Analytical model of quantum threshold voltage in short-channel nanowire MOSFET including band structure effects

Dura J., Martinie S., Munteanu D., Jaud M-A, Barraud S., Autran J-L, CEA/LETI/MINATEC, FR

The particular shape of Gate-All-Around (GAA) nanowires allows a much higher electrostatic control of the active region than conventional devices, as required for the integration at the end-of-roadmap. This architecture is suitable for ultra-scaled devices [...]

Analytical Modelling of Ballistic and Quasi-Ballistic Nanowires:Validation and Application to CMOS Architecture

Martinie S., Munteanu D., Le Carval G., Jaud M-A, Autran J-L, CEA/LETI/MINATEC, FR

We present here an unified analytic model for ballistic and quasi-ballistic Silicon Nanowire (SNW represented in figure 1). Starting from the classical flux method and using the Lundstrom/Natori approaches [1-2], we enhanced them by taking [...]

Performance study of Ballistic and Quasi-Ballistic on Double-Gate MOSFETs 6T SRAM cell

Martinie S., Jaud M-A, Munteanu D., Thomas O., Le Carval G., Autran J-L, CEA/LETI/MINATEC, FR

The impact of ballistic/quasi-ballistic carrier transport on the switch of a CMOS inverter and on the noise margin of a 6T SRAM cell, both based on Double-Gate MOSFETs (DGMOS), is analysed using mixed-mode simulation. To [...]

Compact Model of the Ballistic Subthreshold Current in Independent Double-Gate MOSFETs

Munteanu D., Moreau M., Autran J-L, L2MP-CNRS, FR

Double-Gate structures with independent gates have been recently proposed, allowing a four terminal operation. Independent Double-Gate (IDG) MOSFETs offer additional potentialities, such as a dynamic threshold voltage control by one of the two gates, transconductance [...]

Compact modeling of drain current in Independently Driven Double-Gate MOSFETs

Munteanu D., Autran J-L, Loussier X., Tintori O., L2MP-CNRS, FR

As CMOS scaling is approaching its limits, Double-Gate (DG) MOSFET is envisaged as a possible alternative to the conventional bulk MOSFET. In spite of excellent electrical performances due to its multiple conduction surfaces, conventional DG [...]

Compact modeling and performance analysis of Double-Gate MOSFET-based circuits

Tintori O., Munteanu D., Loussier X., Autran J-L, Regnier A., Bouchakour R., L2MP, FR

Double-Gate (DG) MOS transistors and related multiple-gate device architectures are nowadays widely identified as one of the most promising solutions for meeting the roadmap requirements for the end-of-the-roadmap integration. One of the identified challenges for [...]

Compact Model of drain-current in Double-Gate MOSFETs including carrier quantization and short-channel effects

Loussier X., Munteanu D., Autran J-L, Harrison S., Cerutti R., L2MP, FR

Double-Gate (DG) structure has been in the last years the object of intensive research because its enormous potentiality to push back the integration limits to which conventional devices are subjected. Although the operation of DG [...]

Compact Modeling of Threshold Voltage in Double-Gate MOSFET including Quantum Mechanical and Short Channel Effects

Nehari K., Munteanu D., Autran J-L, Harrison S., Tintori O., Skotnicki T., L2MP-CNRS, FR

Compact modeling of Double-Gate MOSFET incites very much interest presently, since DG is considered to be the best candidate for the integration at the end-of-roadmap. The aim of this work is to develop a short-channel [...]

A Compact Model for the Threshold Voltage of Silicon Nanowire MOS Transistors including 2D-Quantum Confinement Effects

Nehari K., Autran J-L, Munteanu D., Bescond M., L2MP-CNRS, FR

A quantum-mechanical compact model of the threshold voltage for quantum-wire (QW) MOSFETs has been developed. This approach is based on analytical 2D solutions for the decoupled Schrödinger and Poisson equations solved in a 2D cross-section [...]

An Analytical Subthreshold Current Model for Ballistic Double-Gate MOSFETs

Autran J-L, Munteanu D., Tintori O., Aubert M., Decarre E., CNRS, FR

An analytical subthreshold model of ultra-thin double-gate MOSFETs working in the ballistic regime is presented. The present approach captures the essential physics of such ultimate DG devices (quantum confinement, thermionic current) and introduces two main [...]
