The present invention is directed to a body having a first area and a second area separated by a recess. The recess is dimensioned to reduce, if not prevent a liquid moving along a surface of the body from traveling between the first and second areas. One or more alignment marks may be positioned within one of the first and second areas. In this manner, the recess functions as a moat by reducing, if not preventing, a quantity of the liquid from being in superimposition with the alignment marks. |
