Abstract
A semiconductor article processor sprays processing chemicals on a semiconductor article or wafer within a chamber. A door with an inflatable resilient seal, seals the chamber closed during processing. A seal support on the door extends radially outwardly into the inflatable seal, to better hold the seal onto the door. Inflation pressures can be increased, and the accumulation of chemical residues around the inflatable seal are decreased. Consequently, the effectiveness and reliability of the inflatable seal is improved.
