  • Patent number: 10446504
    Abstract: A chip package is provided. A first bonding structure is disposed on a first redistribution layer (RDL). A first chip includes a sensing region and a conductive pad that are adjacent to an active surface. The first chip is bonded onto the first RDL through the first bonding structure. The first bonding structure is disposed between the conductive pad and the first RDL. A molding layer covers the first RDL and surrounds the first chip. A second RDL is disposed on the molding layer and the first chip and is electrically connected to the first RDL. A second chip is stacked on a non-active surface of the first chip and is electrically connected to the first chip through the second RDL, the first RDL, and the first bonding structure. A method of forming the chip package is also provided.

  • Patent number: 9548265
    Abstract: A chip package includes a chip, an isolation layer, and a redistribution layer. The chip has a substrate, an electrical pad, and a protection layer. The substrate has a first surface and a second surface. The substrate has a through hole, and protection layer has a concave hole, such that the electrical pad is exposed through the concave hole and the through hole. The isolation layer is located on the second surface, the sidewall of the through hole, and the sidewall of the concave hole. The redistribution layer includes a connection portion and a passive element portion. The connection portion is located on isolation layer and in electrical contact with the electrical pad. The passive element portion is located on isolation layer that is on second surface, and an end of passive element portion is connected to connection portion that is on the second surface.

  • Publication number: 20160315048
    Abstract: A semiconductor electroplating system includes a conducting ring and at least one conductive device. The conducting ring is used for carrying a wafer. The conducting ring has at least two connecting points. The wafer has a first surface and an opposite second surface. An isolation layer is located on the second surface. Two ends of the conductive device are respectively connected to the two connecting points of the conducting ring. When the conducting ring is immersed in the plating solution and is energized, a redistribution layer that is to be patterned is formed on the isolation layer. The conductive device is used for transmitting a partial current that passes through one of the connecting points to the other connecting point.
