A rotating wafer scanner was designed and developed in order to determine its operational feasibility and advantages over a linear wafer scanner. The scanner was first designed to operate at atmosphere. Each of its constituent parts were independently tested and when the final system was evaluated a 0.2 mum detection limit was observed. The latter result prompted the design and development of a vacuum rotating wafer scanner. The data obtained during the design and evaluation of the constituent parts of the latter system showed that particle detection in a vacuum is feasible.Type
