SOI inverter delay is 7.4 ps at Vdd=1.5 V and L/sub gate/=100 nm. Inverter delays show 16% (fanout=1) and 8% Vdd(V) (fanout=4) improvement over comparable bulk CMOS. Scaling analysis for PD-SOI shows a reduced role for junction capacitance and an increased history effect for scaled devices, so that SOI has significantly diminished performance gain relative to bulk CMOS for 50 nm devices (0.1 /spl mu/m generation).","PeriodicalId":268624,"journal":{"name":"2000 Symposium on VLSI Technology.

The limit on Tox reduction with respect to gate leakage tolerance is considered by the concept of \"dynamic\" gate leakage in nano-scale MOSFET's. Tox scaling is also limited by transistor performance degradation due to the loss of inversion layer charge through gate leakage and the degradation of carrier mobility in the channel from increased scattering. All the three effects are investigated experimentally on CMOS devices with gate length down to 50 nm and gate Tox down to 12 A. The minimum Tox is proposed and the implications on voltage scaling, high-k gate dielectrics and low-temperature CMOS are discussed.","PeriodicalId":268624,"journal":{"name":"2000 Symposium on VLSI Technology.

Present reliability methodology stresses oxides with a low impedance voltage source.

A Current Limited Constant Voltage Stress simulates circuit stress well. Limiting the current during the breakdown event reduces the post-breakdown conduction.
