Abstract: A method includes: receiving a first signal from a first sensor at a first filter and preventing passage of a first portion of the first signal via the first filter. The first portion of the first signal is at a first RF. A second portion of the first signal is indicative of a first temperature of a first electrode in a plasma chamber. The method further includes: outputting a second signal from the first filter; receiving the second signal at a second filter; and preventing passage of a portion of the second signal via the second filter. The portion of the second signal is at a second RF. The second RF is less than the first RF. The first filter and the second filter are implemented on a printed circuit board. The method further includes adjusting a temperature of the first electrode based on an output of the second filter.

Abstract: A processing chamber includes an upper surface and a showerhead arranged to supply gases through the upper surface into the processing chamber. At least a portion of the showerhead extends above the upper surface of the processing chamber. A shroud enclosure is arranged on the upper surface of the processing chamber. The shroud enclosure is arranged around the portion of the showerhead extending above the upper surface of the processing chamber and is configured to isolate radio frequency interference generated by the showerhead.

Abstract: A substrate processing system includes an upper electrode and a lower electrode arranged in a processing chamber. A gas delivery system is configured to selectively deliver at least one of a precursor gas, one or more deposition carrier gases, and a post deposition purge gas. An RF generating system is configured to deposit film on a substrate by generating RF plasma in the processing chamber between the upper electrode and the lower electrode while the precursor gas and the one or more deposition carrier gases are delivered by the gas delivery system. A bias generating circuit is configured to selectively supply a DC bias voltage to one of the upper electrode and the lower electrode while the post deposition purge gas is delivered by the gas delivery system. The post deposition purge gas that is delivered by the gas delivery system includes a reactant gas.

Abstract: A method for processing a substrate in a substrate processing system includes selectively delivering at least one of a precursor, a deposition carrier gas, and a post deposition purge gas to a processing chamber. The method includes depositing film on the substrate by generating radio frequency (RF) plasma in the processing chamber between an upper electrode and a lower electrode while supplying an RF voltage to one of the upper electrode and the lower electrode and while the precursor and the deposition carrier gas is delivered. The method includes selectively supplying a direct current (DC) bias voltage to the upper electrode or the lower electrode; moving the substrate relative to a pedestal supporting the substrate while generating the DC bias voltage; and delivering the post deposition purge gas while supplying at least a portion of the DC bias voltage to the upper electrode or the lower electrode.

The first filter assembly includes a first filter and a second filter. The first filter receives a first signal from a first sensor, prevents passage of a first portion of the first signal and outputs a second signal. The first portion of the first signal is at a first radio frequency. A second portion of the first signal is indicative of a first temperature of a first electrode in a plasma chamber. The second filter receives the second signal and prevents passage of a portion of the second signal. The portion of the second signal is at a second radio frequency. The second radio frequency is less than the first radio frequency. The controller adjusts a temperature of the first electrode based on an output of the second filter.

Abstract: The present invention relates to a personal user agent acting on behalf of a group of member device agents in a communication network. The personal user agent provides its group of member device agents with a specialized proxy function, while representing the group to the network as a single user agent. To devices on the communication network, the personal user agent behaves and is viewed as a user agent. To the group of member device agents, the personal user agent behaves and is viewed as both a registrar and a proxy server.
