Abstract :
The combination of low k dielectric material application and aggressive scaling in advanced interconnects creates new challenges for thermal and electromigration solutions. The complexity and difficulty are discussed for modeling and evaluating thermal and EM interactions in circuit designs. A few examples are given to show quantitatively the impact of different dielectric materials on maximum allowed current density and scaling in Cu lines.
