Abstract: A process for removing organic materials from semiconductor wafers and a process for chemical solvent drying of wafers. In the drying process, a wafer submerged in a bath having a lower aqueous layer and an upper organic layer is lifted from the lower aqueous layer up through the upper organic layer and removed from the bath.

Abstract: Provided is a process for removing organic materials from semiconductor wafers. The process involves the use of subambient deionized water with ozone absorbed into the water. The ozonated water flows over the wafers and the ozone oxidizes the organic materials from the wafers to insoluble gases. The ozonated water may be prepared in-situ by diffusing ozone into a tank containing wafers and subambient deionized water.Also provided is a tank for the treatment of semiconductor wafers with a fluid and a gas diffuser for diffusion of gases directly into fluids in a wafer treatment tank.

Abstract: An end effector for holding or carrying semiconductor wafers during wet processing is disclosed. The end effector holds a plurality wafers with only two points of contact intruding onto the front or back surface of the wafer, holding the wafer with substantially no movement during processing at a slight angle from vertical.
