  • MULTILAYERED CIRCUIT BOARD AND SEMICONDUCTOR DEVICE
    Publication number: 20100025093
    Abstract: A multilayered circuit board of the present invention has a single-side laminated structure and does not include a core substrate having via-holes formed therethrough and vias for providing electrical connection through the via-holes. The multilayered circuit board includes a plurality of pairs of layers, each pair including a conductor circuit layer and an insulator layer, wherein a glass transition temperature of each insulator layer is 170° C. or higher, a coefficient of thermal expansion at the glass transition temperature or lower of each insulator layer is 35 ppm or less, and a modulus of elasticity of each insulator layer is 5 GPa or more.
