Abstract
This invention relates to a process control system and method of controlling a chemical vapor deposition (CVD) process where a coating is deposited on a substrate heated by passing a current through the substrate to create a heating zone. The control system relies on detecting a signal induced on the coated substrate outside of the heating zone and using the induced signal to control one or more process parameters.
