Abstract
A semiconductor package device comprises a substrate, a first electronic component, a first encapsulant, a second electronic component, and a first conductive trace. The substrate has a first surface. The first electronic component is on the first surface of the substrate. The first encapsulant is on the first surface of the substrate and covers the first electronic component. The second electronic component is on the first encapsulant. The first conductive trace is within the first encapsulant. The first conductive trace is electrically connected to the second electronic component.
