<p>An apparatus and method for large area high speed atomic layer chemical vapor processing wherein continuous and alternating streams of reactive and inert gases are directed towards a co-axially mounted rotating cylindrical susceptor from a plurality of composite nozzles placed around the perimeter of the processing chamber. A flexible substrate is mounted on the cylindrical susceptor. In one embodiment, the process reactor has four composite injectors arranged substantially parallel to the axis of rotation of the cylindrical susceptor. In the other embodiment, the susceptor cross section is a polygon with a plurality of substrates mounted on its facets. The reactor can be operated to process multiple flexible or flat substrates with a single atomic layer precision as well as high-speed chemical vapor processing mode. The atomic layer chemical vapor processing system of the invention also has provisions to capture unused portion of injected reactive chemical precursors downstream.</p> |
