    Abstract: A package substrate may include an insulating substrate, a circuit pattern and a mold gate pattern. The insulating pattern may have a mold gate region through which a molding member may pass. The circuit pattern may be formed on the insulating substrate. The mold gate pattern may be formed on the mold gate region of the insulating substrate. The mold gate pattern may include a polymer having relatively strong adhesion strength with respect to the insulating substrate and relatively weak adhesion strength with respect to the molding member. Thus, costs of the package substrate and the semiconductor package may be decreased.

  • Patent number: 7645643
    Abstract: A reliable optical semiconductor device can include an optical semiconductor chip sealed in a surrounding soft resin and in a hard resin that is harder than the soft resin. The hard resin can include an aperture that is configured to relieve a state of hermetic sealing for the soft resin (allows the soft resin to expand during volume change due to temperature fluctuations, etc.) and can be formed in a direction that imposes substantially no optical influence on a function of the optical semiconductor chip. The soft resin and the hard resin can be employed for double sealing to form the highly reliable optical semiconductor device without requiring additional space. This is effective to solve a problem caused in a conventional optical semiconductor device associated with double sealing by soft and hard resins, which requires a space between both resins and results in deteriorated performance, for example, a reduced amount of light.

    Abstract: A conductive region electrically connected to a buffer coat film is formed on at least one corner of a semiconductor substrate, so that electricity charged on a package seal resin or a surface of the buffer coat film is allowed to flow toward the conductive region through a conductive path. Thus, density of the electricity charged on the package seal resin or the surface of the buffer coat film is lowered, and electric discharge can be suppressed. Since the electric discharge is suppressed, no high voltage is applied to an external input/output terminal. As a result, it is possible to prevent a circuit metal wire connected to an integrated circuit from being fused and an interlayer insulating film from being damaged.

  • Patent number: 7602054
    Abstract: In one embodiment, a method for forming a molded flat pack style package includes attaching electronic chips to an array lead frame, which includes a plurality of elongated flag portions with tab portions and a plurality of leads. The method further includes connecting the electronic chips to specific leads, and then molding the array lead frame while leaving portions of the leads exposed to form a molded array structure. The molded array structure is then separated to provide molded flat pack style packages having exposed leads for insertion mount and exposed tab portions. In an alternative embodiment, the separation step produces a no-lead configuration with exposed tab portions.

  • Patent number: 7598123
    Abstract: A semiconductor component comprising two stacked semiconductor dice and a method of manufacture. A leadframe having an active area that includes leadframe leads and a cavity is mounted to a support material such as an adhesive tape. A packaged semiconductor die that includes a first semiconductor die mounted to a support structure and encapsulated within a mold compound is mounted on the adhesive tape. A second semiconductor die is mounted to the packaged semiconductor die. Bond pads on the second semiconductor die are electrically connected to the leadframe, the support structure on which the first semiconductor die is mounted, or both. A mold compound is formed around the second semiconductor die, portions of the leadframe, and the packaged semiconductor die. The adhesive tape is removed and the leadframe is singulated to form multi-chip packages.

  • Publication number: 20090243064
    Abstract: A method of manufacturing a semiconductor package involves providing a substrate having a window. The substrate may include a leadframe having half-etched leads. First and second semiconductor devices are mounted to a top surface of the substrate on either side of the window using an adhesive. A third semiconductor device is mounted to the first and second semiconductor devices using an adhesive. The third semiconductor device is disposed over the window of the substrate. A wirebond or other electrical interconnect is formed between the third semiconductor device and a contact pad formed over a bottom surface of the substrate opposite the top surface of the substrate. The wirebond or other electrical interconnect passes through the window of the substrate. An encapsulant is deposited over the first, second, and third semiconductor devices.

  • Publication number: 20090242912
    Abstract: A method comprises forming elongate structures (5) on a first substrate (3), such that the material composition of each elongate structure (7) varies along its length so as to define first and second physically different sections in the elongate structures. First and second physically different devices (1,2) are then defined in the elongate structures. Alternatively, the first and second physically different sections may be defined in the elongate structures after they have been fabricated. The elongate structures may be encapsulated and transferred to a second substrate (7). The invention provides an improved method for the formation of a circuit structure that requires first and second physically different devices (1,2) to be provided on a common substrate. In particular, only one transfer step is necessary.
