Book excerpt: The phenomenon known as Negative Bias Temperature Instability (NBTI) impacts the operational characteristics of Complementary Metal Oxide Semiconductor (CMOS) devices, and tends to have a stronger effect on p-channel devices. This instability is observed with an applied "on" biasing during normal operation and can be accelerated with thermal stress. A normal applied electrical bias on CMOS transistors can lead to the generation of interface states at the junction of the gate oxide and the transistor channel. The hydrogen that normally passivates the interface states can diffuse away from the interface. As a result, the threshold voltage and transconductance will change. These interface states can be measured to determine the susceptibility to NBTI of the devices. For this purpose, a charge pumping experiment and other On-the-Fly techniques at certain temperatures can provide the interface state density and other valuable data. NBTI can impact current technological fabrication processes, such as those provided to the government from IBM. This paper explains this testing of current submicron transistor technology that will be used for military applications.

Book excerpt: This book covers advances in Negative Bias Temperature Instability (NBTI) and will prove useful to researchers and professionals in the semiconductor devices areas. NBTI continues to remain as an important reliability issue for CMOS transistors and circuits. Development of NBTI resilient technology relies on utilizing suitable stress conditions, artifact free measurements and accurate physics-based models for the reliable determination of degradation at end-of-life, as well as understanding the process, material and device architectural impacts. This book discusses: Ultra-fast measurements and modelling of parametric drift due to NBTI in different transistor architectures: planar bulk and FDSOI p-MOSFETs, p-FinFETs and GAA-SNS p-FETs, with Silicon and Silicon Germanium channels. BTI Analysis Tool (BAT), a comprehensive physics-based framework, to model the measured time kinetics of parametric drift during and after DC and AC stress, at different stress and recovery biases and temperature, as well as pulse duty cycle and frequency. The Reaction Diffusion (RD) model is used for generated interface traps, Transient Trap Occupancy Model (TTOM) for charge occupancy of the generated interface traps and their contribution, Activated Barrier Double Well Thermionic (ABDWT) model for hole trapping in pre-existing bulk gate insulator traps, and Reaction Diffusion Drift (RDD) model for bulk trap generation in the BAT framework; NBTI parametric drift is due to uncorrelated contributions from the trap generation (interface, bulk) and trapping processes. Analysis and modelling of Nitrogen incorporation into the gate insulator, Germanium incorporation into the channel, and mechanical stress effects due to changes in the transistor layout or device dimensions; similarities and differences of (100) surface dominated planar and GAA MOSFETs and (110) sidewall dominated FinFETs are analysed.

Available in PDF, EPUB and Kindle. Book excerpt: PUBLIC ABSTRACT: Negative Bias Temperature Instability (NBTI) is becoming a major reliability problem in the semiconductor industry. As time passes, NBTI reduces the capacity of performing correct computations in the microprocessor. Hence, after certain time period, the microprocessor may fail to work as we expect, causing failure of the entire system it is part of. In this research, we study the root cause of the failure due to NBTI effect. Based on our findings, we propose multiple methods to reduce the negative impact of NBTI on a microprocessor. We build a comprehensive experimental setup to consider real world effects in a microprocessor. We evaluate our methods against the previous work and find that our methods substantially improve the processor reliability. This research could be useful in the future to extend lifetime of the processor.
