  • Patent number: 11961719
    Abstract: Provided is a vacuum processing method capable of preventing particles from adhering to a wafer due to a titanium (Ti)-based reaction product. The vacuum processing method is applicable to a plasma processing apparatus including: a sample stage disposed in a processing chamber inside a vacuum container, on which a wafer having a titanium (Ti)-containing film is placed; a coil supplied with a radio frequency power for forming plasma in the processing chamber; and a heating device that emits an electromagnetic wave for heating the wafer placed on an upper surface of the sample stage. The vacuum processing method includes a step of etching the titanium (Ti)-containing film, and a step of cleaning an inside of the processing chamber by using a mixed gas of nitrogen trifluoride (NF3) gas, argon gas, and a chlorine gas.

  • Publication number: 20020073582
    Abstract: A pinholed board 22, as provided with a plurality of pinholes 30 determined according to a material number, is attached to a rubber container 24 containing a rubber material, and this rubber container 24 is transferred to a rubber reserving section 16. At a molding step 18, there is displayed a condition table 36 according to working conditions. The condition table 36 is provided with a attaching base 42 of the board 22, and the attaching base 42 is provided with a number of projections 46 determined according to the number of the rubber material to be worked, so that the board 22 having the same material number can be exclusively attached. The molding work is not started before the rubber container 24 is transferred from the rubber reserving section 16 to the molding step 18 and before the board 22 attached to the rubber container 24 is attached to the attaching base 42 of the condition table 36.
