Patent ID: 10283671

Abstract:
Provided is a method of producing a III nitride semiconductor light-emitting device having an n-type semiconductor layer, a light emitting layer, a barrier layer, and a p-type semiconductor layer. The p-type semiconductor layer is formed by forming an electron blocking layer on the light emitting layer; supplying a carrier gas containing nitrogen to a surface of the electron blocking layer; and forming a second p-type contact layer made of AlyGa1-yN on the electron blocking layer after the nitrogen carrier gas supply step. The second p-type contact formation step is performed using a carrier gas containing hydrogen. Source gases of Al and Ga are supplied to form a first p-type contact layer made of AlxGa1-xN with a thickness of more than 0 nm and 30 nm or less directly on the electron blocking layer and directly under the second p-type contact layer.
