主权项 1. A method of manufacturing a semiconductor device, the method comprising: introducing a substrate in a chamber; and forming an InAlGaN layer on the substrate, the InAlGaN layer having an upper side and a lower side, wherein an In composition of the upper side of the InAlGaN layer is smaller than that of the lower side of the InAlGaN layer, wherein a supply amount of an In containing gas for source gases of the upper side of the InAlGaN layer is greater than that of the lower side of the InAlGaN layer, wherein the growth temperature of the upper side of the InAlGaN layer is higher than that of the lower side of the InAlGaN layer.
