Fabrication of Magnetic Nanodots Array Using UV Nanoimprint Lithography and Electrodeposition for High Density Patterned Media

A Magnetic nanodots array fabrication method using ultraviolet nanoimprint lithography (UV-NIL) and electrodeposition was developed. Since the photocurable resin patterned by UV-NIL was directly used for electrodeposition mask, simple and high throughput fabrication process was realized. The CoPt nanodots (diameter: 120 nm) array was formed after the electrodeposition. After chemical mechanical polishing (CMP), the arithmetic mean roughness (Ra) of the track area was smaller than 1 nm.
