SQL Performance Tuning

Technical leaders from around the world gather here to discuss developments in the areas of interconnect performance, advanced metallization, low-dielectric constant materials, barrier metallization, atomic layer deposition, advanced packaging and vertical integration. Both current state-of-the-art and ongoing challenges associated with multilevel interconnect are addressed. Included are papers on the latest developments in the integration of low-dielectric constant materials with copper-based metallization, and advances in the understanding of means by which process- or stress-induced damage can be mitigated and reliability of the interconnect system improved. Additional contributions discuss the design, development and modeling of advanced on-chip and multichip interconnect architectures and real-world implementation of optimized designs, materials and processes for production of leading-edge microelectronic devices.

Superconductors are entering a new age where they will be much more commonplace. High-temperature superconductors (HTS) are currently in the marketplace for rf filter applications and are coming into power applications as wires for cables, fault current limiters and motors/generators. Critical to enabling these developments are the great advances over the last decade-and-a-half in preparation of high-quality materials. Equally exciting, new superconductors are emerging and a better understanding of the cuprates is evolving. The three-year-old MgB2 superconductor appears to be now moving on to the applications arena as well. This book offers a diverse collection of timely presentations on these new frontiers in superconducting materials. Topics include: developments in second-generation HTS wire, known as coated conductors; progress in first-generation HTS wire towards better performance and manufacturing; MgB2 materials developments, especially thin films and wires; rf applications; a
