Paper Abstract

This paper describes the effects of grazing angle illumination on the particle sensitivity for small particles resting on bare silicon wafers and on patterned wafers. A mathematical model of particle illumination is used to support data gathered from the Inspex EX2000 Patterned Wafer Inspection System. A methodology is given for setting up the instrument in order to achieve maximum particle sensitivity on patterned wafers.
