Abstract: This application provides an organic mixed metal-oxygen cluster compound, and a chemical general formula thereof is as follows: (M1)a(M2)b(M3)cOg(L1)x(L2)y(L3)z, where M1 is selected from at least one of Ti, Zr, and Hf; M2 is selected from at least one of Bi, Te, Sn, Pt, Ag, and Au; M3 is selected from one of Fe, Ni, Co, and Cu; L1, L2, and L3 are respectively selected from organic ligands that directly coordinate with a metal and include one of O, S, Se, N, and P that serves as a ligating atom; a, b, g, x, y, and z are all natural numbers greater than or equal to 1; and c is a natural number greater than or equal to 0. This application further provides a patterning material including the organic mixed metal-oxygen cluster compound, a semiconductor device including the patterning material, a terminal, and a substrate surface patterning method.

Abstract: This application relates to a patterning material, a patterning composition, and a pattern forming method. The patterning material in this application includes a metal-oxygen cluster framework, a radiation-sensitive organic ligand, and a second ligand. The radiation-sensitive organic ligand coordinates with a metal M through a coordination atom. The coordination atom is at least one of: an oxygen atom, a sulfur atom, a selenium atom, a nitrogen atom, or a phosphorus atom. The radiation-sensitive organic ligand is a monodentate ligand or a polydentate ligand with a denticity of two or more. The second ligand is an inorganic ion or a coordination group.
