20210183629 | RING ASSEMBLY, SUBSTRATE SUPPORT ASSEMBLY AND SUBSTRATE PROCESSING APPARATUS - Provided is a technique capable of adjusting an angle of incidence of ions. Provided is a ring assembly including: a conductive edge ring; an insulating annular member including at least an inner peripheral portion disposed on the edge ring; and a conductive member disposed on at least a portion of an upper surface of the annular member overlapping with the edge ring in top plan view. | 2021-06-17 |
20210183630 | PLASMA PROCESSOR - A plasma processing apparatus, for releasing plasma-converted gas from plasma head for performing process, detects the pressures of a gas prior to application of a voltage to electrodes of the plasma head, the gas being supplied from gas supply section to a plasma head, and allow initiation of process by the plasma processing apparatus based on the detected pressures. | 2021-06-17 |
20210183631 | PLASMA PROCESSING APPARATUS AND PLASMA PROCESSING METHOD - A chamber is configured to process a substrate by using a plasma. A heater is disposed in a region within the chamber which is not exposed to the plasma and a radio frequency power supplied for plasma formation. A heater power supply is configured to supply a pulsed power to the heater. | 2021-06-17 |
