Definitions

  • the present invention relates to a ceramic heater, and more particularly, to a ceramic heater incorporating a heating circuit and a separate temperature sensor circuit therein, which is manufactured by a cofiring process based on a precision circuit forming technique, such as screen printing or photolithography, and a layering technique.
  • a precision circuit forming technique such as screen printing or photolithography
  • a conventional ceramic heater is composed simply of a heating circuit, and its temperature is controlled by an analogue or digital method.
  • each temperature control method using the conventional heater has the following problems.
  • the analogue method reads a change in the resistance with respect to the temperature of the heating circuit itself, to thereby detect the temperature.
  • a problem of this method is that it cannot raise the temperature quickly enough because resistance reading and voltage application should be switched by turns.
  • the digital method uses an external, removable temperature sensor.
  • Such an external removable temperature sensor shows large differences (2O 0 C) in temperature sensing, depending upon its locations and attachment methods. Therefore, it is very difficult to precisely control the temperature, which makes temperature control through the digital method uneasy. Disclosure of Invention

  • the temperature control can be made digitally, so that heaters requiring high precision temperature control can remarkably improve their performances.
  • the present invention can be advantageously employed in ceramic heaters in various shapes such as a plate shape (circular and rectangular), cylindrical, cubic structure and the like.

Thereafter, the pattern of the remaining temperature sensor circuit or heating circuit is formed on the upper portion of the second board 16 by a photolithographic technique in the same manner followed by being deposited.

  • the temperature sensor circuit 12 is closely adhered to the heating circuit 14 having the board 18 being in the middle, so it is not directly affected by heat generated by the heating circuit 14, thereby preventing any damage from the heat.
