Available in PDF, EPUB and Kindle. Book excerpt: CE TRAVAIL EST CONSACRE A L'ETUDE DES DEFAUTS CREES PAR IMPLANTATION LOCALISEE DES PROTONS DANS LES ECHANTILLONS DE SILICIUM. NOUS AVONS REALISE TROIS TYPES D'ETUDES. PAR L'ETUDE DU PROFIL DE RESISTIVITE DES ECHANTILLONS IRRADIES, NOUS AVONS PU DETERMINER QUE L'IMPLANTATION DONNAIT LIEU, APRES RECUIT THERMIQUE A 400C, A DEUX TYPES DE DEFAUTS AYANT DES COMPORTEMENTS ELECTRIQUES DIFFERENTS. LES PREMIERS LOCALISES ENTRE LA SURFACE DE L'ECHANTILLON ET LA PROFONDEUR D'ARRET DES PARTICULES SE TRADUISENT PAR UNE AUGMENTATION DE LA RESISTIVITE. QUANT AUX SECONDS DEFAUTS, ILS SONT ESSENTIELLEMENT LOCALISES A LA PROFONDEUR D'ARRET ET LEUR ACTIVITE ELECTRIQUE SE TRADUIT PAR UNE DIMINUTION LOCALE DE LA RESISTIVITE. CES DERNIERS DEFAUTS POURRAIENT ETRE ATTRIBUES A L'ACTIVITE DE L'HYDROGENE IMPLANTE. LES METHODES CAPACITIVES (C-V ET DLTS) NOUS ONT PERMIS DE DETERMINER LE PROFIL DE CONCENTRATION DES PORTEURS DE CHARGE DANS L'ECHANTILLON APRES IRRADIATION. ELLES NOUS ONT SURTOUT PERMIS DE REPERTORIER (PAR SPECTROSCOPIE DLTS) L'ENSEMBLE DES DEFAUTS CREES PAR IMPLANTATION A DIFFERENTES PROFONDEURS

This book was released on 1996 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'ETUDE DES PHENOMENES MIS EN JEU DANS L'INTERACTION DES PARTICULES CHARGEES OU NON AVEC LA MATIERE OCCUPE UNE PLACE SANS CESSE CROISSANTE SURTOUT DANS LE DOMAINE DE L'ELECTRONIQUE. LES DEFAUTS PRODUITS LORS DE L'IMPLANTATION ONT DES REPERCUSSIONS SUR LES PROPRIETES ELECTRIQUES DES MATERIAUX ET SONT DONC SUSCEPTIBLES DE MODIFIER LES CARACTERISTIQUES DES COMPOSANTS. CE TRAVAIL EST CONSACRE A L'ETUDE DES DEFAUTS CREES PAR L'IMPLANTATION DE PROTONS OU DE PARTICULES ALPHA DANS LE SILICIUM. DANS CE BUT, NOUS AVONS DEVELOPPE UN DISPOSITIF D'IMPLANTATION PERMETTANT D'IRRADIER DES ECHANTILLONS DE DIX CENTIMETRES DE DIAMETRE. POUR IDENTIFIER LES DEFAUTS CREES PAR L'IMPLANTATION D'IONS ET OBSERVER LEURS EFFETS SUR LE SILICIUM, NOUS AVONS UTILISE QUATRE METHODES DE CARACTERISATION. LA MESURE DE LA RESISTANCE DE CONSTRICTION SUR DU SILICIUM IMPLANTE DE TYPE N, MONTRE QUE LA QUANTITE DE DEFAUTS CREEE PAR L'IMPLANTATION DE PARTICULES ALPHAS EST PLUS IMPORTANTE QUE CELLE CREEE PAR DES PROTONS A FLUENCE EGALE. PAR MESURE C-V (CAPACITE-TENSION), NOUS AVONS MONTRE QUE CONTRAIREMENT AUX PARTICULES ALPHAS, L'IMPLANTATION DE PROTONS INDUIT DES NIVEAUX DONNEURS SUPERFICIELS APRES RECUIT. CES NIVEAUX SONT LIES A L'ACTIVITE DE L'HYDROGENE IMPLANTE. LES MESURES D.L.T.S. MONTRENT QUE LA PLUPART DES CENTRES PIEGES A ELECTRONS CREES EN FIN DE PARCOURS DES IONS SONT COMMUNS AUX DEUX PARTICULES. DANS LE CAS D'UNE IMPLANTATION D'ALPHAS, IL APPARAIT UN NIVEAU QUE NOUS ATTRIBUONS A UN AGREGAT DE LACUNES. AFIN DE CARACTERISER LES DEFAUTS CREES PAR DES IMPLANTATIONS A FORTE DOSE, NOUS AVONS UTILISE L'ANALYSE PAR ANNIHILATION DE POSITONS. POUR UNE IMPLANTATION DE PROTONS, UN PROFIL DE BILACUNE A ETE MESURE ET PEUT ETRE CORRELE AVEC LE PROFIL DE RESISTANCE DE CONSTRICTION

This book was released on 2003 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'implantation ionique est couramment utilisée dans l'industrie des semi-conducteurs aussi bien pour le dopage des matériaux que pour en améliorer la pureté. Les défauts créés par implantation/irradiation peuvent améliorer ou détériorer les performances des dispositifs électroniques. Nous avons étudié par spectroscopie capacitive les défauts électriquement actifs créés par irradiation dans le 4H-SiC. Nous avons caractérisé l'un de ces défauts, le centre S, en déterminant sa signature et ses cinétiques d'apparition et de recuit. Par ailleurs nous avons étudié les défauts créés par implantation d'hélium à forte dose dans le Si principalement par Microscopie Electronique à Transmission. Nous avons montré que la nature des défauts (cavités et défauts de type interstitiel) et leur évolution au cours d'un recuit dépendent fortement de la température d'implantation. Les effets d'implantations multi-énergies à haute température sont aussi présentés.

This book was released on 2013-11-27 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silicon on Insulator is more than a technology, more than a job, and more than a venture in microelectronics; it is something different and refreshing in device physics. This book recalls the activity and enthu siasm of our SOl groups. Many contributing students have since then disappeared from the SOl horizon. Some of them believed that SOl was the great love of their scientific lives; others just considered SOl as a fantastic LEGO game for adults. We thank them all for kindly letting us imagine that we were guiding them. This book was very necessary to many people. SOl engineers will certainly be happy: indeed, if the performance of their SOl components is not always outstanding, they can now safely incriminate the relations given in the book rather than their process. Martine, Gunter, and Y. S. Chang can contemplate at last the amount of work they did with the figures. Our SOl accomplices already know how much we borrowed from their expertise and would find it indecent to have their detailed contri butions listed. Jean-Pierre and Dimitris incited the book, while sharing their experience in the reliability of floating bodies. Our families and friends now realize the SOl capability of dielectrically isolating us for about two years in a BOX. Our kids encouraged us to start writing. Our wives definitely gave us the courage to stop writing. They had a hard time fighting the symptoms of a rapidly developing SOl allergy.

This book was released on 2001-05-31 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Device and Circuit Cryogenic Operation for Low Temperature Electronics is a first in reviewing the performance and physical mechanisms of advanced devices and circuits at cryogenic temperatures that can be used for many applications. The first two chapters cover bulk silicon and SOI MOSFETs. The electronic transport in the inversion layer, the influence of impurity freeze-out, the special electrical properties of SOI structures, the device reliability and the interest of a low temperature operation for the ultimate integration of silicon down to nanometer dimensions are described. The next two chapters deal with Silicon-Germanium and III-V Heterojunction Bipolar Transistors, as well as III-V High Electron Mobility Transistors (HEMT). The basic physics of the SiGe HBT and its unique cryogenic capabilities, the optimization of such bipolar devices, and the performance of SiGe HBT BiCMOS technology at liquid nitrogen temperature are examined. The physical effects in III-V semiconductors at low temperature, the HEMT and HBT static, high frequency and noise properties, and the comparison of various cooled III-V devices are also addressed. The next chapter treats quantum effect devices made of silicon materials. The major quantum effects at low temperature, quantum wires, quantum dots as well as single electron devices and applications are investigated. The last chapter overviews the performances of cryogenic circuits and their applications. The low temperature properties and performance of inverters, multipliers, adders, operational amplifiers, memories, microprocessors, imaging devices, circuits and systems, sensors and read-out circuits are analyzed. Device and Circuit Cryogenic Operation for Low Temperature Electronics is useful for researchers, engineers, Ph.D. and M.S. students working in the field of advanced electron devices and circuits, new semiconductor materials, and low temperature electronics and physics.
