Abstract :
In high-speed advanced IC, performances of on-chip interconnects decrease due to crosstalk. Improvements thanks to copper metallization and new generations of low and ultra-low-k dielectrics are quantified in this paper. Based on a rigorous electromagnetic approach, electrical models of coupled lines are extracted and simulation procedures are experimentally verified. Both resulted in electrical critical parameters comparison for several interconnect generations.
