PLASMA PROCESSING APPARATUS AND PLASMA PROCESSING METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18392294 titled 'PLASMA PROCESSING APPARATUS AND PLASMA PROCESSING METHOD
Simplified Explanation
The patent application describes a plasma processing apparatus that adjusts the frequencies of radio-frequency power in each bias cycle of electrical bias energy to improve the match based on an evaluation value.
- The radio-frequency power supply adjusts frequencies of radio-frequency power in each bias cycle of electrical bias energy.
- It uses a reference time series of frequencies of the radio-frequency power in each bias cycle.
- The radio-frequency power supply repeats using a changed time series of frequencies to increase the match based on an evaluation value.
- The changed time series results from shifting the reference time series by a phase shift amount, scaling the reference time series in a frequency direction, or scaling multiple time zones of the reference time series in a time direction.

Original Abstract Submitted
In a plasma processing apparatus, a radio-frequency power supply adjusts frequencies of radio-frequency power in each bias cycle of electrical bias energy. The radio-frequency power supply uses a reference time series of frequencies of the radio-frequency power in each bias cycle. The radio-frequency power supply repeats using a changed time series of frequencies of the radio-frequency power in each bias cycle to increase a degree of match based on an evaluation value. The changed time series results from shifting the reference time series by a phase shift amount, scaling the reference time series in a frequency direction, or scaling two or more of multiple time zones of the reference time series in a time direction.
