A New Method for Measuring Ion Implantation Amorphous Dose In Situ

Abstract

ABSTRACTAn in situ method for determining the ion implantation dose necessary to make Si amorphous is developed and utilized. This method is based on measuring ion-implantation-induced in-plane stress. Measurements are carried out for various low energy ions implanted into thin p-type (100) Si. The doses necessary to make Si amorphous obtained by this method are in good agreement with previous data. This technique is sensitive, informative, quick, visual and nondestructive.
