Abstract:
An active real-time characterization system for detecting unwanted elements and/or physical imperfections on a semiconductor wafer during manufacturing. Infrared and visible light sources output beams of coherent light directed at a particular area on the semiconductor wafer via associated polarizing control elements. A series of cameras, including a visible light camera, a visible light second harmonic generation camera, an infrared camera, an infrared second harmonic generation camera, a sum-frequency camera and a third-order camera are configured to receive return beams of light via associated polarizing control elements. The polarizing control elements include a polarizer, a quarter wave plate and/or a half wave plate. A processor processes the signals received from the cameras to detect unwanted elements and/or physical imperfections on the semiconductor wafer.

Claim (Index 11):
The active real-time characterization system of  claim 10 , further comprising:\n a second visible light source for outputting a second beam of coherent visible light and an associated polarizing control element, the second visible light source configured to direct the second beam of coherent visible light at the same particular area on the semiconductor wafer through the associated polarizing control element; a sum-frequency camera and an associated polarizing control element, the sum-frequency camera configured to receive a fourth return beam of light from the particular area on the semiconductor wafer through the associated polarizing control element; and wherein the processor is configured to receive second signals from the sum-frequency camera and to process the second signals from the sum-frequency camera in addition to the first signals from the visible light camera, the visible light second harmonic generation camera, the infrared camera, and the infrared second harmonic generation camera to detect the unwanted elements or the physical imperfections on the semiconductor wafer.
