Abstract:
An apparatus for processing a semiconductor wafer, comprising:a first pair of rollers configured for preparing the semiconductor wafer in a vertical orientation; a second pair of rollers configured for preparing the semiconductor wafer in a vertical orientation; a track configured to support the semiconductor wafer in the vertical orientation between the first pair of rollers and the second pair of rollers; and a pair of guiding rollers configured to transition the semiconductor wafer along the track from the first pair of rollers to the second pair of rollers, wherein each of the first pair of rollers and the second pair of rollers includes a first roller and a second roller, each first roller and second roller being oriented side by side and configured to rotate, an axis of rotation for each first and second roller being oriented parallel to a direction of movement along which the semiconductor wafer travels when transitioning along the track from the first pair of rollers to the second pair of rollers.
