Product advantages

The sputtering targets of Guoxi Works feature the following advantages:

  • They are made of high purity materials.
  • Thanks to our unique control of the material properties such as metal structure and orientation, the generation of particles is minimized and excellent uniformity of the film thickness as well as the film characteristics are maintained.
  • The particle generation is also minimized out of the powder metal targets due to high degree of density.
  • Thanks to the uniformity of the sputtering targets, only a short burn-in time is required for the initial stage of sputtering our new targets.
  • In order to cope with the trend of using high power in sputtering, we supply backing plates backing plates of a variety of materials and make and feature diffusion bonding with various different materials.

How to produce


  • First, our workers cut,cleanout the 99.995% pure copper material ,and then put them into the equipment  which can purify 99.99995% pure copper from 99.995% pure copper material. In the purification process,our professional workers can control the electricity,the rate of circulation and temperature.And they also can put additive into the electrolyte.
  • In short ,We mainly adopt electrolytic refining method which is used to obtain high purity copper.The pocess is highly purified of electrolyte with a higher purity of copper electrolysis again.
  • Depending on the type of electrolyte, the system can be divided into three kinds. First, the copper sulfate solution;Second,copper nitrate solution;Third,copper sulfate solution and copper nitrate solution.
