Reliable CMOS VLSI Design Considering Gate Oxide Breakdown
نویسنده
چکیده
As technology scales down into the nanometer region, the reliability mechanism caused by time dependent dielectric breakdown (TDDB) has become one of the major reliability concerns. TDDB can lead to performance degradation or logic failures in nanoscale CMOS devices, and can cause significant increase of leakage power in the standby mode. In this paper, the TDDB effects on the delay and power of the nanoscale CMOS circuits are analyzed using ISCAS85 benchmark circuits that are designed using a 45-nm CMOS predictive technology model. Based on the TDDB analysis, a reliable CMOS VLSI design methodology using a redundancy system has been proposed. Keywords-TDDB; Reliability; Gate oxide breakdown; Time dependent dielectric breakdown; Aging effect

The gate oxide thickness, (tox), of Complementary Metal Oxide Semiconductor (CMOS) processes has been steadily been thinning as a result of technology trends. To keep the switching power dissipation of integrated circuits at bay, successive technology generations have relied on reducing the supply voltage. In order to maintain performance, and control short channel effects, however, a reduction...
