The present invention is to provide a method for forming a compound epitaxial layer by chemical bonding, which comprises the steps of forming a contact layer on a substrate; chemically reacting atoms on a surface of the contact layer with non-metal atoms, such that the non-metal atoms form non-metal ions for chemically bonding to the atoms on the surface of the contact layer; exciting the non-metal ions by energy excitation, such that unpaired electrons of the non-metal ions not yet bound to the atoms on the surface of the contact layer become dangling bonds; and conducting chemical vapor deposition by introducing an organic metal compound and a reactant gas, wherein metal ions of the organic metal compound are bound to the dangling bonds by electric dipole attraction, and anions of the reactant gas are bound to the metal ions by ionic bonding, such that the compound epitaxial layer is formed. |
