"Die Ionenimplantation ist ein Verfahren zur Einbringung von Fremdatomen (in Form von Ionen) in ein Grundmaterial, Dotierung genannt. Auf diese Weise lassen sich die Materialeigenschaften (meistens die elektrischen Eigenschaften) des Grundmaterials verändern. Das Verfahren wird unter anderem in der Halbleitertechnik genutzt. Entsprechende Anlagen zur Ionenimplantation werden als Ionenimplanter bezeichnet. " - Lss theory ion implantation
