Abstract

A furnace incorporating a novel thermal design is disclosed. Heating element temperature is reduced compared to conventional designs while providing a precisely controlled process temperature in the range1000 - 1400 degrees centigrade. The furnace uses a plurality of Kanthal heating elements arranged in a planar array as close to the work as possible thus approximating an isothermal condition with respect to the work. Means are provided for bringing the heating elements into the process chamber. Further, the process chamber is made of aluminum and its internal surfaces are highly polished to reflect heat. The chamber walls have built in active cooling to carry non-reflected heat away. The heating elements are modular to facilitate removal and replacement without disassembly of the furnace. The configuration of the heating elements is linear rather than coiled and the temperature is monitored directly by measuring the electrical resistance of the Kanthal wires.

AMENDED CLAIMS [received by the International Bureau on 26 October 2004 (26.10.2004); new claims 15, 16 and 17 added; remaining claims unchanged (1 page)]
[15] 15. A cold wall furnace comprising: reflective aluminum walls defining a process chamber; a plurality of feed-through openings provided in opposed walls of the furnace; and, a plurality of modular, insertable heating elements, each comprising resistive kanthal wires enclosed in an alumina sleeve, such that each alumina sleeve isolates its enclosed kanthal wires from a workpiece in the process chamber; wherein, the heating elements may be inserted into or removed from the process chamber without disassembling the furnace,
[16] 16. A heating element comprising: an alumina sleeve; a resistive kanthal wire bonded to nichrome at each end, the wire being enclosed in the alumina sleeve; and, a connector assembly in electrical contact with the wire such that the heating element may be inserted into or removed from a process chamber without disassembling the process chamber. [17] 17. A heating element comprising: an alumina sleeve; and, a resistive wire, comprising an alloy of nickel, iron and aluminum such as kanthal, such that at high temperatures aluminum oxide is formed on the surface of the wire creating a compatible surface for contact with the alumina sleeve.
