    Abstract: Chip packages and methods for forming the same are provided. The method includes providing a substrate having a chip region and a scribe-line region surrounding the chip region and forming a dielectric layer on an upper surface of the substrate. A dummy structure is formed in the dielectric layer over the scribe-line region of the substrate and extends along edges of the chip region. The dummy structure includes a first stack of dummy metal layers and a second stack of dummy metal layers arranged concentrically from the inside to the outside. The method also includes performing a sawing process on a portion of the dielectric layer that surrounds the dummy structure, so as to form a saw opening through the dielectric layer. At least the first stack of dummy metal layers remains in the dielectric layer after the sawing process is performed.

    Abstract: Chip packages and methods for forming the same are provided. The method includes providing a substrate having upper and lower surfaces, and having a chip region and a scribe-line region surrounding the chip region. The substrate has a dielectric layer on its upper surface. A masking layer is formed over the substrate to cover the dielectric layer. The masking layer has a first opening exposing the dielectric layer and extending in the extending direction of the scribe-line region to surround the chip region. An etching process is performed on the dielectric layer directly below the first opening, to form a second opening that is in the dielectric layer directly below the first opening. The masking layer is removed to expose the dielectric layer having the second opening. A dicing process is performed on the substrate through the second opening.

    Abstract: A chip package includes a first chip, a second chip, a first molding compound, and a first distribution line. The second chip vertically or laterally overlaps the first chip. The second chip has a conductive pad. The first molding compound covers the first and second chips, and surrounds the second chip. The first molding compound has a first through hole. The conductive pad is in the first through hole. The first distribution line is located on a surface of the first molding compound facing away from the second chip, and electrically connects the conductive pad in the first through hole.
