Abstract:
1. An apparatus for depositing seed layers over a substrate, the substrate includes a patterned insulating layer which comprises at least one opening surrounded by a field, the at least one opening having sidewalls and bottom surfaces and top corners, and the apparatus comprising: a CVD chamber adapted to deposit one or more CVD seed layers over the substrate; a PVD chamber adapted to deposit one or more PVD seed layers over the substrate; and a controller which includes recipe information, said recipe information includes deposition sequence and process parameters for operation of the deposition chambers, wherein the controller, in response to the recipe information, causes the CVD chamber to first deposit a continuous CVD seed layer over the substrate, and then causes the PVD chamber to deposit a PVD seed layer over the continuous CVD seed layer, wherein: (a) the continuous CVD seed layer is continuous over the sidewalls and bottom surfaces of the at least one opening, (b) the continuous CVD seed layer has a thickness from about 20 Å to about 250 Å over the field, and (c) the controller causes the stopping of the deposition of the seed layers so as to leave room for electroplating inside the at least one opening.
