In one embodiment, a substrate processing apparatus, includes: a chamber; a first electrode disposed in the chamber; a second electrode disposed in the chamber to face the first electrode, and to hold a substrate; an RF power supply to apply an RF voltage with a frequency of 50 MHz or more to the second electrode; and a pulse power supply to repeatedly apply a voltage waveform including a negative voltage pulse and a positive voltage pulse of which delay time from the negative voltage pulse is 50 nano-seconds or less to the second electrode while superposing on the RF voltage. |
