Abstract

The invention belongs to a ruthenium plating technical process and particularly relates to a pretreatment process of a vacuum ruthenium plating technology. The pretreatment process comprises the following steps that 1, a molybdenum sheet is placed into an electrolytic tank to be subjected to an electrolytic degreasing reaction and then is washed out through pure water; 2, the washed molybdenum sheet is added into mixed acid liquor to be subjected to surface film removing treatment and then washed out through pure water; 3, the molybdenum sheet subjected to film removing treatment is placed into vacuum equipment to be subjected to a vacuumizing heating reaction; and 4, the temperature is constant, the molybdenum sheet is subjected to plasma cleaning, and after cleaning is finished, the pretreated molybdenum sheet is obtained in a cooled mode. The problems that in the prior art, pollution is large, and the adhesion effect is poor are solved, through an alkali electrolysis plus mixed acidcleaning plus plasma cleaning combined technology, the cleanliness degree of the surface of the molybdenum sheet is effectively increased, and binding force between the molybdenum sheet and a ruthenium layer is increased.

Description

technical field [0001] The invention belongs to the technical process of ruthenium plating, and in particular relates to a pretreatment process of vacuum ruthenium plating technology. Background technique [0002] At present, there are many factors affecting the quality of the magnetron sputtering coating film, voltage, power, argon gas pressure, molybdenum sheet surface condition, etc. all have a great influence on the film formation, and among them, the molybdenum sheet surface condition is the most important , if the surface oxidation degree of the molybdenum sheet is high, and there are many organic substances such as grease, it will have an unimaginable impact on the surface bonding force, corrosion resistance and electrical properties after ruthenium plating. Not only will the molybdenum sheet coating fall off, but the oxygen content If it is too high, the surface resistance will increase and the electrical performance will decrease. Since the vacuum coating cannot be...
