Full textThe goal of this PhD work has been to implement a non linear network analyzer (LSNA), to validate measurements, to develop measurements and analysis tools in time domain in order to understand limiting effects on field effect transistors at microwave frequencies. First, we show the importance of the non linear characterization for the design of active circuits. Second, we de scribe the Large Signal Network Analyzer setup and its implementation. After that, in order to evaluate the performance of this equipment, we have compared measurements provided by equipment and by those coming from other laboratories on the same reference device. ln the next part, we describe the setup of an active load pull large signal network analyzer developed in our laboratory. Then, in order to validate our setup, we compare non linear measurements obtained under in load pull conditions with data coming from simulation performed on a reference device. The following of this work is devoted to an experimental study in time domain, using LSNA, on the lirniting effects of impact ionization inside GaAs HEMT devices. We present sorne experimental results and mainly measurements under large signal conditions in time domain. A non linear electrical model allows us to account for the impact ionization effects on the time domain waveforms. The next part is devoted to a specific study of passivation and surface pretreatrnent carried out on A 10. 81InO.19N/GaN HEMT device. We show the advantages to use the active load pull large signal network analyzer for studying the influence of passivation and surface pretreatrnent on the power performance. To fmish, we discuss on the traps localization and dynamic

Full textThis PhD dissertation presents and analyses various room-temperature circuits for Terahertz detection and generation implemented in CMOS 65nm bulk and 28nm FDSOI throughout the course of the thesis. The work discusses the methodology of design and feasibility of fully-integrated focal-plane arrays of detectors in CMOS technologies as potential commercial solutions for various THz applications. The interesting characteristics of the Terahertz portion (300GHz-3THz) of the Electromagnetic spectrum incite plenty of applications ranging from safe and non-invasive medical imaging (cancer detection, dental imaging, pharmaceutical and other), security screening and chemical detection, safety inspection and quality control, astronomy, ultra-high data-rate communications and many others. However, this region of the Electromagnetic spectrum has been dubbed the THz-Gap due to the lack of commercial sources and detectors. Classical THz-systems, therefore, have been explicitly dominated by expensive technologies that suffer from low-integration levels and high operational costs. Consequently, current THz-products have been limited to single or few pixels only with raster-scanning techniques to produce single THz image-frames. Therefore, and contrary to the current state-of-the-art, developing such applications with commercial viability will require portability and high integration-levels, video-rate speeds, low power-consumptions as well as room-temperature operation. Reasonably, Silicon-based technologies that are the core of the vast majority of commercial and high-end electronic products seem to be a tempting solution to bring this THz-Gap. The investigations of this PhD thesis evolve from the theoretical analysis to the optimisation of naked detectors implemented in various technology nodes and illumination topologies, up to the implementation of a 1 k-pixel video imager that includes on-chip signal multiplexing, amplification and processing. Terahertz source design based on 5-push harmonic oscillators is discussed and aimed at attaining the highest frequencies possible in CMOS. Terahertz imaging systems are also discussed in the context of their corresponding applications, link budgets and feasibility

Full textNowadays, the design of high-frequency broadband power integrated circuits is an important research axis in modern defense systems. This manuscript proposes a study about GaN HEMT in order to highlight its interest for these applications. The first part consists in design and measurement data of a broadband 6-18 GHz power amplifier. The obtained results demonstrate the performance of UMS GH25 technology based on SiC substrate. Unfortunately, for high frequency applications, AlGaN/GaN HEMT is limited by two phenomena that are thermal and trapping effects. Thus, a non-linear electrothermal model including these effects for a HEMT 8x75 μm is proposed. Some specific characterizations have shown limitations of current techniques for trap modeling and their analyses should open new perspectives in this field

Full textL'avènement de substrats de haute pureté nous a permis de réaliser les premiers composant performants et stables, sans dérive observable, au moins sur plusieurs dizaines d'heures d'amplification en régime nominal à pleine excitation. En particulier, une puissance de 50W a été obtenue à 500MHz sur un développement de 19,2mm (2. 6 W/mm), avec une tension de polarisation de 70 V. La disparition des instabilités liés aux substrats nous a permis d'aborder la problématique de la passivation de ces composants, et de percevoir de manière anticipée l'acuité de ce problème fondamental pour la mise au point de transistors latéraux stables fonctionnant à haute tension. Les phénomènes de charge de l'isolant de passivation représentent actuellement l'une des limitations fondamentales de la fiabilité de ce type de composant. L'élimination de ces effets constitue une des clefs principales du développement et de l'industrialisation de la prochaine génération de transistors hyperfréquence de puissance

Full textThis work presents an evaluation of the performances of graphene-based Field-Effect Transistors (GFETs) through electrical compact model simulation for high-frequency applications. Graphene-based transistors are one of the novel technologies and promising candidates for future high performance applications in the beyond CMOS roadmap. In that context, this thesis presents a comprehensive evaluation of graphene FETs at both device and circuit level through development of accurate compact models for GFETs, reliability analysis by studying critical degradation mechanisms of GFETs and design of GFET-based circuit architectures.In this thesis, an accurate physics-based large-signal compact model for dual-gate monolayer graphene FET is presented. This work also extends the model capabilities to RF simulation by including an accurate description of the gate capacitances and the electro-magnetic environment. The accuracy of the developed compact model is assessed by comparison with a numerical model and with measurements from different GFET technologies.In continuation, an accurate large-signal model for dual-gate bilayer GFETs is presented. As a key modeling feature, the opening and modulation of an energy bandgap through gate biasing is included to the model. The versatility and applicability of the monolayer and bilayer GFET compact models are assessed by studying GFETs with structural alterations.The compact model capabilities are further extended by including aging laws describing the charge trapping and the interface state generation responsible for bias-stress induced degradation.Lastly, the developed large-signal compact model has been used along with EM simulations at circuit level for further assessment of its capabilities in the prediction of the performances of three circuit architectures: a triple-mode amplifier, an amplifier circuit and a balun circuit architecture

Full textLa technologie de grille nitrure a été développée pour la filière GaN. Cette technologie a permis de fabriquer des grilles de faibles longueurs avec des topologies variables telles que la grille r, le tout avec un bon rendement de fabrication et une autopassivation. Elle a permis également de réaliser un fossé de grille en utilisant le « digital etching ». Cette technologie a donné la possibilité de fabriquer des composants ayant une longueur de grille de 70 nm tout en conservant un rapport d'aspect favorable. Le troisième et dernier chapitre traite de la caractérisation des transistors HEMTS en régime statique ou d'impulsions, en hyperfréquence et en puissance. Les résultats convaincants montrent tout l'intérêt de la technologie de grille nitrure associé au recess de grille. Ainsi, des composants utilisant ce procédé, ont permis d'obtenir l'état de l'art sur substrat Si(100) avec une puissance maximum, de sortie de 1 W/mm à 2,15 GHz, un gain en puissance de 24 dB et un rendement de 17%

Full textIn the context of high frequency devices fabrication, normally-off transistors offer two benefits: they eliminate the need of a negative voltage supply in the case of Monolithic Microwave Integrated Circuit (MMIC) and would allow the fabrication of logic circuits if integrated with normally-on HEMT.This manuscript exposes the work performed to develop a normally-off HEMT fabrication process compatible with the fabrication of normally-on transistors. To achieve this, we studied two technologies: one based on the combination of a gate recess, fluorine implantation under the gate and gate-oxide deposition while the other is based on the nanostructuration of the source-drain region in order to make GaN FinFET. The first process gave us normally-off transistors with threshold voltage of 1,4 V associated with current density of about 1 A/mm. However, these devices suffer from significant trap effects that are probably due to the gate oxide. The FinFET technology we have developed, as a first trial, still needs a lot of optimization but showed promising results. While a topology lead to an increase of the threshold voltage of about + 3 V compared to the reference, an other one lead to a doubling of the current density

Full textThis thesis presents a study of FDSOI Tunnel FETs (TFETs) from planar to trigate/nanowire structures. For the first time we report functional “Low-Temperature” (LT) TFETs fabricated with low-thermal budget (630°C) process flow, specifically designed for top tier devices in 3D sequential integration. “Dual IDVDS” method confirms that these devices are real TFETs and not Schottky FETs. Electrical characterization shows that LT TFETs performance is comparable with “High-Temperature” (HT) TFETs (1050°C). However, LT TFETs exhibit ON-current enhancement, OFF-current degradation and VTH shift with respect to HT TFETs that cannot be explained via BTBT mechanism. Charge pumping measurements reveal a higher defect density at the top silicon/oxide interface for geometries with narrow widths in LT than HT TFETs. In addition, low-frequency noise analyses shed some light on the nature of these defects. In LT TFETs, we determined a non-uniform distribution of defects at the top surface and also at the tunneling junction that causes trap-assisted tunneling (TAT). TAT is responsible of the current generation that degrades the subthreshold swing. This indicates the tight requirements for quality epitaxy growth and junction optimization in TFETs. Finally, we proposed novel TFET architectures. TCAD study shows that the extension of the source into the body region provides vertical BTBT and a larger tunneling surface. Ultra-thin heavily doped boron layers could allow the possibility to obtain simultaneously a good ON-current and sub-thermal subthreshold slope in TFETs

Full textThis work aims to develop a new high speed transistor in a vertical transport configuration that exploits the favourable transport properties of III-V semiconductor heterostructures based on InAs. This transistor is similar to a heterojunction bipolar transistor (HBT), but has theoretical assets to overcome the fundamental high speed limits of electron transport in HBT. Our approach uses the concept of hot electron transistor in an original InAs/AlSb quantum heterostructure, that we called a quantum hot electron transistor (QHET) or quantum cascade transistor (QCT). This research was almost done in Southern Electronics Institute (IES) under supervision of Dr. Roland Teissier and other work was realized in Micro-Nanotechnology Electronics Institute (IEMN) under supervision of Dr. Mohamed Zaknoune. The QHET is a unipolar vertical transport device made of a InAs/AlSb quantum heterostructure. Its first advantage over npn HBTs is the low base sheet resistance of 250 Ω/□ , accessible with moderate n-type doping levels (typically 1018 cm-3), which is a key parameter for high speed operation. Secondly, electron transport in the short (typically 100nm) bulk InAs collector is mostly ballistic with calculated transit times much shorter than in InP-based devices. We already developed the design and technology of QHET and demonstrated its resonant transports at cryogenic temperature and its improved static operation in smaller device. From these results, we come to develop our QHET structures to achieve high current gain. Using quantum design of thin base, the current gain is about 15. We fabricated QHET with emitter width scaled down to 0.3µm, using a state of the art electron beam lithography process. The junctions are defined using selective chemical etching. The base contact is self-aligned on the emitter contact. We achieved base resistance lower than 50Ω, comparable to state of the art HBTs. The small dimension allowed reaching the high current density regime of up to 1 MA/cm² required for high frequency operation. The static current gain is about 10, but could be increased up to 14 using a new quantum design. The collector breakdown voltage is greater than 1.2 V.Towards high frequency measurement, the substrate must be non-conducting material but InAs substrate is not available. Two technologies were proposed: transferred substrate and metamorphic substrate. For transferred substrate technology, we obtained a response of cutoff frequency of 77 GHz for FT and 88 for FMAX. For metamorphic substrate technology, we performed the growth of the transistor structures on a semi-insulating GaAs substrate. We used a thin GaSb buffer layer for metamorphic growth of the active part of the transistor, with an adequate growth procedure that allows forming mainly 90° misfit dislocations at the interface between the GaAs and GaSb. This technique permits more convenient and reliable processing of the devices, as compared to use of the more standard AlSb thick buffer layer. The frequency response was determined from S-parameters measured with a network analyser up to a frequency of 70 GHz. The measured gains, after de-embedding of the connection parasitic for a device with 0.5x4µm² emitter for JC=350kA/cm² (Ic= 6.0mA, Ib= 0.7mA, Vce=1.3V). The frequency dependence is not conventional on this device, with a resonance in the current gain close to 10 GHz and a slope different from -20 dB/decade for Mason's unilateral gains. Nevertheless, we could extract the cut-off frequencies FT=172 GHz from H21 and FMAX =230 GHz using -20dB/decade extrapolation of maximum stable gain (MSG). The present results confirmed the validity of this novel device concept. In addition, this is the first demonstration of the ability of a hot electron transistor to operate at high frequency at room temperature

Full textThe aim ofthis the sis is to develop a compact model for the cylindrical GAA MOSFET transistor. The objective is to reproduce the electrical behavior of the transistor through a predictive model which could be used for circuit simulations. The transistor is considered first as an ideal device that is to say without any parasitic effects in order to form the model core. Subsequently, the study focuses on the modeling of quantum-mechanical effects. A quantum correction, which takes into account both structural and electrical confinement of carriers in silicon, is then proposed and implemented into the model core. Afterwards, the study concerns the modeling of short channel effects, which are associated to the reduction of the transistor gate length. Moreover, several parasitic effects such as gate leakage currents, GIDL, series resistance and mobility degradation are modeled separately and implemented into the model core. Finally, experimental data measurements lead to the validation of the whole compact model

Full textOrganic field effect transistors (OFETs) have huge potential in the applications of future electronics, such as flexible circuits and displays or medical application. However, stability and performances of OFETs need to be improved, so as to reach the real market applications.First objective of this work is to realize air stable OFETs with state of the art performance. To that end, several approaches have been applied with special focus on process simplification. Small molecule, dinaphtho[2,3-b:2',3‘-f]thieno[3,2-b]thiophene (DNTT) has been chosen as the active layer for all devices studies. Metal electrodes in combination with oxide interfacial layers were investigated to decrease the contact resistance, which not only affects eventual mobility that can be achieved but also complicates circuit design. A systematic study was carried out to fabricate high capacitance dielectric layer and passivating the surface with proper interfacial layers. These approaches allowed to obtain high performance OFET on plastic substrate with high mobility (2.4cm2.V-1.s-1), high current on/off ratio (> 106), low threshold voltage and no hysteresis As the second objective, OFET devices were simulated using GoldenGate (with Cadence Virtuoso® environment) to derive relevant parameters, which helped to design amplifier circuit. Finally, passive component (resistance) has been developed and final circuit was realized and characterized

Co-integrating the magnetic transducer (the sensitive element transforming the magnetic field into an electrical quantity) together with its conditioning electronics onto a same chip allows to implement specific features, which dramatically improve the sensor performances. This work particularly focuses on two types of transducer: the vertical Hall device and a specific magneto-transistor called “CHOPFET”. We developed numerical simulation models in order to predict and optimize the behavior of these transducers. Based on the results, we adapted dedicated signal processing techniques and proposed several innovative magnetic signal conditioning architectures. This led to significant improvement in terms of resolution, offset and power consumption
