GaN layer on the substrate; a transparent window at a circumference of the chamber to apply a laser beam to the substrate; an auxiliary chamber at a lateral side of the chamber to keep the substrate in store temporarily; a gate valve closing/opening a path between the chamber and the auxiliary chamber; and a bellows at a lateral side of the auxiliary chamber to maintain a vacuum state inside the auxiliary chamber.
