Abstract

Highlights • Laser-induced transfer is used for the printing of multilayered microcapacitors • The dielectric film is made of PVP, and the electrodes are made of Ag • Thermal behaviour of the polymer is discussed with respect to the laser processing • The structure and electrical properties of the capacitors are discussed Ag/polyvinylphenol (PVP) multilayered pixels are printed by laser-induced forward transfer (LIFT) technique for thin film microcapacitor applications. The third harmonic (3ω/355 nm, τ = 50 ps) of a solid state neodymium-doped yttrium aluminium garnet (Nd:YAG) laser source is employed throughout our LIFT experiments. By selecting adequate printing parameters (e.g. donor thickness, laser fluence, background pressure), we show how functional microcapacitors are fabricated. At ∼350 μm in lateral size and 300 nm thickness of the dielectric film, the pixels have capacities in the picofarad range. We discuss the laser influence during the pixel transfer process and highlight the polymer's thermal behaviour.
