Compact modeling for UTBB-FDSOI technologies: Main challenges and possible solutions

Poiroux T., CEA-LETI, FR

Fully-Depleted Silicon-On-Insulator (FDSOI) technologies featuring Ultra-Thin silicon Body and Buried oxide (UTBB) have now entered into industrial production stage. These technologies present several decisive advantages over other options, such as excellent transistor electrostatic control, very [...]

Modeling Independent Multi-Gate MOSFET

Duarte J.P., Khandelwal S., Chang H-L, Chauhan Y.S., Hu C., University of California-Berkeley, US

In this paper a fully-featured turn-key compact model for independent multi-gate MOSFETs is presented. This industry standard compact model is called BSIM-IMG. The two independent (front- and back-gate) control of the channel charge in these [...]

Analytical Surface Potential Calculation in UTBSOI MOSFET with Independent Back-Gate Control

Khandelwal S., Chauhan Y.S., Karim M.A., Venugopalan S., Sachid A., Niknejad A., Hu C., Norwegian University of Science & Technlogy, NO

An analytical method for calculation of front- and back-gate surface-potential in ultra-thin body SOI MOSFETs is presented. The method allows surface-potential calculation with independent back-gate control which is very important in these devices. The calculated [...]

Compact Models for sub-22nm MOSFETs

Chauhan Y.S., Lu D., Venugopalan S., Morshed T., Karim M.A., Niknejad A., Hu C., University of California-Berkeley, US

FinFET and UTBSOI FET (or ETSOI) are the two promising multi-gate FET candidates for sub-22nm CMOS technology. BSIM multi-gate FET models (BSIM-CMG and BSIM-IMG) are the surface potential based physical compact models for FinFET and [...]

RF Modeling for FDSOI MOSFET and Self Heating Effect on RF Parameter Extraction

Wan H., Su P., Fung S.K.H., Dept of EECS, UC Berkeley, US

In this paper, the BSIMSOI RF model for FDSOI MOSFET is introduced and verified. Self-heating effect plays an important role in RF S-parameter fitting and the thermal resistance needs to be correctly extracted. A new [...]
