Sub-20nm GaAs-based Cylindrical Gate-All-Around FETs for Improved Performance

2021 2nd International Conference on Robotics, Electrical and Signal Processing Techniques (ICREST), 2021
In this work, a cylindrical gate-all-around field-effect transistor (CGAA FET) has been implemented using gallium arsenide (GaAs) as the channel material instead of the conventional silicon material. The investigations based on the simulations using the Atlas tool of the Silvaco TCAD software prompts out that the GaAs-based CGAA FET is capable of ...

Precise analytical model for short channel Cylindrical Gate (CylG) Gate-All-Around (GAA) MOSFET

Solid-State Electronics, 2013
Abstract A compact analytical model is presented for device electrostatics of nanoscale Cylindrical Gate (CylG) Gate-All-Around (GAA) MOSFET, using isomorphic polynomial function for potential distribution. The model is based on solutions of 3D Laplace and Poisson’s equations for subthreshold and strong inversion region respectively.

A dopingless gate-all-around (GAA) gate-stacked nanowire FET with reduced parametric fluctuation effects

Journal of Computational Electronics, 2018
This paper proposes a gate-all-around silicon nanowire dopingless field-effect transistor (FET), utilizing a gate-stacked technique. The source and drain regions are formed by employing a charge plasma concept, with the application of appropriate work functions for metal contacts.

(Invited) Selective Etches for Gate-All-Around (GAA) Device Integration: Opportunities and Challenges

ECS Meeting Abstracts, 2019
This paper addresses the opportunities and challenges of wet and dry etches in the integration of gate-all-around (GAA) device, which is emerging as a promising solution to replace FinFET [1-3]. For the GAA device fabrication, a quintessential challenge is an isotropic etching of dielectrics, semiconductors, and metals with high selectivity to the ...

Influence of Orientation, Geometry, and Strain on Electron Distribution in Silicon Gate-All-Around (GAA) MOSFETs

IEEE Transactions on Electron Devices, 2011
In this paper, the effects of device orientation, geometry, and strain (uniaxial and biaxial) on the electrostatic properties of different silicon gate-all-around metal-oxide-semiconductor field-effect transistors are thoroughly investigated. We show how the electron density changes with the device orientation and how it depends on the geometry, size ...

Compact modeling for gate-all-around nanowire tunneling FETs (GAA NW-tFETs)

2012 IEEE 11th International Conference on Solid-State and Integrated Circuit Technology, 2012
A compact model for gate-all-around (GAA) nanowire tunneling FETs (NW-tFETs) is developed based on ballistic transport and charge balancing approaches. To account for the carrier injection to the channel from source/drain (S/D) regions for NW FETs, the density-of-states (DOS) charge, which results in the so-called quantum capacitance, is introduced and

SiGe cantilever channel gate-all-around (GAA) fully depleted (FD) PMOSFET with high-¿ and metal gate

2007 65th Annual Device Research Conference, 2007
Scaling the conventional CMOS transistor beyond the 45 nm generation ushers in several fundamental limitations. Control of leakage currents and sustaining electrostatic integrity while maintaining historic enhancements in performance requires such ultra-thin gate-dielectrics and heavily doped bodies that a process window sufficiently large for ...
