Vacuum Chuck Wafer Holder
Jason
Introduction Spin coaters can spread thin and flat substrates onto wafers very evenly using centrifugal force. A vacuum chuck holds wafers using suction as the spin coater spins. Purpose To design a wafer holder for the CNSI clean room that can center wafers (3″ & 4″) onto the vacuum chuck. The wafers need to spin…
