We calculate analytically the conditions that establish the number
of bound states in finite superlattices as a function of the depth, width
and separation of the wells. We consider a lattice of 
-wells and a
set of rectangular wells. For this latter case, we show how for finite
systems the energy levels already group together in bands separated by gaps.
