In the process a very hard stamp is fabricated by first depositing alternating layers of two materials, one of which has very high hardness, on some sacrificial substrate via PVD, CVD or any other deposition procedure that produces alternating layers of selected thickness, from sub 1 nm to above 100 nm.
