Comparative analysis of the intrinsic voltage gain and unit gain frequency between SOI and bulk FinFETs up to high temperatures
This paper presents an experimental analysis of the analog application figures of merit: the intrinsic voltage gain (A(V)) and unit gain frequency, focusing on the performance comparison between silicon triple gate pFinFET devices, which were processed on both Si and Silicon-On-Insulator (SOI) substrates. The high temperature (from 25 degrees C to 150 degrees C) influence and different channel lengths and fin widths were also taken into account. While the temperature impact on the intrinsic voltage gain (A(V)) is limited, the unit gain frequency was strongly affected due to the carrier mobility degradation at higher temperatures, for both p- and n-type FinFET structures. In addition, the pFinFETs showed slightly larger A(V) values compared to the n-type counterparts, whereby the bulk FinFETs presented a higher dispersion than the SOI FinFETs. (C) 2016 Elsevier Ltd.
