等离子体处理装置和等离子体处理方法
摘要：
本发明提供一种等离子体处理装置和等离子体处理方法。目的在于在腔室内的电极上形成作为靶发挥功能的膜并对所形成的膜进行溅射。在该等离子体处理装置中，载置基板的第一电极与同上述第一电极相向地配置的第二电极以隔开规定的间隙的方式相向地配置，该等离子体处理装置具有：第一高频电源，其向上述第二电极供给第一高频电力；直流电源，其向上述第二电极供给直流电力；以及气体供给源，其向腔室内供给气体，上述第二电极具有利用通过供给第一气体和上述第一高频电力而生成的等离子体形成的反应产物的膜，上述第二电极成为利用通过供给第二气体、上述第一高频电力以及上述直流电力而生成的等离子体对上述反应产物的膜进行溅射的靶。
摘要（英）：

A plasma processing apparatus includes a first electrode, a second electrode disposed to face the first electrode, a chamber, a first high-frequency power supply, a direct-current power supply, and a gas supply source. The plasma processing apparatus generates first plasma to form a film of a reaction product on the second electrode by causing the first high-frequency power supply to supply first high-frequency power to the second electrode and causing the gas supply source to supply a first gas into the chamber; and generates second plasma to sputter the film of the reaction product by causing the first high-frequency power supply to supply the first high-frequency power to the second electrode, causing the direct-current power supply to supply direct-current power to the second electrode, and causing the gas supply source to supply a second gas into the chamber.
