NBTI product level reliability for a low-power SRAM technology

We present a methodology to investigate product level NBTI reliability for the 90 nm technology node including the correlation between transistor, circuit, and product level NBTI reliability. NBTI reliability lifetime, dielectric breakdown, and gate leakage currents pose an important limitation to the maximum applicable supply voltage across the gate oxide. Product standby currents and regulator design are highly influenced by transistor reliability. We will present product reliability data ensuring sufficient product level reliability as well as their correlation attempts to transistor level reliability data.
