The potential of femtoliter-level droplet with super inkjet systems

SIJTechnology, Inc. |

Key Features

  • Super fine patterning

Droplet volume:0.1fl(femtoliter)~10pl(picoliter) 

  • Wide range of viscosity

Viscosity range:0.5~10,000 mPa·s (non-heated)

  • Large variety of usable fluids 

Conductive ink, Insulating ink, Resist ink, UV ink, Solvent ink, Protein materials, etc.

Technical summary

Super Inkjet technology allows the ejection of super-fine droplets much smaller than the droplets ejected by a conventional inkjet printer - 1/10 smaller in size and 1/1000 smaller in volume, that enable to print in extremely high definition patterning even in a sub micro meter resolution with many type of functional materials as ink.

Super Inkjet system for R&D is compact enough, so it can be placed on a desktop. The printer allows single micron scale patterns comparable to the photolithographic methods to be drawn directly under normal temperature and normal atmospheric pressure.


Thanks to the wide range of viscosity.

Super Inkjet technology can print a wide variety of inks.

For example:

  • Conductive ink: Silver, Gold, Cupper nano inks.

  • Polymers: Insulating ink, Resist ink, PEDOT/PSS, Adhesive glue.

  • Functional materials: Organic semiconductor, CNT, catalyst, Q-dots

  • Biomaterial: Protein, Cell-containing solution, DNA solution

Example of applications

In Tandem Contact-Transfer Printing for High-Performance Transient Electronics

(Advanced Electronic Materials DOI: 10.1002/aelm.202200170)

Super inkjet is used fabricated flexible Photodetectors on PI substrate and printed contact electrodes over the aligned ZnO Nano Wires were made using the Au ink.

Inkjet-Printed Nanocavities on a Photonic Crystal Template

(Advanced Materials DOI: 10.1002/adma.201704425)

The authors have demonstrated femtoliter inkjet printing on a 2D PhC template, and the creation of reproducible and structurally tunable high-Q-nanophotonic cavities by drawing lines, dots and crossed strips. A particular attractive feature of this bottom-up fabrication approach is the ability to fine-tune to the sub-10 nm level the thickness of the material deposited on the PhC by controlling the number of printer passes. The coupling strength of PhC photonic molecules was also shown to be controlled simply by changing the separation of the printed strip cavities with submicron resolution.

We will be exhibiting at the most important upcoming event for our industry - The Future of

Electronics RESHAPED conference and exhibition on 17-18th OCT 2023.
