Abstract
Discussed generally herein are methods and devices including or providing an electromagnetic interference (EMI) shielding. A device can include substrate including electrical connection circuitry therein, ground circuitry on, or at least partially in the substrate, the ground circuitry at least partially exposed by a surface of the substrate, a die electrically connected to the connection circuitry and the ground circuitry, the die on the substrate, a conductive material on a die backside, and a conductive paste or one or more wires electrically connected to the ground circuitry and the conductive material.
