This invention relates to the field of semiconductor technology and discloses a surface planarization method for epitaxial group III nitride materials based on a 3D mask substrate. The method includes using an etchant to achieve anisotropic etching rate differences between the c, a, and m faces of the group III nitride material, thereby performing surface planarization on the epitaxially grown group III nitride material layer. The surface planarization process is a solution etching process. This invention only requires placing the epitaxial group III nitride material on the 3D mask substrate in a mixed solution of potassium hydroxide and sodium chloride or a mixed solution of phosphoric acid and sodium chloride under specific conditions for chemical wet etching. Sodium chloride can increase the etching rate difference between the horizontal and vertical surfaces of the uneven epitaxial GaN layer, while potassium hydroxide or phosphoric acid solutions will etch the protruding parts of the uneven epitaxial group III nitride material layer surface, making the GaN thickness uniform throughout the entire epitaxial wafer, thus achieving global planarization.
