Plasma processing apparatus.

摘要

A plasma processing apparatus has a second electrode set parallel to a first electrode to be set in a deposition chamber capable of being set in an airtight vacuum, and an RF power supply path for applying an RF power having a discharge frequency of 20 MHz to 450 MHz to the second electrode. In the plasma processing apparatus, a high-voltage capacitor having a small capacitance is arranged on the RF power supply path. With this arrangement, the plasma processing apparatus capable of uniformly, stably processing a relative large base with a plasma at a high processing speed is provided. Further, the plasma processing apparatus in which the manufacturing time can be shortened and cost can be decreased is provided.
