Beschreibung
Zusammenfassung:	A method and an apparatus for manufacturing a semiconductor device are provided capable of making a barrier metal layer having a thin film and providing a sufficient barrier property with a low manufacturing cost. The method includes forming a barrier metal layer 5 on predetermined positions on a Cu wiring layer 3 formed on a semiconductor substrate by a CVD method or an ALD method, and forming an Al layer 6 on the barrier metal layer 5 without exposing it to the atmosphere.
