    摘要: A process chamber 55 for processing a semiconductor substrate 60 in a plasma, comprises a process gas distributor 100 for distributing process gas into a plasma zone 65 in the chamber. An inductor antenna 135 is used to form an inductive plasma from the process gas in the plasma zone. A primary bias electrode 145 on a ceiling 140 of the chamber 55 has a conducting surface 150 exposed to the plasma zone 65. A dielectric member 155 comprising a power electrode 165 embedded therein, has a receiving surface for receiving a substrate 60. A secondary bias electrode 170 below the dielectric member 155 has a conducting surface 175 exposed to the plasma zone 65. An electrode voltage supply 180 maintains the power electrode 165, primary bias electrode 145, and secondary bias electrode 170, at different electrical potentials to provide a high density, highly directional, plasma in the plasma zone 65 of the chamber 55.

    摘要: A failure resistant electrostatic chuck 20 for holding a substrate 35 during processing of the substrate 35, is described. The chuck 20 comprises a plurality of electrodes 25 covered by an insulator 30, the electrodes 25 capable of electrostatically holding a substrate 35 when a voltage is applied thereto. An electrical power bus 40 has a plurality of output terminals 45 that conduct voltage to the electrodes 25. Fuses 50 electrically connect the electrodes 25 to the output terminals 45 of the power bus 40, each fuse 50 connecting at least one electrode 25 in series to an output terminal from the power bus 40. The fuses 50 are capable of electrically disconnecting the electrode 25 from the output terminals 45 when the insulator 30 punctures and exposes the electrode 25 to the process environment causing a current to flow through the fuse 50. A current detector 175 and electrical counter 180 can be used to provide early detection and counting of the number of failures of the electrodes 25 by detecting the current discharges through the fuses 50.

    摘要: A semiconductor wafer support chuck having small diameter gas distribution ports for heat transfer gas. The diameter ports inhibit plasma ignition in heat transfer gas distribution channels. The ports are less than 20 mils in diameter less than 3 mm in length. The short length of the ports facilitates fabrication of multiple ports of very small diameter. The ports communicate with a gas distribution plenum integrated into the body of the chuck beneath a wafer support surface. The plenum has radial channels and a peripheral groove for distributing heat transfer gas to the wafer support surface.
