چکیده

Deuterated oxides exhibit prolonged hot carrier lifetimes at room temperature. We report evidence that this improved hot carrier hardness exists over the temperature range between -25 °C and 200 °C. However, the benefit of deuterium incorporation deceases with increasing stress temperature. Furthermore the VT -shift shows a remarkable absence of temperature dependence for the deuterated samples. The results are compared to the existing vibration-relaxation model.

Temperature Dependence of Hot-Carrier-Induced Degradation in 0.1 m SOI nMOSFETs With Thin Oxide

This letter investigates hot-carrier-induced degradation on 0.1 m partially depleted silicon-on-insulator (SOI) nMOSFETs at various ambient temperatures. The thermal impact on device degradation was investigated with respect to body-contact nMOSFETs (BC-SOI) and floating-body SOI nMOSFETs (FB-SOI). Experimental results show that hot-carrier-induced degradation on drive capacity of FB-SOI device...

Low-frequency noise in hot-carrier degraded nMOSFETs

This paper discusses the low-frequency (LF) noise in submicron nMOSFETs under controlled transistor aging by hot-carrier stress. Both traditional, steady-state LF noise as well as the LF noise under periodic large-signal excitation were found to increase upon device degradation, for both hydrogen passivated and deuterium passivated Si–SiO2 interfaces. As hot-carrier degradation is slower in deu...

Hot-carrier reliability evaluation for CMOS devices and circuits

As CMOS scaling continues, the traditional DC device-level hot-carrier reliability criteria becomes difficult to meet for newer generations of technology. In order to satisfy hot-carrier reliability requirements by using AC circuit-level criteria, issues of AC device degradation under circuit operation and impact of device degradation on circuit performance need to be examined. In order to sati...

Comprehensive Physical Modeling of Nmosfet Hot-carrier-induced Degradation

The role of hot-carrier-induced interface states in NMOSFETs is discussed. A new model is proposed based on measurements in several 0.7/~m CMOS technologies of different suppliers. Our model for the first time enables accurate interface state prediction over many orders of magnitude in time for all stress conditions under pinch-off and incorporates saturation. It can easily be implemented in a ...

Hot-carrier reliability of submicron NMOSFETs and integrated NMOS low noise amplifiers

The effects of hot-carrier stress (HCS) on the performance of NMOSFETs and a fully integrated low noise amplifier (LNA) made of NMOSFETs in a 0.18 lm CMOS technology are studied. The main effects of HCS on single NMOSFETs are an increase in threshold voltage and a decrease in channel carrier mobility, which lead to a drop in the biasing current of the transistors. In the small-signal model of t...
