Developed an Integrated Circuit That Automatically Compensates for the Sensitivity of High-performance Magnetic Sensors

A researcher at AIST, in collaboration with Aichi Steel Corporation, has developed a highly sensitive magnetic sensor that can automatically compensate for fluctuations in detection sensitivity due to manufacturing variations and environmental changes.
Compact, highly sensitive magnetic sensors are needed in a wide variety of applications, including industrial and biological measurement. To apply them to fields such as IoT, their sensitivity must be maintained at a constant level. The cost of manually adjusting sensitivity has hindered the expansion of applications for small, high-sensitivity magnetic sensors.
By combining an application-specific integrated circuit (hereinafter referred to as "ASIC") with an automatic correction function originally designed by AIST and a magnetic impedance element (hereinafter referred to as "MI element") developed by Aichi Steel Corporation, the fluctuation of the magnetic detection sensitivity was reduced to 1/3 of its original level. This automatic calibration technique does not require a special test mode for the process, and can be performed in the background during normal sensing operation. The digital-output architecture achieves both easy handling of output signals and low power consumption. This approach is expected to expand the range of applications for compact, high-sensitivity magnetic sensors.

Elucidating the Switching Characteristics of Transistors Operating at Cryogenic Temperatures

Researchers at AIST have elucidated the low-temperature operation mechanism of transistors, which had been a mystery until now.
The performance of transistors, which are building blocks of integrated circuits, change depending on the temperature. Therefore, understanding the transistor characteristics at their operating temperatures is important for designing integrated circuits. Recently, integrated circuits for qubit control operating at temperature as low as 4 Kelvin (-269.15 °C) have been developed for realizing large-scale integrated quantum computers. However, the switching characteristics of transistors at low-temperature such as 4 Kelvin (-269.15 °C) cannot be explained by the conventional semiconductor physics and have remained a mystery. In this research, by measuring the transistor characteristics at deep cryogenic temperature of 0.015 Kelvin (-273.135 °C), which is two orders of magnitude lower than the operating temperature of 4 Kelvin (-269.15 °C), it was revealed that the electron capture at oxide/semiconductor interface trap determines the switching characteristics of transistors. This is a new finding that unravels a remaining mystery in low-temperature semiconductor physics and will contribute to improving the performance of quantum computers.

Research Laboratory

Open Innovation Laboratory

Since FY 2016, as a part of the “Open Innovation Arena concept” promoted by the Ministry of Economy, Trade and Industry (METI), AIST has created the concept of “open innovation laboratories” (OILs), collaborative research bases located on university campuses, and has been engaged in their provision. We are planning to establish more than ten OILs by FY 2020.

AIST will merge the basic research carried out at universities, etc. with AISTʼs goal-oriented basic research and applied technology development, and will promote bridging research and evelopment and industry by the establishment of OILs.

Cooperative Research Laboratories

In order to conduct research and development more closely related to strategies of companies, we have established collaborative research laboratories, bearing partner company names.

Partner companies provide their researchers and funding, and AIST provides research resources, such as its researchers, research facilities, and intellectual property. The loaned researchers of companies and AIST researchers jointly conduct research and development.

By setting up cooperative research laboratories, we will accelerate the commercialization of our goal-oriented basic research and application research with partner companies.
