“…In recent years, printed electronic technologies have attracted increasing attention, such as roll-to-roll printing [1], screen printing [2], gravure printing [3], and inkjet printing [4]. In comparison with the lithography process [5], printed electronic technologies have the advantages of being cheap, flexible, highly efficient, and environmentally friendly. Therefore, many manufacturers have attempted to make use of these technologies to replace the traditional process.…”

Non-contact, direct-write aerosol jet (AJ) printing technology using a variety of functional nanomaterial inks has been regarded as one of the most promising approaches for large-area additive manufacturing. The development and atomization of inks have a considerable effect on the printing quality. Therefore, in this study, the effect of a specific ratio of silver nanoparticle ink and a cosolvent of propylene glycol monomethyl ether (PGME) and ethylene glycol (EG) was investigated. The results indicated that the proportion of the solvent in the silver nanoparticle ink could affect the electrical characteristics of the printed lines. The prepared conductive ink with 95% silver nanoparticle ink and 5% co-solvent at a curing temperature of 180°C demonstrated superior electrical conductivity and adhesion on the substrate.

“…To control and manipulate the wetting behavior of droplets on the substrate, diverse methods for fabricating chemically patterned surfaces have been reported in the last decades. Various techniques including transfer printing, microcontact printing, soft lithography, , and inkjet printing , have been used to fabricate a chemically patterned surface with hydrophobic and hydrophilic wettability contrast. Zheng et al utilized the transfer printing technique and PDMS-based stamps to functionalize the substrates to generate hydrophilic and hydrophobic patterns, which is a contact approach for printing and requires high processing temperatures.…”

“…Lee et al 23 developed a simple and low-cost surface wettability patterning based on soft lithography processes to control the printing variation. Sung et al 24 combined inkjet printing with soft lithography and produced a surface wettability contrast up to 104°. Park et al 26 systematically investigated the influence of ink viscosity, deposition speed, solvent polarity, and boiling point and obtained high resolution and fine pitch printed silver nanoparticulate electrodes.…”

In inkjet printing technology, one important factor influencing the printing quality and reliability of printed films is the interaction of the jetted ink with the substrate surface. This short-range interaction determines the wettability and the adhesion of the ink to the solid surface and is hence responsible for the final shape of the deposited ink. Here, we investigate wetting morphologies of inkjet-printed inks on patterned substrates by carefully designed experimental test structures and simulations. The contact angles, the surface properties, and drop shapes, as well as their influence on the device variability, are experimentally and theoretically analyzed. For the simulations, we employ the phase-field method, which is based on the free energy minimization of the two-phase system with the given wetting boundary conditions. Through a systematic investigation of printed drops on patterned substrates consisting of hydrophilic and hydrophobic areas, we report that the printed morphology is related not only to the designed layout and the drop volume but also to the printing strategy and the wettability. Furthermore, we show how one can modify the intrinsic wettability of the patterned substrates to enhance the printing quality and reliability. Based on the present findings, we cast light on the improvement of the fabrication quality of thin film transistors.

“…Another important issue in nanoimprinting is how the resist material is deployed on top of the substrate surface before imprinting. There are two typical ways: (1) spin-coating to form a resist layer, and (2) droplet injecting to form an array of small resist droplets [10,11,[19][20][21]. Although rarely seen before, it is also possible to have the third choice of deploying a single large droplet of resist material for imprinting.…”

This paper proposes an innovative nanoimprinting method that features imprinting a single droplet of resist and spreading it from center to edge to fully cover a full wafer substrate. Important advantages of this type of nanoimprinting include avoiding air bubble trapping, forming conformal mold/substrate contact, minimizing residual layer thickness, and saving the amount of resist being used. It also makes the demolding process much easier and more successful. To realize this nanoimprinting method, an imprinting tool is designed, constructed, and experimentally tested, and three key components are developed. First of all, a soft mold is integrated into a dovetailed metal ring so that it can be fixed at its edge and deformed by external force. Secondly, two independent loading mechanism are installed so that a soft mold can be initially deformed to form a point contact with a substrate and then followed by imprinting process. Finally, an elastomer cushion pad with a pre-designed convex surface profile is used to convert the loading force into a specific distributed contact pressure which can drive the resist flow. Nanoimprinting experiments have been carried out for pattering micro-scaled and nano-scaled structures on 4″ glass wafers. Excellent imprinting results are observed. The potentials and future perspectives of the proposed nanoimprint system will be addressed.
