Abstract

The invention relates to a welding method for an ITO target material and a Mo back plate. The welding method comprises the following steps that (1) the ITO target material and the Mo back plate are heated to target temperatures respectively; (2) keeping the temperature of the ITO target material and the Mo back plate unchanged, and infiltrating the welding surface of the ITO target material and the welding surface of the Mo back plate; (3) forming a welding flux groove in the welding surface of the Mo back plate, adding molten welding flux into the welding flux groove, and attaching the ITO target material to the welding flux groove; and (4) a buffer layer is arranged on the surface of the ITO target material, natural cooling is conducted in the pressure applying process, and welding of the ITO target material and the Mo back plate is completed. According to the welding method, the ITO target material and the Mo back plate are not prone to deformation in the welding process, the welding binding rate is high, the welding quality of the ITO target material and the back plate is improved, and the magnetron sputtering quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of semiconductor materials, and relates to a binding method of a target material and a back plate, in particular to a brazing method of an ITO target material and a Mo back plate. Background technique [0002] The sputtering coating technology usually uses gas discharge to generate gas ionization, and its positive ions bombard the cathode target at a high speed under the action of an electric field, knock out the atoms or molecules of the cathode target, and fly to the surface of the substrate to be plated to deposit a film. At present, sputtering coating technologies include radio frequency sputtering, three-stage sputtering and magnetron sputtering. Among them, magnetron sputtering has become the mainstream coating method due to its higher coating rate compared with other sputtering technologies. [0003] ITO (Indium Tin Oxide) target is the raw material for the production of ITO film. The binding quality ...
