Abstract
A package-on-package structure includes a first package, a second package and first intermetallic features. The first package includes at least one semiconductor die, an insulating encapsulant, a redistribution layer and conductive pads. The insulating encapsulant is encapsulating the semiconductor die. The redistribution layer is disposed on the insulating encapsulant. The conductive pads are located at a surface of the insulating encapsulant. The second package is stacked on the first package and electrically connected to the conductive pads through connectors. The first intermetallic features are sandwiched in between the conductive pads and the connectors and have a control region and a growth region. The connectors are connected to the control region, and the growth region spreads out from a periphery of the control region such that the spreading of the growth region extends away from the conductive pads in a direction towards the semiconductor die.
