WebMay 16, 2024 · A chuck mark looks like a circle of a different color that’s the same size as the spin chuck. Wafer Edge Effects The edges of wafers can cause problems for spin coating. Surface tension on the edge of the workpiece can cause a bead to form. As the bead spins, it creates a thicker layer on the outermost edge of the item to be covered. WebDec 10, 2004 · The compliant pin chuck was designed to address this concern and fabricated from silicon using lithography based microfabrication techniques. The chuck consists of an array of microflexure mechanisms that react to the presence of backside particles so as to minimize the nonplanarity caused otherwise. rawchefyin https://astcc.net
