Abstract:
A method for fabricating a compound semiconductor epitaxial wafer wherein a periodic table group III source gas and a periodic table group V source gas are supplied into a reaction furnace of a vapor phase growth apparatus to epitaxially grow a compound semiconductor film on main surfaces of a plurality of compound semiconductor wafers arranged within said reaction furnace, said method comprising the steps of:flowing said group III source gas from one end of said reaction furnace to the other end thereof in such a manner that a flow path of the group III source gas is established along an array direction of said plurality of compound semiconductor wafers;supplying as dispersedly said group V source gas from a plurality of locations at halfway of the flow path of said group III source gas: andwherein the supply positions of said group V source gas are set so that a vertical distance between said supply positions and the main surfaces of said compound semiconductor wafers is not smaller than 1 mm and not larger than 20 mm.
