The release line includes internal void arrays for release line. A maximum length of the internal void array for product line Lis equal to a maximum length of the internal void array for release line L, and a minimum length of the internal void array for product line Lis greater than a minimum length of the internal void array for release line L; or the length Lis greater than the length L.
