  • Patent number: 9646946
    Abstract: Fan-out wafer-level packaging (WLP) using metal foil lamination is provided. An example wafer-level package incorporates a metal foil, such as copper (Cu), to relocate bonding pads in lieu of a conventional deposited or plated RDL. A polymer such as an epoxy layer adheres the metal foil to the package creating conductive contacts between the metal foil and metal pillars of a die. The metal foil may be patterned at different stages of a fabrication process. An example wafer-level package with metal foil provides relatively inexpensive electroplating-free traces that replace expensive RDL processes. Example techniques can reduce interfacial stress at fan-out areas to enhance package reliability, and enable smaller chips to be used. The metal foil provides improved fidelity of high frequency signals. The metal foil can be bonded to metallic pillar bumps before molding, resulting in less impact on the mold material.

    Abstract: A transfer-bonding method for light emitting devices including following steps is provided. A plurality of light emitting devices is formed over a first substrate and is arranged in array, wherein each of the light emitting devices includes a device layer and an interlayer sandwiched between the device layer and the first substrate. A protective layer is formed over the first substrate to selectively cover parts of the light emitting devices, and other parts of the light emitting devices are uncovered by the protective layer. The device layers uncovered by the protective layer are bonded with a second substrate. The interlayers uncovered by the protective layer are removed, so that parts of the device layers uncovered by the protective layer are separated from the first substrate and are transfer-bonded to the second substrate.

  • Patent number: 9263274
    Abstract: In QFN packages for vehicles which are required to have high reliability, the side surface of leads is mostly covered with lead-to-lead resin protrusions, which prevent smooth formation of solder fillets during reflow mounting. When the lead-to-lead protrusions are mechanically removed using a punching die, there is a high possibility of causing cracks of the main body of the package or terminal deformation. When a spacing is provided between the punching die and the main body of the package in order to avoid such damages, a resin residue is produced to hinder complete removal of this lead-to-lead resin protrusion. The present invention provides a method for manufacturing semiconductor device of a QFN type package using multiple leadframes having a dam bar for tying external end portions of a plurality of leads.

  • Publication number: 20150147848
    Abstract: A resin-encapsulated semiconductor device is manufactured by mounting semiconductor elements on respective die pad portions of a frame. Electrodes on the surface of the semiconductor elements are wire bonded to lead portions of the frame. The die pad portions, semiconductor elements and lead portions are encapsulated with resin, leaving a bottom surface part of the lead portions exposed. The lead portions are partially cut by a rotary blade from an upper side of the resin to form concave parts in the lead portions, which are wet-etched to form exposed lead upper end parts. A plated layer is formed on the lead upper end parts and the lead bottom surface parts. The remaining parts of the lead portions with the plated layer are cut to separate the resin-encapsulated semiconductor device into individual pieces.

  • Patent number: 9040352
    Abstract: A semiconductor device package having a cavity formed using film-assisted molding techniques is provided. Through the use of such techniques the cavity can be formed in specific locations in the molded package, such as on top of a device die mounted on the package substrate or a lead frame. In order to overcome cavity wall angular limitations introduced by conformability issues associated with film-assisted molding, a gel reservoir feature is formed so that gel used to protect components in the cavity does not come in contact with a lid covering the cavity or the junction between the lid and the package attachment region. The gel reservoir is used in conjunction with a formed level setting feature that controls the height of gel in the cavity. Benefits include decreased volume of the cavity, thereby decreasing an amount of gel-fill needed and thus reducing production cost of the package.

  • Patent number: 9029197
    Abstract: To improve the reliability in applying a tape to the rear surface of a substrate while securing the heat resistance of the tape applied to the rear surface of the substrate. There is a gap between a bottom surface of a ditch provided in a support member and an upper surface of a driver IC chip. On the other hand, the upper surface side of a lead frame is supported by the support member so that the bottom surface of the ditch contacts the upper surface of a Low-MOS clip mounted over a Low-MOS chip. Thus, even in a state where the driver IC chip and the Low-MOS chip are mounted on the upper surface side of the lead frame, the tape can be reliably applied to the rear surface of the lead frame (in particular, to the rear surface of the product region).
