SIJTechnology, Inc. is engaged in the research and development of super-fine inkjet technology based on the research results developed by the National Institute of Advanced Industrial Science and Technology (AIST).
Features of super-fine inkjet technology
The super-fine inkjet technology developed by the Nanotechnology Research Institute of AIST allows the ejection of super-fine droplets much smaller than the conventional droplets ejected by a conventional inkjet printer-less than 1/10 the size and less than 1/1000 the volume of conventional droplets.

Precision placement of nano-materials
Critical to the implementation of nanotechnology is a deposition methodology that allows novel materials to be precisely added to conventional CMOS components in a scalable manner. Out super-fine inkjet technology enables the precise arrangement of various nanomaterials on a any type substrate.

Maskless precision patterning
With traditional patterning method satisfactory liquid placements is a challenge as bulges may develop due to the surface tension of the liquid. The effect is exacerbated as feature sizes approach 10 microns and lower. Our super-fine inkjet technology effectively avoids this problem by accelerating the drying of a line, thus minimizing the disruption in a pattern formed in a liquid state.
Using nanopaste to draw a super-fine wiring pattern
An interesting aspect to metals is that for particles smaller than 20 nm in diameter, the effective melting point decreases dramatically. For example, the melting point of a super-fine silver particle may be as low as room temperature, whereas a micron sized particle of silver melts at 961ºC! Using a solution with these nano-size particles as ink, with out novel printer, enables maskless patterning with a line width of several microns, which is comparable to the photolithographic methods, but at room temperature and normal atmospheric pressure!
Forming a three-dimensional structure
Because super-fine liquid droplets dry very quickly, the droplets can be accumulated to form a three-dimensional structure by shooting them at a fixed target.
