Embodiments of the invention include a method for forming a copper interconnect having a bi-layer copper barrier layer. The method involves providing a substrate having an insulating layer with an opening therein configured to receive an inlaid conducting structure. A copper seed layer is formed on the insulating layer and in the opening. The seed layer is implanted with barrier material ions to form an implanted seed layer. Upon the implanted seed layer is formed a bulk copper-containing layer. The substrate is then annealed so that barrier material ions migrate through the seed layer to an interface between the seed layer and the insulating layer to form a final barrier layer. The barrier material can include palladium, chromium, tantalum, magnesium, and molybdenum.

Methods for forming robust copper structures include steps for providing a substrate with an insulating layer with openings formed therein. At least two barrier layers are then formed followed by the deposition of a copper seed layer which is annealed. Bulk copper deposition of copper and planarization can follow. In one approach the seed layer is implanted with suitable materials forming an implanted seed layer upon which a bulk layer of conductive material is formed and annealed to form a final barrier layer. In another approach, a barrier layer is formed between two seed layers which forms a base for bulk copper deposition. Another method involves forming a first barrier layer and forming a copper seed layer thereon. The seed layer being implanted with a barrier material (e. g. palladium, chromium, tantalum, magnesium, and molybdenum or other suitable materials) and then bulk deposition of copper-containing material is performed followed by annealing.

Embodiments of the invention include a method for forming a copper interconnect having a bi-layer copper barrier layer. The method comprises the steps of providing a substrate with a low-K dielectric insulating layer and an opening in the insulating layer. A first barrier layer of tantalum/tantalum nitride is formed on the insulating layer and in the opening. A second barrier layer consisting of a material selected from the group of palladium, chromium, tantalum, magnesium, and molybdenum is formed on the first barrier layer. A copper seed layer is formed on the second barrier layer and implanted with barrier ions and a bulk copper layer is formed on the seed layer. The substrate is annealed and subject to further processing which can include planarization.

A method and apparatus for determining information associated with a particular multicast channel in a multicast network are disclosed. In accordance with the method, a request message requesting information associated with the particular multicast channel is generated and sent to the multicast network. Further, the request message is propagated downstream in a recursive manner via a multicast topology of the multicast network. A response to the request message is propagated upstream via the multicast topology to generate a response message including requested information associated with the particular multicast channel. The information may comprise number of users receiving the particular multicast channel.

Methods and systems for reducing channel change startup delays for multicast digital video streams are described. Packets of a multicast digital video transport stream having a plurality of normal Group of Pictures are received. Further, a channel change request is received and a speed-up Group of Pictures is inserted in the stream in response to the channel change request. In one embodiment, video stream specific information is also inserted in the stream. The packets are processed and transmitted.

A method, apparatus, and article of manufacture for computer-implemented support of database indexes based on a generalized B-tree index. The index is stored in a B-tree on a data storage device connected to a computer. In particular, multiple key sources are processed using key transformation. Then, a plurality of key targets are generated based on the processed key sources.
