  • Publication number: 20230369371
    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.

  • Publication number: 20220285423
    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.

  • Patent number: 10461117
    Abstract: A method for manufacturing a semiconductor structure includes the following steps. A first carrier is adhered to a first surface of a wafer by a first temporary bonding layer. A second surface of the wafer facing away from the first carrier is etched to form at least one through hole and at least one trench, in which a conductive pad of the wafer is exposed through the through hole. An isolation layer is formed on the second surface of the wafer, a sidewall of the through hole, and a sidewall of the trench. A second carrier is adhered to the second surface of the wafer by a second temporary bonding layer, and thus the through hole and the trench are covered by the second carrier. The first carrier and the first temporary bonding layer are removed.
