    摘要: A fabrication method of a semiconductor package structure includes: patterning a metal plate having first and second surfaces; forming a dielectric layer on the metal plate; forming a metal layer on the first surface and the dielectric layer; forming metal pads on the second surface, the metal layer having a die pad and traces each having a bond pad; mounting a semiconductor chip on the die pad, followed by connecting electrically the semiconductor chip to the bond pads through bonding wires; forming an encapsulant to cover the semiconductor chip and the metal layer; removing portions of the metal plate not covered by the metal pads so as to form metal pillars; and performing a singulation process. The fabrication method is characterized by disposing traces with bond pads close to the die pad to shorten the bonding wires and forming metal pillars protruding from the dielectric layer to avoid solder bridging.

    摘要: A semiconductor package structure includes: a dielectric layer; a metal layer disposed on the dielectric layer and having a die pad and traces, the traces each including a trace body, a bond pad extending to the periphery of the die pad, and an opposite trace end; metal pillars penetrating the dielectric layer with one ends thereof connecting to the die pad and the trace ends while the other ends thereof protruding from the dielectric layer; a semiconductor chip mounted on the die pad and electrically connected to the bond pads through bonding wires; and an encapsulant covering the semiconductor chip, the bonding wires, the metal layer, and the dielectric layer. The invention is characterized by disposing traces with bond pads close to the die pad to shorten bonding wires and forming metal pillars protruding from the dielectric layer to avoid solder bridging encountered in prior techniques.

    摘要: A method of manufacturing a quad flat non-leaded semiconductor package is provided. A metal plate is prepared and is defined with predetermined positions of a plurality of electrically conductive pads. A resist layer is formed on the metal plate, and a plurality of openings are formed in the resist layer and correspond to the predetermined positions of the electrically conductive pads. A solderable metal plated layer is formed in each of the openings of the resist layer. The resist layer on the metal plate is removed. A portion of the metal plate, which is not covered by the metal plated layers, is etched using the metal plated layers as a mask. A chip is mounted on the metal plate and is electrically connected to the electrically conductive pads. A molding process is performed such that the chip and the metal plate are encapsulated by an encapsulant.
