Abstract:
1. A method of processing a film stack containing one or more silicon-containing layers and one or more metal-containing layers on a substrate in a substrate processing system, comprising: depositing the one or more silicon-containing layers on the substrate in a chemical vapor deposition process chamber of the substrate processing system; transferring the substrate from the chemical vapor deposition process chamber into a first transfer chamber maintained at a vacuum level equal to a vacuum level of the chemical vapor deposition process chamber; transferring the substrate from the first transfer chamber to a second transfer chamber without breaking vacuum; transferring the substrate from the second transfer chamber to a physical vapor deposition process chamber, the second transfer chamber and the physical vapor deposition process chamber maintained at the same vacuum level, the vacuum level of the physical vapor deposition process chamber is different than the vacuum level of the chemical vapor deposition process chamber; and depositing the one or more metal-containing layers on the surface of the silicon-containing layers in the physical vapor deposition process chamber without any surface treatment of the one or more silicon-containing layers.
