  • Patent number: 8102521
    Abstract: An inspection system includes optics, an object support for mounting an object in a region of an object plane of the optics, a bright-field light source, and a dark-field light source. The inspection system also includes an image detector having a radiation sensitive substrate disposed in a region of an image plane of the optics and a beam dump.
    Type: Grant

  • Patent number: 8072591
    Abstract: A wafer inspection system has a bright field imaging beam path and a dark field imaging beam path to obtain bright field images and dark field images of a full 300 mm wafer. The optical system provides for telecentric imaging and has low optical aberrations. The bright field and dark field beam paths are folded such that the system can be integrated to occupy a low volume with a small foot print.

  • Publication number: 20110043796
    Abstract: An inspection system includes imaging optics for imaging an object plane into an image plane. The imaging optics include an objective lens having positive optical power, a first lens group having negative optical power, and a second lens group having positive optical power. The optical elements are arranged along a common optical axis with a pupil plane of the imaging optics located between the first lens group and the second lens group.

  • Patent number: 7064828
    Abstract: A metrology device, such as an ellipsometer, includes a light source that produces a pulsed electromagnetic beam, such as a flash bulb or pulsed laser, and a spatially dependent polarizing element that introduces a spatially dependent retardation in the light beam. The use of a pulsed light source is advantageous over a continuous light source, as a pulsed light source generates less heat, is stronger, lasts longer, and does not need the use of a mechanical shutter. The use of a spatially dependent polarizing element advantageously eliminates the use of temporally dependent moving polarization modulation elements, thereby allowing the use of a pulsed light source. Downstream of the spatially dependent polarizing element are the analyzer and a multi-element detector that may be synchronized with the pulsed electromagnetic beam to detect after one or several pulses of light have been emitted from the pulsed light source.
