    • PURPOSE: A gallium nitride substrate and a manufacturing method thereof are to utilize the gallium nitride substrate as semiconductor electronic elements such as LED, LD etc., thereby reducing a manufacturing cost and providing an excellent crystalline. CONSTITUTION: A method comprises the steps of: preparing a silicon base(100) having a silicon plate; forming a first buffer layer(200) consisting of a compound having the lattice parameter close to the gallium nitride; growing a second buffer layer(300) consisting of the gallium nitride on the first buffer layer; and forming a thick film(400) of the gallium nitride on the second buffer layer.
