High temperature gate bias
WebWe observe that non-zero gate bias applied during a high temperature anneal following hot-carrier degradation (HCD) impacts degradation recovery in nFETs. The devices are arranged into custom-built arrays and fabricated in a commercial 40 nm bulk CMOS ... 0 Metrics Total Citations 0 research-article WebIn addition, high temperature gate stress tests (HTGS) were performed. Both positive bias temperature stress (PBTI) as well as negative bias stress (NBTI) show well predictable power-law like threshold voltage shifts of the form V GSth ~ (time)n which is similar to Silicon MOSFETs. Within 1000 h stress time at 150°C, the total
