发明名称 Method for manufacturing nitride semiconductor element
摘要 A first nitride semiconductor layer laminating step includes a first step and a second step. In the first step, an entire upper surface of the sapphire substrate is coated with a first nitride semiconductor layer, while supplying oxygen. In the second step, crystals of the first nitride semiconductor layer are grown by supplying oxygen at a smaller flow rate than that of oxygen supplied in the first step, or without supplying the oxygen.

主权项 1. A method for manufacturing a nitride semiconductor element comprising: a step of laminating a first nitride semiconductor layer of single crystals of AlxGa1-xN (0.5<X≦1) on an upper surface of a sapphire substrate by a metal organic chemical vapor deposition; and a step of laminating a second nitride semiconductor layer on the first nitride semiconductor layer, wherein the step of laminating the first nitride semiconductor layer includes: a first step of coating an entire upper surface of the sapphire substrate with an under nitride semiconductor layer while supplying oxygen, and a second step of growing an upper nitride semiconductor layer while supplying oxygen at a smaller flow rate than that of oxygen supplied in the first step, or without supplying oxygen.
