Abstract Focused-Electron/Ion-Beam-Induced Deposition (FEBID and FIBID respectively) of metallic materials is one major application of “Dual Beam ” systems, which integrate electron and ion columns. FEBID and FIBID allow local deposition in the targeted place with controllable nanometric lateral size and thickness [1]. FEBID and FIBID of materials is a Chemical Vapour Deposition (CVD) induced by focused electron and ion-beam, respectively [2, 3]. Previous studies on FEBID Pt deposits have shown the decrease of the deposition rate as a function of the beam energy [2-4]. However in the case of FIBID Pt deposits, the deposition rate was found to vary little [2-4]. The microstructure of the Pt deposits have been studied by means of transmission electron microscopy (TEM) [4]. These studies showed that the deposits consist of Pt-rich inclusions in a carbonaceous matrix. In this contribution we present a systematic study of the volume per dose and microstructure of FEBID and FIBID Pt nanodeposits as a function of the beam energy and current [5]. Our experiments were performed in a Dual Beam equipment (Nova 200 NanoLab). For Pt deposition, an automatized gas-injection system (GIS) was used with (CH3)3Pt(CpCH3) as the precursor material. The volume per dose was calculated after performing cross-sections of the
