Abstract

This work analyzes the interface traps density (D_it) at the SiO₂/SiGe interface of a buried SiGe stressor SOI substrate, and demonstrates the impact of those traps on the effective resistivity (ρ_eff) of the substrate. The C-V behavior of MOS capacitors and the RF insertion loss along coplanar waveguide transmission lines on various substrates are measured. TCAD simulations are employed to interpret the traps characteristics and to forecast the RF performance of a buried SiGe stressor SOI wafer having a high resistivity handle Si substrate. The results demonstrate that thanks to the interface traps introduced by the SiGe layer the substrate effective resistivity (ρ_eff) is enhanced.
