  • Publication number: 20070257337
    Abstract: To provide a shield substrate, semiconductor package and semiconductor device which can give improved resistance to thermal stress. The shield substrate according to this invention is provided with a conductive film on which slits each having a shape through which electromagnetic wave noise does not leak are formed. These slits are rectangular slits formed in an array on the conductive film. In accordance with this configuration, the length of the straight line on the conductive film is interrupted by the slits, and thermal stress generated on the conductive film is interrupted by the slits. Thus, the thermal stress on the conductive film will not be excessively concentrated at one point, thereby preventing crack or flake-off from occurring on the conductive film.
