摘要 |
A microwave plasma processing apparatus comprises a plasma generation chamber, a processing chamber communicating with the plasma generation chamber, supporting of a substrate to be processed arranged in the processing chamber, a circular waveguide with slots arranged around the plasma generation chamber, and a magnetic field generation unit for generating a cusp magnetic field in the plasma generation chamber. A microwave plasma processing method using this apparatus is provided, to maintain a high-density and large-area uniform plasma, even at a low temperature, and even in a low-pressure region having a pressure of 1 mTorr.
