摘要:
A source gas-supplying unit may include a chamber for receiving a liquid source. A first pipe may extend into the chamber to dip into the liquid source. The first pipe may provide a carrier gas to bubble through the liquid source to generate a vapor source. A second pipe may be connected to the chamber. The vapor source and the carrier gas may be supplied by the second pipe to a process chamber in which a semiconductor-manufacturing process may be carried out. A blocking structure may be provided in the sealed chamber. The blocking structure may block the liquid source that may be splashed toward the second pipe due to the bubbling.
摘要:
In a method of forming a layer, a titanium layer and a titanium nitride layer may be successively formed on a first wafer. By-products adhered to the inside of a chamber during the formation of the titanium nitride layer may be removed from the chamber. Processes of forming the titanium layer, forming the titanium nitride layer, and removing the by-products may be repeated relative to a second wafer.
