  • Publication number: 20190366459
    Abstract: A method for the repair of a heater, or an electrostatic chuck, using a ceramic top layer joined with a hermetically sealed joint. The heater or electrostatic chuck may be machined down to remove a damaged top surface, and to allow for the joining of a new top surface. The new top pieces may be aluminum nitride and the pieces may be brazed with an aluminum alloy under controlled atmosphere. The joint material is adapted to later withstand both the environments within a process chamber during substrate processing, and the oxygenated atmosphere which may be seen within the shaft of a heater or electrostatic chuck.
    Type: Application
