Functional multilayered capacitor pixels printed by picosecond laser-induced forward transfer using a smart beam shaping technique

Investigations on laser printing of microcapacitors using poly (methyl methacrylate) dielectric thin films for organic electronics applications

“…Successive printing and overlapping of AgNP lines formed homogeneous pads (Figure 2b). After such pads were fabricated (of different lateral sizes ranging from several hundreds of microns and up to millimetres), they were cured in an oven [16,22,23]. We have already demonstrated the transfer of OTFT pixels, as simple thin films or multilayered structures, and have shown that these polymeric materials are sensitive to laser irradiation (photochemically induced effects) and the transfer/printing procedure (mechanical damage) [33,34].…”

“…The flexible plastic receiver substrate is 125 µm thick, made of polyimide (Kapton HN). Further details of these procedures are presented elsewhere [16,22,23]. The Ag/PMMA donor substrates were also produced on quartz substrates, as follows.…”

“…a dynamic release layer (DRL) [3,8,12,13], or by using a specially designed printing system, i.e. smart beam shaping (SBS) technique [14][15][16], liquid-crystal spatial light modulators (SLM) or digital micromirror devices (DMD) [17][18][19]. Furthermore, by downscaling such laser printing techniques, nanometer-size objects can be printed, e.g.…”

“…by using an array of transparent microspheres (microlenses) [20,21]. We have previously investigated the laser fabrication of various organic electronic devices by using polymers such as polyvinylphenol (PVP) and parylene-C (Py-C) [16,[22][23][24]. In this paper, we present results and discuss on thin films of poly(methyl methacrylate) (PMMA), when used as a dielectric in multilayer microcapacitors.…”

Desarrollo de procesos para formación de contactos con láser para módulos thin film CIGS para aplicaciones fotovoltaicas

“…LIFT has been used to print materials as diverse as DNA for sensors [69], ITO nanoparticles for thin film solar cells [70], organic semiconductors for organic light emitting diodes (OLEDs) [71], bis-pyrene compound for organic think film transistors (OTFT) [72], organic polymer and silver thin films for transducer or sensing device [73], amorphous silicon films for silicon heterojunction solar cell [74], congruent silver nanopaste transfer for double split-ring resonator and interconnection for connecting discrete devices in circuits [75] etc.…”
