  • Abstract
    We investigate the electric field (E) dependence of the breakdown of porous low-k dielectrics by measuring the changes in the failure time distribution resulting from the presence of line edge roughness. We show that the Weibull β increases with decreasing field, clearly demonstrating that dielectric breakdown does not exhibit 1/E or E-n characteristics.
