Title
(EN) ION IMPLANTATION PROCESS
(FR) PROCEDE D'IMPLANTATION IONIQUE
Abstract
(EN) An ion implantation process comprises performing mass separation of ions from an ionised source of phosphorous so as to select the P2 ions and reject phosphorous hydride ion species. The P2 ions are injected into a semiconductor substrate. The rejection of phosphorus hydride ions species is facilitated because there are no such species adjacent (in terms of effective mass) the P2 ion species. The use of the P2 ion species also improves the implantation process for shallow implantation depths.
(FR) Un procédé d'implantation ionique consiste à effectuer la séparation des masses à partir d'une source ionisée de phosphore de manière à sélectionner les ions P2 et à rejeter les espèces d'ions hybrides du phosphore. Les ions P2 sont injectés dans un substrat semi-conducteur. Le rejet des espèces d'ions hybrides du phosphore est facilité du fait qu'il n'y a pas de telles espèces proches (en termes de masse effective) de l'espèce d'ions P2. L'utilisation de l'espèce d'ions P2 permet également d'améliorer le procédé d'implantation à de faibles profondeurs d'implantation.
