Abstract:
1. A system for defect detection and photoluminescence measurement of a sample, comprising: a radiation source configured to target radiation to the sample; an optics assembly positioned above the sample to receive a sample radiation, the sample radiation being radiation which is at least one of reflected by, scattered by, or radiated from the sample, the optics assembly configured to collect the sample radiation; a filter module configured to receive the sample radiation collected by the optics assembly, the filter module separating the sample radiation collected by the optics assembly into a first radiation portion and a second radiation portion; a defect detection module configured to receive the first radiation portion from the filter module, the defect detection module configured to detect at least one defect of the sample utilizing the first radiation portion; and a photoluminescence measurement module configured to receive the second radiation portion from the filter module, the photoluminescence measurement module including a spectrometer configured to detect a local photoluminescence spectrum of the sample utilizing the second radiation portion, the photoluminescence measurement module configured to provide a photoluminescence mapping based upon the detected local photoluminescence spectrum, the defect detection module and the photoluminescence measurement module configured to receive the respective first radiation portion and the second radiation portion substantially simultaneously.
