Wafer reader
Staff -- Test & Measurement World, 8/1/2005
The In-Sight 1721 wafer ID reader tracks semiconductor wafers through the manufacturing process. Slimmer and faster than its predecessors, it still maintains mounting and functional compatibility with them. Cognex says the In-Sight 1721 reads wafer marks that have been affected by process effects such as CMP, edge beads, and copper metallization. Cognex, www.cognex.com.
