| 20090250818 | VIA ELECTROMIGRATION IMPROVEMENT BY CHANGING THE VIA BOTTOM GEOMETRIC PROFILE - An integration approach to improve electromigration resistance in a semiconductor device is described. A via hole is formed in a stack that includes an upper dielectric layer, a middle TiN ARC, and a lower first metal layer and is filled with a conformal diffusion barrier layer and a second metal layer. A key feature is that the etch process can be selected to vary the shape and location of the via bottom. A round or partially rounded bottom is formed in the first metal layer to reduce mechanical stress near the diffusion barrier layer. On the other hand, a flat bottom which stops on or in the TiN ARC is selected when exposure of the first metal layer to subsequent processing steps is a primary concern. Electromigration resistance is found to be lower than for a via structure with a flat bottom formed in a first metal layer. | 10-08-2009 |

| 20090119432 | Starvation Prevention Scheme for a Fixed Priority PCE-Express Arbiter with Grant Counters using Arbitration Pools - Method and apparatus for arbitrating prioritized cycle streams in a manner that prevents starvation. High priority and low priority arbitration pools are employed for arbitrating multiple input cycle streams. Each cycle stream contains a stream of requests of a given type and associated priority. Under normal circumstances in which resource buffer availability for a destination device is not an issue, higher priority streams are provided grants over lower priority streams, with all streams receiving grants. However, when a resource buffer is not available for a lower priority stream, arbitration of high priority streams with available buffer resources are redirected to the low priority arbitration pool, resulting in generation of grant counts for both the higher and lower priority streams. When the resource buffer for the low priority stream becomes available and a corresponding request is arbitrated in the high priority arbitration pool, a grant for the request can be immediately made since grant counts for the stream already exist. | 05-07-2009 |
