Abstract
A multi-layer substrate with metal layers as a moisture diffusion barrier for reduced electrical performance degradation over time after moisture exposure and methods of design and manufacture. The method includes determining a diffusion rate of an insulator material provided between an upper metal layer and an underlying signal line. The method further includes calculating a diffusion distance between a plane opening of the upper metal layer and the underlying signal line using the diffusion rate of the insulator material.
