Abstract:
Methods of fabricating transistor in which a first Group III nitride layer is formed on a substrate in a reactor, and a second Group III nitride layer is formed on the first Group III nitride layer. An insulating layer such as, for example, a silicon nitride layer is formed on the second Group III nitride layer in-situ in the reactor. The substrate including the first Group III nitride layer, the second group III nitride layer and the silicon nitride layer is removed from the reactor, and the silicon nitride layer is patterned to form a first contact hole that exposes a first contact region of the second Group III nitride layer. A metal contact is formed on the first contact region of the second Group III nitride layer.
