Unified Modeling of Multigate MOSFETs Based on Isomorphic Modeling Principles

Fjeldly T.A., Monga U., Norwegian University of Science and Technology, NO

A compact, unified and analytical model is presented for the 3D electrostatics of nanoscale, multigate MOSFETs. The model is based on solutions of the 3D Laplace equation (subthreshold) and Poisson’s equation (above threshold), where suitable [...]

Analytical Solutions to Model the Line Edge Roughness and its Effect on Subthreshold Behavior of DG FinFETs

Monga U., Fjeldly T.A., Norwegian University of Science and Technology, and University Graduate Center (UNIK), NO

Statistical variability such as line edge roughness (LER) and random dopant effects have become major concerns in the nanoscale regime. Due to the intrinsic body, multigate devices such as FinFETs don’t suffer from random dopant [...]

Compact Subthreshold Modeling of Rectangular Gate and Trigate MOSFETs

Fjeldly T.A., Monga U., Norwegian University of Technology, NO

We have previously shown that the subthreshold potential distribution of DG and circular gate MOSFETs can be precisely modeled using conformal mapping techniques. Simpler, unified models suitable for circuit design can also be established for [...]

Subthreshold Quantum Ballistic Current and Quantum Threshold Voltage Modeling for Nanoscale FinFET

Monga U., Fjeldly T.A., UniK/Norwegian University of Science and Technology, NO

A subthreshold quantum ballistic current model and a quantum threshold voltage model is presented for nanoscale FinFET.The eigenvalues are determined by solving Schrödinger equation along the gate-to-gate axis. The current is then modeled using Natori’s [...]

Compact Quantum Modeling Framework for Nanoscale Double-Gate MOSFET

Monga U., Fjeldly T.A., Norwegian University of Science and Technology, NO

A quantum mechanical modeling framework for ultra-thin body double-gate MOSFETs operating in subthreshold and near-threshold regime is presented. For subthreshold conditions, we have assumed that the electrostatics is dominated by capacitive coupling between the body [...]
