Patent ID: 7638437

Claim:
An in-situ thin-film deposition method for depositing a thin layer as a resistive contact and barrier on a loaded wafer, which is performed in a thin-film deposition apparatus comprising a transfer chamber including a robot arm and a plurality of chambers installed as a cluster type on the transfer chamber, the method comprising: depositing a TiSi x layer on the wafer by supplying a first reactive gas containing Ti and a second reactive gas containing Si to a first chamber; and transferring the wafer to a second chamber using the transfer chamber and depositing a TiN layer on the TiSi x layer, wherein when the TiSi x layer is deposited using a plasma ALD process, continuously applying plasma to the first chamber by supplying power to the first chamber and continuously spraying the second reactive gas onto the wafer are performed at the same time, wherein during the continuous spraying of the second reactive gas, pulse-spraying the first reactive gas and purging the first reactive gas that is not absorbed on the wafer are repeated in several cycles until the TiSi x layer is deposited on the wafer.
