Improved Channel Hot-Carrier Reliability in p-FinFETs With Replacement Metal Gate by a Nitrogen Postdeposition Anneal Process

---

Channel hot-carrier (CHC) reliability in p-FinFET devices is studied related to the postdeposition anneal (PDA) process. Clearly reduced CHC degradation is observed with N2-PDA at the VG = VD stress condition. The interface defect density degradation calculated from the subthreshold slope is similar in the reference and PDA devices. However, the pre-existing high-k bulk defect is lower in the PDA-treated device as observed by the low-frequency-noise measurement. This leads to less hot/cold-carrier injection into the bulk defects at the high field under the VG = VD condition, where a higher charge trapping
component is expected than under the classical VG ∼ VD/2 condition. The responsible bulk defect is pre-existing, not generated during the CHC stress as proven by the stress-induced leakage current analysis.
Index Terms—Hot carrier, charge trapping, multi-gate FET, FinFET, logic device.
