Rotatory Tungsten (W) Sputtering Target

Chemical Element


TungstenTungsten, also called wolfram, is a chemical element originated from the Swedish ‘tung sten’ meaning heavy stone(W is wolfram, the old name of the tungsten mineral wolframite). It was first mentioned in 1781 and observed by T. Bergman. The isolation was later accomplished and announced by J. and F. Elhuyar. “W” is the canonical chemical symbol of tungsten. Its atomic number in the periodic table of elements is 74 with location at Period 6 and Group 6, belonging to the d-block. The relative atomic mass of tungsten is 183.84(1) Dalton, the number in the brackets indicating the uncertainty.

Rotatory target and planar target

Comparing with planar targets, rotatory target contains more material and offers a greater utilization, which means longer production runs and reduced downtime of the system, increases the throughput of the coating equipment. Besides, rotatory sputtering target allows the use of higher power densities due to the heat build-up being spread evenly over the surface area of the target. As a consequence, an increased deposition speed can be seen along with an improved performance during reactive sputtering.

Due to project needs, I have been looking for rotary tungsten rotating targets and I finally find those with high purity and good price. The result is that these products worked very well
