Patent ID: 7791048

Claim:
An ion implanting apparatus comprising: an ion source part generating an ion beam; a substrate holding part holding a substrate, the ion beam irradiated onto the substrate so that ions are implanted into the substrate; a beam current adjusting part disposed between the ion source part and the substrate holding part, to adjust a beam current according to a position of the ion beam; a doping quantity measuring part disposed on substantially the same surface as the substrate, to measure ion doping quantity in real time; and an ion beam control part connected to the doping quantity measuring part, to control the ion source part and the beam current adjusting part according to the ion doping quantity, wherein the doping quantity measuring part comprises: a plurality of first measurement cells disposed along a first side of the substrate substantially parallel with a scanning direction of the ion beam; and a plurality of second measurement cells disposed along a second side of the substrate opposite to the first side of the substrate.
