Problems solved by technology

In addition, because the centering of the target tube and the liner is not easy to achieve, the thickness of the adhesive layer or weld layer is not uniform, especially along the direction of the tube target axis
These will have adverse effects on the sputtering process

Abstract

The invention relates to a tubular target bonding method for bonding a tubular target and a metal lining tube. The method makes the whole tubular target with large length be bonded with the metal lining tube in high quality; and the high quality bonding is concretely embodied in cases that the weld thickness is controlled, the weld thickness can be reduced to a common weld thickness of a planar target, even thinner, and the uniformity of the weld thickness can be maintained. The method is beneficial to the welding flux saving and target use performance improvement. The method is suitable for the production of the tubular target with certain plasticity, and the plasticity of the tubular target satisfies requirements of a cold drawing technology.

Description

technical field [0001] The invention relates to a bonding method for a tubular target material used for bonding a tubular target material and a metal liner. Background technique [0002] According to different shapes, sputtering targets can be divided into two categories: planar targets and tubular targets (also called rotating targets or hollow cylindrical targets). The sputtering utilization rate of the former is about 30%, while the utilization rate of the latter can be as high as 80%. more and more. Known tubular targets include metals, such as Ag, Al, Ti tubular targets, and ceramics, such as AZO (zinc aluminum oxide), ITO (indium tin oxide), Si3N4 (silicon nitride) tubular targets. Some metal targets, especially metal or alloy targets with relatively low melting point and strength, are prone to creep during the sputtering process, which affects the sputtering process. These metal or alloy targets need to be bonded to another material with high strength and not easy ...
