  • Publication number: 20230324283
    Abstract: An imaging spectroscopic ellipsometry apparatus and method configured to measure thin films with high spatial resolution. The apparatus includes a rotating compensator that enables to simultaneously collect both spectrometric ellipsometric data and ellipsometric imaging with the use of the same measurement beam of light. Collecting both data sets simultaneously increases the information content for analysis and affords a substantial increase in measurement performance.

  • Publication number: 20230057928
    Abstract: An imaging spectropolarimeter configured to examine targets with polarized light, in which orientation of light-polarizing components is judiciously chosen to be target-specific and which employ a three-camera optical detection system defining an optical detection axis with respect to which individual camera analyzers are oriented in a specifically-defined fashion. Programmable electronic circuitry is adapted to substantially simultaneously acquire polarimetric images of the target utilizing intensity information collected by the multi-pixel sensors of the optical detection system.

  • Patent number: 11499870
    Abstract: An imaging spectropolarimeter for examining targets with polarized light, the spectropolarimeter including a light source adapted to produce polarized light directed at a target. Embodiments also include a three-camera camera system defining a three-camera camera axis with a first camera unit comprising a first analyzer set at 0°, a lens and a first multi-pixel sensor, a second camera unit comprising a second analyzer set at 45°, a lens and a second multi-pixel sensor, and a third camera unit comprising a third analyzer set at 90°, a lens and a third multi-pixel sensor. At least two beam splitters adapted to direct a portion of polarized light reflected from the target to each of the first, second and third camera units. Preferred systems include a processor adapted to produce polarimetric images of the target utilizing intensity information collected by the multi-pixel sensors.

  • Patent number: 8319966
    Abstract: Metrology systems and methods that measure thin film thickness and or index of refraction of semiconductor wafers with at least one deposited or grown thin film layer. The present invention measures near normal incidence and grazing angle of incidence reflection (using reflected broadband UV, visible, and near infrared electromagnetic radiation) from a small region on a sample. Embodiments of the system selectively comprise a near-normal incidence spectrometer/ellipsometer, a high angle of incidence spectrometer/ellipsometer, or a combination of the two.
