may be removed more easily than previously anticipated, as exemplified by the electron-induced dissociation of benzene–Cr(CO)3 [17] and by FEBID using the fluorine-free precursor Cu(tbaoac)2 [18]. The most elegant approach to precursor design yet is to use a bimetallic molecular structure to predefine

fluorine free copper precursor, Cu(tbaoac)2 with the chemical sum formula CuC16O6H26 is introduced for focused electron beam induced deposition (FEBID). FEBID with 15 keV and 7 nA results in deposits with an atomic composition of Cu:O:C of approximately 1:1:2. Transmission electron microscopy proved that
measured from deposited pads was used to simulate the optical response of tip arrays fabricated out of the same precursor and showed good agreement with measurements. This paves the way for future plasmonic applications with copper-FEBID.
