Out-of-plane bending based on SiN-ion-irradiation and bilayer structures for easy access for micromanipulation
Bending of suspended silicon nitride stripes is introduced here using two methods. Focused ion beam (30kVGa) irradiation of 200nm membrane produces bending up. Deposited 20nm Cr layer shows tensile stress producing bending of structures. Out-of-plane bending renders structures easer accessible for micromanipulation. Schemes for attaching exchangeable tips to AFM are elaborated.
