Abstract:
1. A gas manifold assembly for vapor deposition processes, comprising: a middle section containing a first gas inlet, a first gas manifold extending from the first gas inlet to a first plurality of passageways, and a tube extending along a central axis and containing a first channel along the central axis, the first plurality of passageways being disposed radially around the tube and in fluid communication with the first channel; a lower section coupled to the middle section and containing a second gas inlet, a second gas manifold extending from the second gas inlet to a second plurality of passageways, and an opening concentric with the central axis, wherein the tube extends to the opening to form a second channel between the tube and an edge of the opening and the second channel is concentric with the central axis, the second plurality of passageways being disposed radially around the tube and in fluid communication with the second channel, and wherein a first gas flow path extends from the first gas inlet, through the first gas manifold of the middle section, through the first plurality of passageways and through the first channel of the tube and a second gas flow path extends from the second gas inlet, through the second gas manifold of the lower section, through the second plurality of passageways and through the second channel, wherein the first flow path is contained in the middle and lower sections and the second flow path is contained in the lower section; and an upper section coupled to the middle section.
