发明名称 DEVICE AND METHOD FOR INSPECTING MOVING SEMICONDUCTOR WAFERS
摘要 <p>DEVICE AND METHOD FOR INSPECTING MOVING SEMICONDUCTOR WAFERS Device for inspecting defects in semiconductor wafers, comprising a member for detecting surface defects using variations in the slope of a surface of the wafer, a member for detecting surface defects using variations in the light intensity reflected by a surface of the wafer, at a plurality of points, a member for detecting light intensity scattered by the surface of the wafer, a light source, and a detecting and classifying mechanism connected upstream of said detecting members.
