Abstract
Semiconductor devices and method of manufacture are provided. In embodiments a conductive connector is utilized to provide an electrical connection between a substrate and an overlying shield. The conductive connector is placed on the substrate and encapsulated with an encapsulant. Once encapsulated, an opening is formed through the encapsulant to expose a portion of the conductive connector. The shield is deposited through the encapsulant to make an electrical connection to the conductive connector.
