    Abstract: A focus height sensor in an optical system for inspection of semiconductor devices includes a sensor beam source that emits a beam of electromagnetic radiation. A reflector receives the beam of electromagnetic radiation from the sensor beam source and directs the beam toward a surface of a semiconductor device positioned within a field of view of the optical system. The reflector is positioned to receive at least a portion of the beam back from the surface of the semiconductor device to direct the returned beam to a sensor. The sensor receives the returned beam and outputs a signal correlating to a position of the surface within the field of view along an optical axis of the optical system.

    Abstract: A method of cleaning calibration and other substrates that improves the correlation of measurements from calibration and product substrates and increases the useful life of the calibration substrates is herein disclosed. By exposing a calibration substrate to ultraviolet light, a reaction is triggered that results in the cleaning of the contaminants from the calibration substrate. For instance, monatomic oxygen is introduced to contaminants on the surface of a calibration substrate to remove the contaminants without inducing modifications in the substrate itself. Through the cleaning process, the temperature of the calibration substrate may be controlled to limit adverse effects caused by the overheating of the calibration substrate.
