The present invention defines a system (100) for detecting copper
contamination within a semiconductor manufacturing process. According to
the present invention, a semiconductor wafer (102) is transferred (108)
from a semiconductor manufacturing component (104), which may have
exposed the wafer to copper contamination, to a measurement system (106).
The measurement system measures an electrical value at a plurality of
locations along a surface of the wafer, prior to and after exposure of
the surface to an activation system (112). The activation system is
provided to cause any copper contamination along the surface to form a
precipitate thereon. An analysis component (110) is provided to receive
electrical value and location information from the measurement system and
to identify, from the measurements, the presence and location of copper
contamination along the semiconductor wafer surface.
