Yes. When a photon strikes a CCD, it generates (with a certain probability
represented by the detectors quantum efficiency) an electron. Most of these
electrons are captured by potential wells that define a pixel. However,
these wells are not perfect. The edges are rounded and an electron
generated between pixels may end up in either well.
Slight softening of the pixel edges may be a good thing - it will _reduce_
the effects of alaising. But lets not go there again. ;~)
