An 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.
