Abstract:
A method of vapor-phase growth of a nitride semiconductor comprising the steps of:supplying a first amount of a source material to a base body of the nitride semiconductor during a first time period; selectively growing a first portion of a nitride semiconductor layer on the base body during the first time period wherein the first portion is grown over a first area along a plane that is substantially parallel to a principle plane of the base body; supplying a second amount of the source material to the base body during second time period; selectively growing a second portion of the nitride semiconductor layer on the base body during the second time period wherein the second portion is grown over a second each along the plane that is substantially parallel to the principle plane; and forming the nitride semiconductor wherein the second area of the selectively grown nitride layer is equal to or less than the first area of the selectively grown nitride layer and wherein the second amount of the source material is equal to or less than the first amount of the source material; wherein the nitride semiconductor layer comprises a mixed crystal containing indium.
