    • A chip package comprises a substrate with a composite capacitor/stiffener on the substrate. In one embodiment of the present invention, the substrate comprises a plurality of dielectric layers and a plurality of metallic layers interlaced with the dielectric layers. One of the metallic layers is on a surface of the substrate. Another dielectric layer is adhered onto the one metallic layer. A metallic plate is adhered onto the other dielectric layer, opposite the one metallic layer. The metallic plate is electrically connected to power or ground. The one metallic layer is electrically connected to ground or power, respectively, such that the metallic plate, the other dielectric layer and the one metallic layer form a capacitor. The one metallic layer is joined to a respective one of the plurality of dielectric layers in a same manner as another of the plurality of metallic layers is joined to another, respective one of the plurality of dielectric layers. Other embodiments of the composite capacitor/stiffener are also disclosed.
    • 芯片封装包括在衬底上具有复合电容器/加强件的衬底。 在本发明的一个实施例中,衬底包括多个电介质层和与电介质层交织的多个金属层。 金属层中的一个位于基板的表面上。 另一个电介质层粘附到一个金属层上。 金属板粘附在另一个电介质层上,与一个金属层相对。 金属板电连接到电源或接地。 一个金属层分别电连接到地或电源,使得金属板,另一个介电层和一个金属层形成电容器。 一个金属层以与多个金属层中的另一个金属层的另一个接合到多个电介质层中的相应一个电介质层的相同方式连接到多个电介质层中的相应一个。 还公开了复合电容器/加强件的其它实施例。
