Olejar Books

Continuing the spirit of the previous workshops, the proceedings contain new research results and advances in basic understanding of stress-induced phenomena in metallization. The current technology drive to implement low dielectric constant materials into copper metallization has brought new and significant challenges in process integration and reliability. Stresses arising in metallizations and surrounding dielectric structures due to thermal mismatch, electromigration, microstructure changes or process integration can lead to damage and failure of interconnect structures. Understanding stress-related phenomena in new materials and structures becomes critical for reliability improvement and metallization development. This is reflected in the papers included in the proceedings, which report results on electromigration, thermal stresses and void formation in copper-low k interconnect structures. The book also includes new results on fracture of low k dielectric structures, an important research area for reliability and integration of copper metallization.
