books.google.com.au - Continuing improvement of integrated circuits (ICs) critically depends on the use of nonconventional materials. Interconnect delay is already the most severe limiting factor in most advanced IC. This delay can be minimized by reducing the interconnect capacitance, which is determined by a combination...http://books.google.com.au/books/about/Low_Dielectric_Constant_Materials_III.html?id=9ApTAAAAMAAJ&utm_source=gb-gplus-shareLow-Dielectric Constant Materials III:
