1. A method of manufacturing a semiconductor device, comprising:
providing a substrate comprising:
a first side;
a second side opposite to the first side;
a conductive structure comprising a substrate inward terminal at the first side and a substrate outward terminal at the second side, and
a dielectric structure comprising a first dielectric comprising a first opening at the second side;
wherein:
the substrate outward terminal comprises:
a multi-stage terminal comprising:
 a pad base within the first opening comprising a pad base top side recessed below an upper surface the first dielectric and a pad base bottom side opposite the pad base top side;
 a pad head coupled to the pad base within the first opening, the pad head comprising a pad head top side and a pad head bottom side that is coupled to the pad base top side within the first opening;
 the pad head top side external to the first opening; and
 the pad base and the pad head are separate and distinct structures;
providing a semiconductor component at the first side of the substrate and electrically coupled to the substrate inward terminal; and
providing an encapsulant encapsulating the semiconductor component.
