The RIVP is engineered for use with all Genmark vacuum robots, providing accurate, non-contact measurement of the eccentricity and the orientation of the substrate placement in vacuum environments.
The device can be arbitrarily placed inside the robot’s working envelope. The operations of the prealigner include measurement of the wafer displacement, calculation of the necessary compensation, and orientation of the notch (or the flat) to the desired angle.
The RIVP is designed for use in a wide range of applications regardless of the size, shape, transparency, and thickness of the substrates that are to be aligned. The prealigner can measure wafers with diameters ranging from 100 to 300mm and square substrates from 100 to 200mm.
