New Research Results

Drastically Improving the Sensitivity and Inspection Area of a Thin Film Transistor (TFT) Array Inspection Technology

AIST has greatly improved the sensitivity and inspection area of a thin film transistor (TFT) array inspection technology (a gate modulation imaging technology) by combining an image processing unit that can run at a speed of about 1 gigabyte per second, a CMOS camera with about 4.15 megapixels, high-brightness LED lights, and wide view-field optics. This shortened inspection time to within 3 minutes and expanded the area to 3 cm square. AIST also made it possible to inspect storage capacitors.

Development of a Novel Material for Highly Efficient Spin Control by Voltage

AIST has developed a novel iron-iridium (FeIr) magnetic material for voltage-controlled magnetic memory that achieves highly efficient spin control by voltage. It was discovered that the efficiency of spin control by voltage can be increased about three-fold by using an Ir-doped ultra-thin Fe film. In addition to the efficiency of voltage control, perpendicular magnetic anisotropy, which is important to show the scalability of voltage-torque MRAM, is also improved. The target performance for practical voltage-torque MRAM has been achieved for the first time.

Spintronics Research Center

Creating innovative green IT based on spintronics

The rapid development of IT society is accompanied with a large increase in the power consumption of electronic devices. To reduce the total power consumption of IT appliances, power consumed during input "standby time" as well as active power have to be significantly reduced. To achieve this, it is essential to develop nonvolatile memory, which retains data even after the power is turned off. We are developing low-power-consuming, high-speed, and highly-reliable nonvolatile memory and spin logic device based on spintronics technology. Moreover, we are also developing novel spintronic devices such as nano-sized microwave oscillator called Spin-Torque Oscillator (STO), high-speed physical number generator named Spin Dice, and spin optical devices.

Sensing System Research Center

Hub Center for High-Performance Sensing Toward Safe and Secure Life

In upcoming society (“Society 5.0” in a definition of the government of Japan), where everyone and everything are connected via IoT (Internet of Things), major requirements are sensing and computerizing of various events that happen in “physical space”, and its connection to “cyber space”. Targets of sensing are machine systems such as vehicles and factories, infrastructures such as roads and bridges, work and life environment, and many others. Particularly challenging are invisible objects, including threats of virus or pathogen, and comfort or pain felt with human’s body and mind. Our goal is to visualize the information both inside and outside human being, and to develop high-performance sensing technology that contributes to daily life with safety, security, and both mental and physical richness.
