  • Patent number: 7276782
    Abstract: A package structure for a semiconductor is described. The advantages thereof are that it has a great structural strength and when being penetrated by light, it will not be influenced by external light and can condense the light. Therefore, it is not easily be deformed so that the yield and quality of package can be increased, and when packaging an LED chip, it easily meets the package requirements of an electronic chip. In addition, the substrate structure is cheaper than the prior art, because a double-layered substrate is employed to improve the strength, and the package structure is also preferred because an external frame device is additionally used for preventing interference by external light. The package structure for the semiconductor has a substrate, an external frame device and a polymer filler.

  • Publication number: 20050093010
    Abstract: Stacked metal sections serve as two leads of an IC package. In one embodiment, an IC chip is mounted on one section serving as the terminal for the bottom electrode of the chip, and the top electrode of the chip is wire-bonded to the other section serving as another terminal for the chip. The thin sheet metal permits narrower etched separation between the two metal sections. Stacking of two pre-etched thin sheet metals strengthens the substrate. The package is covered with glue to hold the two sections together. The stacked pre-etched metal sheets can serve as a common substrate for a matrix of IC packages, which can later be cut in two orthogonal directions to yield individual packages.
