Abstract:
Embodiments of the present disclosure generally relate to methods and apparatus for visual lamp failure detection in a processing chamber, such as an RTP chamber. Visual feedback is facilitated through the use of a wide-angle lens positioned to view lamps within the process chamber. The wide-angle lens is positioned within a probe and secured using a spring in order to withstand high temperature processing. A camera coupled to the lens is adapted to capture an image of the lamps within the process chamber. The captured image of the lamps is then compared to a reference image to determine if the lamps are functioning as desired.
