Abstract
An electrical device including a substrate, a dielectric layer supported by the substrate having at least one vertical post disposed within a via hole of the dielectric layer, and at least one electrically conductive vertical interconnect laterally offset from the post. The post is configured to impart a non-tensile state to a region of the electrical device underlying the post. The coefficient of thermal expansion (CTE) of the post may be configured to cooperate with the CTE of the dielectric layer to provide the non-tensile state, such as the dielectric layer having a CTE that is equal to or greater than a CTE of the post. The dielectric layer may have a CTE that is less than the CTE of the electrically conductive vertical interconnect, and may be arranged to provide a buffer to tensile forces imparted by the vertical interconnect.
