This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scaling the size of CMOS circuits to extremely small dimensions gets the semiconductor industry to a point where its cornerstone, Silicon-based MOSFET starts to suffer a poor power efficiency. In the quest for alternative solutions cannot be omitted a concept of III-V MOSFET. Its outstanding transport properties hold a promise of reduced CMOS supply voltage without compromising the performance. This can path a way not only to the smaller, greener electronics but also to more co-integrated RF and CMOS electronics. In this context, we present fabrication and characterization of Ultra-Thin body InAs MOSFETs and InAs FinFET. Synergy of a deeply scaled gate length, low access resistance and a high mobility of InAs channel enabled to obtain impressively high drain currents (IMAX=2000mA/mm for LG=25nm). Equally, the introduction of Ultra-Thin body and FinFET channel design provides an improved electrostatic control. A specific feature of the process presented in this work is a fabrication of contacts and channel by localized molecular beam epitaxy MBE epitaxy.

Available in PDF, EPUB and Kindle. Book excerpt: Le système autonome nécessite une consommation d'énergie inférieur à 100μW pour qu’ils puissent récupérer l’énergie environnementale. Le transistor MOSFET, étant le composé principal de ce système, peut permettre cela en améliorant ces performances. Le matériaux III-V présente un intérêt à être appliqué au transistor MOSFET en considérant ses propres propriétés tel la haute vitesse thermique d’électron, la haute vitesse de saturation, la faible bande interdite. D'aussi hautes performances de transistor avec de basse consommation d'énergie peut être envisagé grâce au MOSFET III-V. Des technologies de fabrication de MOSFET In0.53Ga0.47As ont été développées avec ces mesures statiques et dynamiques. Un IdMAX=180mA/mm, gmMAX=110mS/mm, fT=150GHz, et fMAX=47GHz ont été obtenus pour un transistor de longueur de grille de 50nm. Différentes voies d’amélioration ont été étudiées y compris le procédé gate-last comparé au gate-first, l’effet PDA, et l’effet PPA. Le procédé gate-last démontre moins de dégradation de l’oxyde avec de meilleures performances que gate-first. PDA n’a pas d'effet important sur les performances du transistor. PPA a démontré un effet de passivation de certains défauts dans l’oxyde et dans l’interface. Des structures alternatives ont été étudiées comme la structure MOSHEMT de maille adapté et pseudomorphique, montrant de meilleures performances avec une IdMAX=300mA/mm, gmMAX=200mS/mm, fT=200GHz et fMAX=50GHz pour un transistor de longueur de grille de 100nm. Ces performances DC sont loin de l’état de l’art, tandis que les performances RF sont parmi les meilleures. La perspective de ce travail est d’améliorer la qualité d’oxyde en baissant le budget thermique et aussi d'utilier de prometteuses strucutres comme MOS-COMB (la structure MOS-Thin body avec couche barrière entre l’oxyde et le semiconducteur). La structure MOSFET InAs de haute performance pourrait aussi être envisagé en réduisant le budget thermique au cours de la fabrication.

This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: La réduction de la puissance consommée des transistors à effet de champ (MOSFETs) est un challenge pour le futur de la nanoélectronique. En 2025, l'Agence Internationale de l'Énergie (AIE) estime qu'il y aura environ 50 milliard d'objets autonomes et nomades nécessitant alors une faible puissance consommée. L'apparition de nouveaux dispositifs tels que les transistors à effet tunnel (TFETs) ou les transistors à ionisation par impact (I MOSFETs) permettra potentiellement de réduire la puissance consommée de ces objets. Dans ce travail de thèse, nous avons étudié pour la première fois le transistor à ionisation par impact à base de matériaux III V des filières arséniée et antimoniée. La structure pin, composant principal du I MOSFET, est tout d'abord étudiée. L'ensemble des briques technologiques des I MOSFET a ensuite été développé, et en particulier l'interface entre l'oxyde et le semiconducteur III-V qui a été optimisée par un traitement innovant par plasma d'oxygène (O2). Ce traitement a montré une amélioration de la qualité de l'interface oxyde/semiconducteur conduisant à une commande des charges beaucoup plus efficace. Pour finir, nous avons montré les études, fabrications et caractérisations d'un transistor à effet tunnel InGaAs et d'un I MOSFET GaSb présentant une architecture verticale où la grille est auto-alignée.

Download or read book Magnetism in Condensed Matter written by Stephen Blundell and published by OUP Oxford. This book was released on 2001-10-05 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: An understanding of the quantum mechanical nature of magnetism has led to the development of new magnetic materials which are used as permanent magnets, sensors, and information storage. Behind these practical applications lie a range of fundamental ideas, including symmetry breaking, order parameters, excitations, frustration, and reduced dimensionality. This superb new textbook presents a logical account of these ideas, staring from basic concepts in electromagnetsim and quantum mechanics. It outlines the origin of magnetic moments in atoms and how these moments can be affected by their local environment inside a crystal. The different types of interactions which can be present between magnetic moments are described. The final chapters of the book are devoted to the magnetic properties of metals, and to the complex behaviour which can occur when competing magnetic interactions are present and/or the system has a reduced dimensionality. Throughout the text, the theorectical principles are applied to real systems. There is substantial discussion of experimental techniques and current reserach topics. The book is copiously illustrated and contains detailed appendices which cover the fundamental principles.
