Publication number: 20140256147Abstract: Advantages of a conventional upper electrode DC power applying manner can be maintained and disadvantages of the upper electrode DC power applying manner can be removed. In a capacitively coupled plasma processing apparatus, a first high frequency power RFH for plasma generation and a second high frequency power RFL for ion attraction are overlapped with each other to be applied to a susceptor (lower electrode) 16. Further, an AC power having a preset frequency is applied to an upper electrode 46 via a matching unit 66 and a blocking capacitor 68 from an AC power supply 64. Furthermore, the AC power has a frequency, which ions in plasma can follow, and the AC power supply 64 can vary a power, a voltage peak value, or an effective value the AC power.Type: ApplicationFiled: September 25, 2012Publication date: September 11, 2014Applicant: Tokyo Electron LimitedInventors: Hikaru Watanabe, Masanobu Honda
