  • Patent number: 11264330
    Abstract: Disclosed are a chip package capable of improving the strength of a package and simplifying a manufacturing process and a manufacturing method therefor. This invention may improve the durability of the package by further forming a reinforcing layer on a chip by using an adhesive layer and molding the chip and the reinforcing layer so as to be integrated by using a molding layer. Also, the strength of the package may be improved by having a structure in which solder balls are formed between a base substrate and a re-wiring layer and integrated with the molding layer, and a wiring layer may be formed directly on the molding layer by using polyimide (PI) as the molding layer without using a separate insulating layer formed on the molding layer as in the conventional art.

  • Patent number: 7170170
    Abstract: The present invention discloses a bump for a semiconductor package, a semiconductor package applying the bump, and a method for fabricating the semiconductor package. As a second bump unit contacting an electrode terminal of a PCB has a smaller width than a first bump unit contacting an electrode pad of a semiconductor chip through a metal adhering layer, even if a pitch between the electrode pads of the semiconductor chip does not correspond to the pitch between the electrode terminals of the PCB, contact reliability is improved by the bump. In addition, the bump does not contact lines adjacent to the electrode terminal of the PCB, thereby preventing a mis-operation of the semiconductor package. Accordingly, the pitch between the electrode pads of the semiconductor chip and the pitch between the bumps can be minimized.
