摘要

研究了硅酸钆(GdSiO)作为亚10nm栅极第一纳米线(NW) nmosfet的高k介电介质。制备了具有传统SiO2/多晶硅栅极堆的NW-和UTB- nmosfet,并与GdSiO/TiN NW nmosfet进行了比较。采用多NWs并联的特定nmosfet,通过分裂cv法提取有效迁移率,并消除串联电阻以校正测量数据。

Mobility extraction in sub 10nm nanowire nMOSFETs with gadolinium-silicate as gate dielectric
Gadolinium-silicate (GdSiO) as high-k dielectric in sub 10nm gate first nanowire (NW) nMOSFETs is investigated. NW- and UTB- nMOSFETs with conventional SiO2/Poly-Si gate stacks have been fabricated and compared with GdSiO/TiN NW nMOSFETs. Specific nMOSFETs with multiple NWs in parallel have been used to extract the effective mobility by split-CV method and to eliminate the series resistance to correct the measured data.
