(a) Programmed pattern of a helical structure with a radius of 2.5 μm and an elevation angle of 13°. (b) Cross section of the programmed pattern shown in (a). (c) SEM image of fabricated helical structures using the programmed pattern in (a) before electroless silver plating. (d) SEM image of the fabricated helical structures after electroless silver plating. (e) EDX spectrum of the fabricated structure with silver plating. (f) EDX image of Ag in the fabricated helical structure with silver plating.
