Problems solved by technology

[0004] However, when the target material is aluminum, due to the low hardness of metal aluminum, it is easy to rub against the coating probe during the process of surface metallization (also known as coating), forming an Al-Cu alloy and floating on the surface of the target material. , and wrap the coating probe, which seriously affects the effect of surface metallization, and finally reduces the binding rate of the target

Abstract

The invention discloses a binding method for an aluminum rotating target, and belongs to the field of sputtering target preparation. The binding method of the aluminum rotating target according to the present invention firstly performs coating metallization treatment on the back tube and the target material under specific conditions, and then performs heating and binding of the two, which can effectively maintain the wettability of the solder while maintaining the solder wettability. To avoid alloy impurities generated during the binding process of the target, the aluminum rotating target has a high binding rate and high production efficiency after being processed.

Description

technical field [0001] The invention belongs to the field of sputtering target preparation, in particular to a binding method for an aluminum rotating target. Background technique [0002] At present, the targets used in the sputtering coating industry are usually manufactured by bonding and binding. The rotating target is generally bound on a stainless steel back tube or a titanium back tube. The binding process commonly used in the target binding process The solder is metallic indium or other metallic substances. [0003] High-quality targets are the basis for thin film applications, and the target binding associated with the target also affects the quality of the thin films. Target binding is a target deep processing technology, that is to use materials with good wettability and ductility to bond the target and the backplane together, and the formed bonding layer has certain electrical conductivity, thermal conductivity and Adhesive strength, the wettability between the...
