WAFER DETECTING APPARATUS |
摘要 |
A wafer detecting apparatus detects storage states of a plurality of wafers stored in a wafer container. The plurality of wafers are stored substantially horizontal in slots in the wafer container to be transferred in and out of a front opening of the wafer container. The wafer detecting apparatus includes a vertically extending illumination device that emits light through the front opening onto the plurality of wafers and an imaging device that receives the light reflected from the plurality of wafers. The imaging device is arranged substantially directly in front of the wafer container and the illumination device is arranged in at least one of left and right sides of the imaging device. |
