| Zusammenfassung: | A semiconductor wafer inspection system includes a camera and two or more illuminators. The illuminators illuminate a line of the semiconductor wafer in sequence and the camera captures an interleaved image of illuminated lines such that the individual images can be recovered from the interleaved image. The semiconductor wafer can be moved by a conveyor so that adjacent lines can be sequentially illuminated by the illuminators. The camera may include two or more line sensors. |
