摘要: After etching a polysilicon film, when a protective film made of a carbon polymer is formed on a sidewall of the polysilicon film using plasma containing carbons, a metallic material as a lower film is etched using plasma containing a halogen gas under an etching condition in which volatility is improved due to the rise in a wafer temperature or the low pressure of a processing pressure, thereby preventing a side etching and unevenness of a sidewall of the polysilicon film. Further, by using the protective film made of a carbon polymer, metallic substances scattered at the time of etching the metallic material are not directly attached to the polysilicon film, but can be simply removed along with the protective film made of a carbon polymer in an asking step.

摘要: Plasma processing of plural substrates is performed in a plasma processing apparatus, which is provided with a plasma processing chamber having an antenna electrode and a lower electrode for placing and retaining the plural substrates in turn within the plasma processing chamber, a gas feeder for feeding processing gas into the processing chamber, a vacuum pump for discharging gas from the processing chamber via a vacuum valve, and a solenoid coil for forming a magnetic field within the processing chamber. At least one of the plural substrates is placed on the lower electrode, and the processing gas is fed into the processing chamber. RF power is fed to the antenna electrode via a matching network to produce a plasma within the processing chamber in which a magnetic field has been formed by the solenoid coil. This placing of at least one substrate and this feeding of the processing gas are then repeated until the plasma processing of all of the plural substrates is completed. An end of seasoning is determined when a parameter including an internal pressure of the processing chamber has become stable to a steady value with plasma processing time.

摘要: If the energy service enterprise is responsible for paying costs for applying energy-saving measures to the object facilities, measures the energy consumption after taking the energy-saving measures, calculates the amount of curtailed energy cost by comparing the measured value with the energy consumption before taking the energy-saving measures previously stored in the database, and receives at least a part of the curtailed amount, the customer is not required to plan equipment investment in energy-saving measures and collection thereof. Introduction of the energy-saving measures is thus made easier.
