This paper reports results of a study on copper voids seen in a back end of line (BEOL) module. The experiment was designed to study the effect of multiple parameters that can influence the occurrence of voids and their process margins. This work also reports the effect of changes in copper seed thickness on the product’s lifetime and reliability.
