Patent ID: 8242416

Claim:
A method of securing a terminal to a ceramic heater, the ceramic heater including a ceramic substrate and a resistive heating element, the method comprising: forming a recess in the ceramic substrate to expose a portion of the resistive heating element, the recess defining an interior surface, the interior surface including a side surface defining a periphery of the recess and a bottom surface on which the resistive heating element is disposed; applying a material on the side surface of the interior surface of the recess to form an intermediate layer, the material being in a form selected from a group consisting of a paste, a powder and a tape; applying an active brazing material on at least one of the intermediate layer and the bottom surface; and bonding the terminal to the intermediate layer by the active brazing material to electrically connect the terminal to the resistive heating element through the intermediate layer, a portion of the terminal being surrounded by the intermediate layer and the active brazing material.
