Abstract :
The origin of the large Vt shift observed in planar FDSOI is the creation of negative charge states in the BOX by F implant. F implant is a suitable approach for planar FDSOI SoC integration with single WF metal gate, but NOT for MuGFETs. F implant degrades electron mobility and the degradation is a function of F dose. The hole mobility is unaffected by F implant.
