Abstract:
Apparatuses, systems, and methods for providing beams for controlling charges on a sample surface of charged particle beam system. In some embodiments, a module comprising a laser source configured to emit a beam. The beam may illuminate an area adjacent to a pixel on a wafer to indirectly heat the pixel to mitigate a cause of a direct photon-induced effect at the pixel. An electron beam tool configured to detect a defect in the pixel, wherein the defect is induced by the indirect heating of the pixel.
