Abstract
A material deposition sensor includes a heater and a temperature sensor separated from one another. In operation, the sensor is disposed within a deposition chamber, and material is deposited onto the sensor. When a particular material thickness is deposited, a direct thermally conductive path is created between the heater and temperature sensor, and heat from the heater conducts directly to the temperature sensor. By predetermining a deposition thickness necessary to create the direct thermally conductive path, the deposition thickness can be controlled and/or predicted.
