Abstract:

A semiconductor wafer mapping apparatus comprising a frame forming a wafer load opening communicating with a load station for a substrate carrier disposed to hold more than one wafers vertically distributed in the substrate carrier for loading through the wafer load opening, a movable arm movably mounted to the frame so as to move relative to the wafer load opening and having at least one end effector movably mounted to the movable arm to load wafers from the substrate carrier through the wafer load opening, an image acquisition system including an array of cameras arranged on a common support and each camera fixed with respect to the common support that is static with respect to each camera of the array of cameras, wherein each respective camera is positioned with a field of view disposed to view through the wafer load opening with the common support positioned by the movable arm.
