It applies to drug substances produced by chemical syntheses and not previously registered in a region or Member State. Witrynaof introducing impurity atoms into a semiconductor wafer by ion implantation. The purpose of semiconductor doping is to define the number and the type of free charges in a crystal region that can be moved by applying an external voltage. The electrical properties of a doped semiconductor can either be
