Claim 8:
9. A method of manufacturing a temperature-controlled substrate support for a substrate processing system, comprising:
embedding N resistive heaters in N zones of a substrate support;
embedding a temperature sensor in one of the N zones of the substrate support;
measuring N resistances of the N resistive heaters in the N zones of the substrate support;
determining N−1 resistance ratios based on the N resistances;
connecting a controller to the N resistive heaters and the temperature sensor; and
programming the controller to control temperature in N−1 of the N resistive heaters in N−1 of the N zones, respectively, during operation of the substrate processing system in response to:
a measured temperature in the one of the N zones;
the N resistances of the N resistive heaters; and
the N−1 resistance ratios.
