Abstract:
A stabilizing nozzle for securing a spherical shaped semiconductor device, the nozzle comprising: an enclosure having a top surface, the top surface having a plurality of apertures formed therein; a pressurized fluid source; a plenum located inside the enclosure and having an input and a plurality of outputs wherein the plenum input is connected to the pressurized fluid source and each one of the plurality of outputs are connected to the apertures through a conduit; wherein one of the apertures is located in a central position, as compared with the other (peripheral) apertures, so that the central aperture is directed to expel fluid from the pressurized fluid source alone an axis to float the semiconductor device above the top surface and the peripheral apertures are directed to expel fluid from the pressurized fluid source towards the axis to maintain the semiconductor device above the central aperture; wherein the central aperture is larger in size than any of the peripheral apertures and the peripheral apertures form a concentric ring around the central aperture.
