Abstract:
PROBLEM TO BE SOLVED: To provide a circuit pattern of an ohmic-resistance heating element embedded in a wafer process device used for manufacturing a process. SOLUTION: The wafer process device comprising an optimum electrode pattern for an ohmic-resistance heating element is disclosed. The optimum electrode pattern is so designed as to compensate heat loss in the vicinity by generating more heat near or around a contact area, an electric connection part, and a district such as through hole, to bring about uniformity in maximum temperature. In another embodyment of the optimum design, the resistance of the heating element is closely matched with the impedance of a power supply, for higher efficiency in particular when a higher operation temperature of higher electric output is required.
