  • Apparatus for positioning a furnace module in a horizontal diffusion furnace
    Patent number: 5530222
    Abstract: Performance of a high temperature diffusion furnace is enhanced by an improved multi-furnace module design. The furnace is constructed of materials suitable for clean room environments with an adjustable leveling frame assembly. A slide out assembly and heating element alignment mechanism of individual furnace tube modules with a heating element hoist mechanism allows for enhanced maintainability. Heat treatment performance is improved by a sealed heating element with individual furnace module cooling system. Improved thermocouple positioning and composition has also enhanced heat treatment process control and heating element maintainability.
    Type: Grant
    Filed: April 21, 1994
    Date of Patent: June 25, 1996
    Assignee: Thermtec, Inc.
