Abstract :
The reduction of excessively large internal stress to zero has been succeeded by adjusting working gas pressure to the proper value in the range below 1 mtorr in a facing targets sputtering (FTS) system. In addition, the internal stress depends on the distance between facing targets in the FTS system. The origins of such a change of internal stress can be attributed to the bombarding effect by energetic particles recoiled at the target´s surface with a high ejection angle
