Abstract:
Integrated circuits are manufactured using a direct write lithography step to at least partially form at least one layer within the integrated circuit. The performance characteristics of an at least partially formed integrated circuit are measured and then the layout design to be applied with a direct write lithography step is varied in dependence upon those performance characteristics. Accordingly, the performance of an individual integrated circuit, wafer of integrated circuits or batch of wafers may be altered.
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.
