Waferhandling Wetbench During solar cell manufacturing, the silicon wafer undergoes a variety of wet chemical processes, including saw damage etching, texturing, and edge isolation. The wafers are processed on multi-lane roll conveyors through the wet bench. The baumann Waferhandling Wetbench automates the loading and unloading of the multi-lane conveyors so processing can begin. The system employs a specially developed gripper technology which ensures high handling reliability, while minimizing wafer damage or breakage. The system incorporates a SCARA robot, allowing highly flexible loading procedures with maximum precision. During loading and unloading, process and quality controls can be implemented, such as a weighing station to control the etching rate, material defect detection, TTV, etc. The baumann Waferhandling Wetbench is designed using many standard components, leveraging their inherent reliability, while ensuring flexibility and short delivery times.
