  • Patent number: 7033444
    Abstract: An electrode structure used in a plasma processing apparatus which performs a predetermined process on an object (W) to be processed by using a plasma in a process chamber (26) in which a vacuum can be formed. An electrode unit (38) has a heater unit (44) therein. A cooling block (40) having a cooling jacket (58) is joined to the electrode unit (38) so as to cool the electrode unit. A heat resistant metal seal member (66A, 66B) seals an electrode-side heat transfer space (62, 64) formed between the electrode unit and the cooling block. Electrode-side heat transfer gas supply means (94) supplies a heat transfer gas to the electrode-side heat transfer space. Accordingly, a sealing characteristic of the electrode-side heat transfer space does not deteriorate even in a high temperature range such as a temperature higher than 200° C. and, for example, a range from 350° C. to 500° C., and the heat transfer gas does not leak.

  • Patent number: 5956837
    Abstract: After the release of the application of an attraction voltage to an electrostatic chuck that is attracting a semiconductor wafer, the wafer is pushed upward by lifting pins through only a very small projection distance. Immediately after processing has ended, the temperature of the wafer is several tens of degrees higher than that of the electrostatic chuck so that, if the wafer has detached, the temperature of the rear surface thereof will fall toward the original temperature of the electrostatic chuck. If the wafer has not detached, the temperature thereof will not fall. Therefore, a determination is made as to whether the wafer has detached or whether it is being subjected to residual attraction, based on temperature change data obtained for the wafer in combination with the electrostatic chuck, by a temperature sensor after the wafer has been pushed upward by a very small projection distance. If there is residual attraction, wafer transfer is halted.
