Chip level electromigration (EM) reliability is determined by: 1) the element level EM failure probability used for design guideline generation; and 2) the distribution of EM elements against design limits. Balancing these two factors is critical for

Understanding and managing both chip-to-package interaction (CPI) and solder bump electromigration (EM) in new designs is becoming an increasing challenge for flip chip plastic ball grid array (FCPBGA) packaging. Requirements for state-of-the-art dev

Stress-induced voids can form in Cu interconnects, due to either thermal expansion mismatch between the metal and the dielectric or due to confined grain growth in the Cu. The fail rate due to stress-induced voids increases as device dimensions decre

Reliability monitoring is an important part of process control in high-volume production. For metallization, a wafer-level electromigration (WL-EM) test is usually the method of choice to get a good indication of process variation. Different WL-EM me

In the past few years, copper has been widely used as interconnect metallization for advanced ultralarge-scale integration (ULSI) circuits. Due to the unique chemical properties of copper compared to its predecessor, aluminum, different integration p

Specific details of both fabrication process and geometry of Cu interconnects result in different electromigration (EM) fail modes. This paper discusses EM characteristics of line depletion stress, i.e., for the case of electrons flowing from a via a
