发明名称 Method of increasing deposition rate of silicon dioxide on a catalyst
摘要 Methods for forming dielectric layers, and structures and devices resulting from such methods, and systems that incorporate the devices are provided. The invention provides an aluminum oxide/silicon oxide laminate film formed by sequentially exposing a substrate to an organoaluminum catalyst to form a monolayer over the surface, remote plasmas of oxygen and nitrogen to convert the organoaluminum layer to a porous aluminum oxide layer, and a silanol precursor to form a thick layer of silicon dioxide over the porous oxide layer. The process provides an increased rate of deposition of the silicon dioxide, with each cycle producing a thick layer of silicon dioxide of about 120 Å over the layer of porous aluminum oxide.
