Abstract:
1. A method of cleaning a semiconductor structure in a substantially enclosed treatment vessel, comprising: installing a fail-shut valve in the substantially enclosed treatment vessel for removal of liquids therefrom; substantially filling the substantially enclosed treatment vessel with a gas inert to the semiconductor structure for creating an atmosphere of inert gas inside the substantially enclosed treatment vessel; positioning a semiconductor structure within the substantially enclosed treatment vessel; rinsing the semiconductor structure with DI water in the atmosphere of inert gas within the substantially enclosed treatment vessel; submerging the semiconductor structure in a DI water bath in the substantially enclosed treatment vessel, the DI water bath having a surface with the atmosphere of inert gas; forming a substantially continuous layer of a drying liquid upon the surface of the DI water bath, the substantially continuous layer of drying liquid forming a drying liquid-DI water interface; and displacing the DI water bath through the fail-shut valve by feeding additional inert gas into the substantially enclosed treatment vessel such that the substantially continuous layer of drying liquid substantially wipes down the semiconductor structure.
