  • 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.
