Claim 7:
8. A semiconductor processing device, comprising:
a first chamber having an internal volume defined by a side wall, a floor, and a lid;
a first gas distributor having a plurality of gas flow openings formed therethrough; and
a first substrate support disposed in the internal volume of the chamber, the first substrate support comprising:
a first heating element disposed in the first substrate support;
a second heating element disposed in the first substrate support beneath the first heating element and extending radially outward beyond the first heating element; and
a first thermocouple disposed in the first substrate support beneath the second heating element; and

a second chamber having an internal volume defined by a side wall, a floor, and a lid;
a second gas distributor having a plurality of gas flow openings formed therethrough; and
a second substrate support disposed in the internal volume of the chamber, the second substrate support comprising:
a third heating element disposed in the second substrate support;
a fourth heating element disposed in the second substrate support beneath the third heating element and extending radially outward beyond the third heating element; and
a second thermocouple disposed in the second substrate support beneath the fourth heating element.
