  • HIGH TEMPERATURE RESISTANT SILICON JOINT FOR THE JOINING OF CERAMICS
    Publication number: 20210086277
    Abstract: A method for the joining of ceramic pieces with a hermetically sealed joint comprising brazing a layer of joining material between the two pieces. The ceramic pieces may be aluminum nitride or other ceramics, and the pieces may be brazed with a high purity silicon or a silicon 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 interior of a heater or electrostatic chuck.
    Type: Application
