Processing system and method for treating a substrate

摘要

A processing system and method for chemical oxide removal, wherein the processing system includes a process chamber having a lower chamber portion configured to chemically treat a substrate and an upper chamber portion configured to thermally treat the substrate, and a substrate lifting assembly configured to transport the substrate between the lower chamber portion and the upper chamber portion. The lower chamber portion includes a chemical treatment environment that provides a temperature controlled substrate holder for supporting the substrate for chemical treatment. The substrate is exposed to a gaseous chemistry, such as HF/NH₃, under controlled conditions including surface temperature and gas pressure. The upper chamber portion includes a thermal treatment environment that provides a heating assembly configured to elevate the temperature of the substrate.
