Patent ID: 7896974

Claim:
A method for performing a wafer cleaning process, comprising: providing a chamber, including, a first volume configured to overlie a wafer; a plate configured to support a wafer, the plate further configured to define a second volume directly below the wafer when the wafer is supported on the plate, the plate including fluid inlets and fluid outlets defined in a periphery of the plate and outside a portion of the plate defined to support the wafer, the fluid inlets and fluid outlets oriented to direct a fluid flow through the first volume in a set pattern; a support structure configured to support the plate, the support structure further configured to define a third volume directly below the plate; placing a wafer on the portion of the plate defined to support the wafer; pressurizing the first volume, the second volume, and the third volume, the pressurizing causing the first volume to have a higher pressure than the second volume, the pressurizing further causing the second volume to have a higher pressure than the third volume; and providing a fluid to the first volume through the fluid inlets and removing the fluid from the first volume through the fluid outlets such that the fluid flows through the first volume in the set pattern, the fluid being formulated to effect a wafer cleaning process.
