A probe mark reading device for reading probe marks stormed on electrode pads
of
semiconductor chips contained in a semiconductor wafer (90), comprising
a CCD camera (20) for taking an image of the semiconductor wafer (90)
and outputting the image as an image signal Si, an optical unit (21) for
optically enlarging a location to be photographed by the CCD camera (20),
a light source (30) for illuminating the location to be photographed by
the CCD camera (20) with a flash of light generated for a short period of
time from when a flash signal Sf is provided, an X-Y stage (40) capable
of changing a position to be photographed by the CCD camera (20) based on
a motor control signal Sm by moving a mounted semiconductor wafer (90) in
an X-direction and a Y-direction, and a computer (10) for providing control
and saving the images after receiving and trimming the image signal Si. With the
above configuration, it is possible to read probe marks in a short time without
a user having to expend much time or effort.
