Abstract:
A scanned optical system for use in optical probing applications provides a large Field of View (FOV) for objective lenses having high Numerical Aperture (NA), such as Solid Immersion Lenses (SIL's). This enables high resolution imaging of semiconductor devices for such applications as laser probing, TIVA/LIVA, OBIRCH, and photon emission timing analysis. A hybrid scanning optics configuration is disclosed to provide high resolution imaging over a small area along with low resolution imaging over a large area.
