Here is a quick example script that will create the geometry shown here:

units        metal
atom_style   atomic
lattice      diamond 3.52 origin 0.1 0.1 0.1

region box   block -20.0 20.0 -20.0 20.0 -20.0 20.0
create_box   1 box

region top     plane     0.0  0.0 20.0     0.0  0.0 -1.0
region side1   plane     0.0  0.0  0.0     1.5  0.0  1.0
region side2   plane     0.0  0.0  0.0    -1.5  0.0  1.0
region side3   plane     0.0  0.0  0.0     0.0  1.5  1.0
region side4   plane     0.0  0.0  0.0     0.0 -1.5  1.0
