Abstract
Systems, methods and apparatus related to pre-wetting an edge portion of a bonded wafer prior to wetting a flat, horizontal portion of the bonded wafer. The apparatus includes a frame having nozzles directed such that couplant discharged from these nozzles wet the edge of the wafer. The edge nozzles have couplant flow vectors that interface to dampen the trajectory of fluid to reduce splash and pre-wet the edges of the bonded wafer.
