发明名称 Use of variable impedance to control coil sputter distribution
摘要 <p>Variable reactances in an impedance-matching box for an RF coil, in a plasma deposition system for depositing a film of sputtered target material on a substrate, can be varied during the deposition process so that the RF coil and substrate heating, and the film deposition, are more uniform due to "time-averaging" of the RF voltage distributions along the RF coil. &lt;IMAGE&gt;</p>
