Abstract:
Some embodiments relate to a semiconductor device package, which includes a substrate with a contact pad. A non-solder ball is coupled to the contact pad at a contact pad interface surface. A layer of solder is disposed over an outer surface of the non-solder ball, and has an inner surface and an outer surface which are generally concentric with the outer surface of the non-solder ball. An intermediate layer separates the non-solder ball and the layer of solder. The intermediate layer is distinct in composition from both the non-solder ball and the layer of solder. Sidewalls of the layer of solder are curved or sphere-like and terminate at a planar surface, which is disposed at a maximum height of the layer of solder as measured from the contact pad interface surface.
Abstract:
A package structure including a semiconductor die, a warpage control layer, an insulating encapsulant and a redistribution layer is provided. The semiconductor die has an active surface and a backside surface opposite to the active surface. The warpage control layer is disposed on the backside surface of the semiconductor die, wherein the warpage control layer comprises a material having a Young's Modulus of 100 GPa or more. The insulating encapsulant is encapsulating the semiconductor die and the warpage control layer. The redistribution layer is located on the insulating encapsulant and over the active surface of the semiconductor die.

The present disclosure relates to a package-on-package structure providing mechanical strength and warpage control. In some embodiments, the package-on-package structure includes a first set of conductive elements coupling a first package component to a second package component. A first molding material is arranged on the first package component. The first molding material surrounds the first set of conductive elements and outer sidewalls of the second package component and has a top surface below a top surface of the second package component. The stacked integrated chip structure further includes a second set of conductive elements that couples the second package component to a third package component.

Abstract:
Structures and formation methods of a chip package are provided. The method includes forming multiple conductive structures over a carrier substrate and disposing a semiconductor die over the carrier substrate. The method also includes disposing a mold over the carrier substrate. The method further includes forming a protection layer between the mold and the carrier substrate to surround the semiconductor die and the conductive structures. In addition, the method includes removing the mold.
Abstract:
The described embodiments of mechanisms of forming a package on package (PoP) structure involve bonding with connectors with non-solder metal balls to a packaging substrate. The non-solder metal balls may include a solder coating layer. The connectors with non-solder metal balls can maintain substantially the shape of the connectors and control the height of the bonding structures between upper and lower packages. The connectors with non-solder metal balls are also less likely to result in bridging between connectors or disconnection (or cold joint) of bonded connectors. As a result, the pitch of the connectors with non-solder metal balls can be kept small.
