    Abstract: A semiconductor package includes a semiconductor die including an active side, a redistribution layer over the active side of the semiconductor die, the redistribution layer including metal traces electrically connecting die pads on the active side of the semiconductor die to electrical contacts on an external surface of the semiconductor package, and a layered mold covering the semiconductor die opposite the redistribution layer. The layered mold includes a first resin layer adjacent to the redistribution layer, a fiber layer adjacent to the first resin layer and opposite the redistribution layer, and a second resin layer adjacent to the fiber layer and opposite the redistribution layer. A coefficient of thermal expansion (CTE) of the first resin layer is substantially different than a CTE of the second resin layer.

    Abstract: A semiconductor package has a relief recess in the mold compound, extending around the perimeter over the leads. The relief recess has a relief width greater than a thickness of the leads under the relief recess. Top surfaces of the leads may be exposed at the relief recess, or may be covered by the mold compound under the relief recess. In both cases, a height difference between the mold compound under the relief recess and the leads under the relief recess is less than the thickness of the leads under the relief recess. A majority of exposed side faces of the leads are characteristic of sawn surfaces, which includes leads being free of vertical striations or having burrs along bottom edges. The semiconductor package is singulated by sawing through the leads.

    Abstract: A wafer chip-scale package (WCSP) includes a substrate including a semiconductor surface layer including circuitry configured for at least one function having at least a top metal interconnect layer thereon that includes at least one bond pad coupled to a node in the circuitry. A redistribution layer (RDL) including a bump pad is coupled by a trace to metal filled plugs through a passivation layer to the bond pad. A solder ball is on the bump pad, and a dielectric ring is on the bump pad that has an inner area that is in physical contact with the solder ball.

    Abstract: In examples, a wafer chip scale package (WCSP) comprises a semiconductor die including a device side having circuitry formed therein. The WCSP includes a redistribution layer (RDL) including an insulation layer abutting the device side and a metal trace coupled to the device side and abutting the insulation layer. The WCSP includes a conductive member coupled to the metal trace, the conductive member in a first vertical plane that is positioned no farther than a quarter of a horizontal width of the semiconductor die from a vertical axis extending through a center of the semiconductor die. The WCSP includes a lead coupled to the conductive member and extending horizontally past a second vertical plane defined by a perimeter of the semiconductor die.
