Abstract:
1. A processing chamber for processing semiconductor substrates, said processing includes at least post-wet-processing removal of drying fluid (DF) from at least one substrate using supercritical CO2, comprising: a chamber wall surrounding a processing volume of the processing chamber; a plenum extending only vertically between a lower end and an upper end, the plenum defining the chamber wall for the processing chamber, the plenum having an interior channel between the lower end and the upper end, the plenum having a supply connection to the supercritical CO2 at the lower end of the plenum; a set of manifolds coupled to said plenum, the set of manifolds arranged in rows, wherein each row is spaced apart from another row along the chamber wall, and each row is disposed at a distinct vertical position along the chamber wall, and each of the set of manifolds having a horizontal manifold connection to the interior channel of the plenum; a set of nozzles, each nozzle being coupled to one of the horizontal manifolds and each nozzle having a nozzle output on an interior-facing surface of the plenum that is directed toward the processing volume of the processing chamber; wherein said nozzle outputs are disposed flush within the interior-facing surface of the plenum; wherein each of the nozzle outputs is oriented substantially perpendicular to said chamber wall.
