The technique may be realized as an ion beam current measurement apparatus having at least a planar Faraday cup and a voltage assembly. The planar Faraday cup is located close to an inner surface of a chamber wall, and intersects an ion beam path. The voltage assembly is located outside a chamber having the chamber wall.

Therefore, the whole ion beam may be received and measured well by the larger cross-section area of the planar Faraday cup on the ion beam path.
