Abstract:
1. A microelectronic substrate processing method comprising: providing microelectronic substrate processing chamber that is configured to perform a microelectronic fabrication process on at least one microelectronic substrate that is contained therein; supplying densified carbon dioxide to the microelectronic substrate processing chamber from a carbon dioxide supply system, the densified carbon dioxide being used to perform the microelectronic fabrication process on the microelectronic substrate that is contained in the microelectronic substrate processing chamber; and supplying detergent to the microelectronic substrate processing chamber from a detergent supply system, the detergent being used to perform the microelectronic fabrication process on the microelectronic substrate that is contained in the microelectronic substrate processing chamber; and providing an auxiliary vessel that is separate from the microelectronic substrate processing chamber; wherein supplying detergent comprises: reducing pressure in said microelectronic substrate processing chamber and said auxiliary vessel; then adding a detergent formulation to said auxiliary vessel; then increasing the pressure in said microelectronic substrate processing chamber so that densified carbon dioxide can be pumped therethrough to clean the at least one microelectronic substrate in said microelectronic substrate processing chamber; and then transferring said detergent formulation from said auxiliary vessel to said microelectronic substrate processing chamber to facilitate the cleaning of the at least one microelectronic substrate therein.
