Research outline

We are creating products based on the metalorganic decomposition (MOD) method. his method is a technique to produce oxides with various electrical properties. Furthermore, we have discovered that oxides and intermediates fabricated by this MOD method have specific characteristics. Our research and development of new sensing devices and patterning methods are based on the combination of these features and semiconductor processes.

Highly sensitive oxide sensing devices

We have been researching and developing oxide thin-film transistor-type nucleic acid sensors that enable rapid and sensitive measurement.

Oxide Mold Formation Technology

We have developed a low-energy, low-cost direct printing method for oxides using nanoimprinting. This technique enables easy fabrication of sub-micron scale patterns.
