  • What are the Preparations for Sputtering Target Before Use?

    Magnetron sputtering is a new type of physical vapor deposition. The electron gun system is used to shoot and focus the electrons on the material to be plated, making the sputtering atoms follow the principle of momentum conversion and fly away from the material with high kinetic energy to the substrate to form a film. This kind of material is called sputtering target. Today, I'd like to talk with you about some preparations before sputtering.
    Sputtering preparation
    It is very important to keep the vacuum cavity, especially the sputtering system clean. Any residue formed by lubricating oil, dust and previous coating will collect moisture and other pollutants, which will directly affect the vacuum degree and increase the possibility of film formation failure. Short circuit or arcing of target, rough film-forming surface and excessive content of chemical impurities are often caused by unclean sputtering chamber, sputtering gun and target.
    1. In order to maintain the composition characteristics of the coating, the sputtering gas (argon or oxygen) must be clean and dry. After the substrate is installed in the sputtering chamber, the air must be extracted to reach the vacuum required by the process.
    2. Dark area shielding cover, cavity wall and adjacent surface also need to be kept clean. When cleaning the vacuum cavity, we suggest to use the glass ball shot blasting method to deal with the dirty parts and use compressed air to remove the sputtering Residue around the cavity at the early stage, and then use the alumina impregnated sandpaper to polish the surface gently. After the paper is polished, it is cleaned with alcohol, acetone and deionized water. At the same time, it is recommended to use industrial vacuum cleaner for auxiliary cleaning.
    3. Vacuum sealed plastic bag packaging, built-in moisture-proof agent.
    4. Do not touch the target directly with your hands when using the target. Please wear clean and lint free protective gloves before using the target. Do not touch the target directly with your hands.
