Packaged semiconductor devices and packaging methods |
摘要 |
Packaged semiconductor devices and packaging methods are disclosed. In some embodiments, a packaged semiconductor device includes an integrated circuit die and through-vias disposed in a molding compound. A first redistribution layer (RDL) is disposed over a first side of the through-vias, the integrated circuit die, and the molding compound. A second RDL is disposed over a second side of the through-vias, the integrated circuit die, and the molding compound. Contact pads are disposed over the second RDL. An insulating material of the second RDL includes a recess around a perimeter of one of the contact pads. |
