WebMarangoni Dryer . Wafers in a cassette are spun at high speeds. Water is removed by centrifugal force. A chamber with some liquid IPA is heated. Heat combined with a cooling coil causes the liquid IPA to form a cloud. Wafers exposed to this vapor cloud are dried. Wafers submerged in water are slowly passed through a thin layer of IPA liquid. ... WebJan 1, 2014 · Marangoni effects may play a major role during the formation and detachment of a drop or bubble, since the formation of such a drop naturally involves the formation of a new surface which needs to be covered by surfactant. In this situation, surfactant coverage of the new interface occurs gradually as it is formed, and the rate at which the new ...
