Abstract

The radiation shielded and packaged integrated circuit semiconductor device includes a lid secured to a base to enclose the integrated circuit die within, wherein the lid and the base are each constructed from a high-Z material to prevent radiation from penetrating therethrough. Another embodiment includes a die attach slug constructed from a high-Z material disposed between the integrated circuit die and a base, in combination with a high-Z material lid to substantially block incident radiation.
