    摘要: A plasma-enhanced chemical vapor deposition system includes a number of process gas injection tubes and at least one dedicated clean gas injection tube. A plasma is used to periodically clean the interior surfaces of the deposition chamber. The cleaning is made more rapid and effective by introducing the clean gas through the dedicated clean gas injection tube. In this manner the clean gas can be introduced at a relatively high flow rate without detracting from the cleaning of the interior surfaces of the process gas injection tubes. As a separate aspect of this invention, a high-frequency signal is applied to both terminals of the coil during the cleaning process. This produces a plasma, mainly by capacitive coupling, which has a shape and uniformity that are well-suited to cleaning the surfaces of the deposition chamber.

    摘要: A radical source for supplying radicals during atomic layer deposition semiconductor processing operations is provided. The radical source may include a remote volume, a baffle volume, and a baffle that partitions the remote volume from the baffle volume. The baffle volume and the remote volume may be fluidly connected through the baffle via a plurality of baffle holes. The baffle may be offset from a faceplate with a plurality of first gas distribution holes fluidly connected with the baffle volume. A baffle gas inlet may be fluidly connected with the baffle volume, and a first process gas inlet may be fluidly connected with the remote volume. Baffle gas may be flowed into the baffle volume to prevent radicalized first process gas in the remote volume from flowing through the baffle volume and the faceplate.
