Abstract

A semiconductor structure is disclosed. The semiconductor structure includes an electrically conductive layer disposed over a substrate. A moisture barrier layer is disposed over the substrate and between the substrate and the electrically conductive layer. A dielectric layer is disposed over the moisture barrier layer. The dielectric layer has an elastic modulus that is lower than an elastic modulus of the moisture barrier layer.
