Abstract

A heater is provided that includes a first power pin made of a first conductive material, a second power pin made of a second conductive material that is dissimilar from the first conductive material of the first power pin, and a resistive heating element having two ends and made of a material that is different from the first and second conductive materials of the first and second power pins. The resistive heating element forms a first junction at one end with the first power pin and a second junction at its other end with the second power pin, and changes in voltage at the first and second junctions are detected to determine an average temperature of the heater.

Abstract

An assembly, for example an electrostatic chuck, is provided including a substrate, an electrostatic chuck, a heating plate, and a bond layer comprising a phosphorescent material. In one form, an optical sensor is disposed proximate the bond layer to detect a temperature of the bond layer in the field of view of the optical sensor. The phosphorescent material is illuminated and the subsequent decay is observed by the optical sensor. From this information, the temperature of the electrostatic chuck and substrate is determined and heating elements may be adjusted by a controller.
