  • Patent number: 7453148
    Abstract: The present invention provides a structure of elastic dielectric layers with certain through holes adjacent to the angle of a RDL of WLP to absorb the stress. The elastic dielectric layer is made from silicone based materials with specific range of CTE, elongation rate and hardness, which can improve the mechanical reliability of the structure during temperature cycling test. The CTE difference between the RDL and the elastic dielectric material still may cause the elastic dielectric layer crack; to solve this problem, The present invention further provides a structure of dielectric layers with certain open through holes adjacent to the curve portion of a RDL of WLP which can reduce the stress accumulated at area of the dielectric layer adjacent to the RDL/dielectric layer interface to solve the crack problem of the dielectric layer.

  • Publication number: 20080085572
    Abstract: The present invention discloses a semiconductor packaging method, comprises steps of back lapping a processed silicon wafer to a desired thickness. Then, the dice are separated from the processed and lapped wafer into a single die. Then, the dice are picked and placed on a tool, an active surface of the dice is attached on the tool. A molding is performed to mold the dice by molding material. The tool is then removed from the dice to form a small unit. The next step is to arrange a plurality of the small units on a carrier in a matrix from. Then, a build-up layer, a re-distribution layer are formed over the dice, followed by forming solder balls on the dice. Finally, the carrier is removed.
