Abstract
There is provided a leadframe having a plurality of coplanar electrically conductive leads. At least one metallic guard is bonded to the leads with a dielectric layer disposed between the metallic guard and the leads. The metallic guard has good adhesion to a polymer molding resin such that when the leadframe structure is encased in a molding resin, delamination is minimized. By restricting delamination, the ingress of water and water soluble contaminants to an integrated circuit device is inhibited.
