  • Patent number: 7175737
    Abstract: This application discloses the structure of an ESC stage where a chucking electrode is sandwiched by a moderation layer and a covering layer. The moderation layer and the covering layer have the thermal expansion coefficients between the dielectric plate and the chucking electrode. This application also discloses optimum total thickness of the ESC stage, optimum volume ratio of composite which the moderation layer is made of, and an optimum range of the thermal expansion coefficient of the composite. This application further discloses a substrate processing apparatus for carrying out a process onto a substrate as the substrate is maintained at a temperature higher than room temperature, comprising the electrostatic chucking stage for holding the substrate during the process.

  • Patent number: 6770146
    Abstract: The present invention is generally directed to a system and process for rotating semiconductor wafers in thermal processing chambers, such as rapid thermal processing chambers and chemical vapor deposition chambers. In accordance with the present invention, a semiconductor wafer is supported on a substrate holder which, in turn, is supported on a rotor. During processing, the rotor is magnetically levitated and magnetically rotated by suspension actuators and rotation actuators positioned outside of the chamber.
