  • Publication number: 20130299995
    Abstract: A semiconductor device has a substrate and insulating layer formed over a surface of the substrate. A first conductive layer is formed over the surface of the substrate. A second conductive layer is formed over an opposing surface of the substrate. A conductive via is formed through the substrate. An opening is formed in the insulating layer while leaving the first conductive layer intact. The opening narrows with a non-linear side or linear side. The opening can have a rectangular shape. A semiconductor die is mounted over the surface of the substrate. An underfill material is deposited between the semiconductor die and substrate. The opening in the insulating layer reduces a flow rate of the underfill material proximate to the opening. The flow rate of the underfill material proximate to the opening is substantially equal to a flow rate of the underfill material away from the opening.
