Abstract
An integrated circuit device has at least one environment-hardened die and at least one less-environment-hardened die. Environment-hardened circuitry on the environment-hardened die is more resistant to the degradation when exposed to a predetermined environmental condition than the less-environment-hardened circuitry on the environment-hardened die. The dice are combined using a 3D or 2.5D integrated circuit technology. This is very useful for testing circuits at adverse environmental conditions (e.g. high temperature), or for providing circuits to operate at such conditions.
