Abstract
Stress-induced void growth is modeled for the case of a void bounded by two neighbors by invoking the one-dimensional diffusion equation. The resultant equation is then convoluted with an exponential distribution for void spacing to generate the mean void size as a function of time. Volumetric strain, atomic diffusivity and activation energy are then extracted for a given metallization and passivation system by fitting measured mean void size data to the analytical curve.
