Abstract:
A package-on-package structure including a first and second package is provided. The first package includes a first semiconductor die, a plurality of conductive pins, an insulating encapsulant, a backside connection structure and a redistribution layer. The conductive pins are surrounding the first semiconductor die and have a base portion with a first width and a body portion with a second width, the base portion is connected to the body portion and the first width being larger than the second width. The insulating encapsulant is encapsulating the first semiconductor die and the conductive pins. The backside connection structure is disposed on the first semiconductor die and electrically connected to the conductive pins. The redistribution layer is disposed on the first semiconductor die, and electrically connected to the first semiconductor die and the conductive pins. The second package is stacked on the first package and electrically connected to the backside connection structure.

Claim (Index 14):
A method of manufacturing a package-on-package structure, comprising:\n forming a first package, comprising:\n providing a carrier; \n bonding a backside connection structure on the carrier, wherein the backside connection structure comprises a first connection layer exposed on a first surface of the backside connection structure, and a second connection layer exposed on a second surface of the backside connection structure, the second surface is facing the carrier and is opposite to the first surface; \n disposing a plurality of conductive pins on the first surface of the backside connection structure, the plurality of conductive pins is electrically connected to the first connection layer of the backside connection structure, and each of the plurality of conductive pins has a base portion with a first width and a body portion with a second width, the base portion is connected to the body portion and the first width being larger than the second width; \n disposing a first semiconductor die on the first surface of the backside connection structure through an adhesive layer, wherein the first semiconductor die is surrounded by the plurality of conductive pins and the adhesive layer is sandwiched between the first semiconductor die and the first surface of the backside connection structure; \n forming an insulating encapsulant on the backside connection structure encapsulating the first semiconductor die and the plurality of conductive pins; \n forming a redistribution layer on the insulating encapsulant, wherein the redistribution layer is electrically connected to the plurality of conductive pins and the first semiconductor die; and \n de-bonding the carrier to reveal the second connection layer exposed on the second surface of the backside connection structure; \n stacking a second package on the first package, wherein the second package is electrically connected to the second connection layer of the backside connection structure through a plurality of conductive balls.
