Integration of Single-crystal Tunnel Junction Elements in LSI by 300 mm Wafer Bonding

Researchers in AIST developed fabrication process technology to integrate single-crystal memory elements for non-volatile memory MRAM in silicon LSI. Non-volatile memory MRAM consists of recording bits comprised of magnetic tunnel junctions (MTJs), semiconductor transistors (CMOS) used as bit selector, metal interconnects, etc. This memory is fabricated by directly depositing polycrystalline MTJs with magnesium oxide tunnel barriers onto polycrystalline metal wires. However, MRAM is expected to reach its scaling limit with this conventional technology due to increasing performance variations and insufficient material properties of polycrystalline MTJ elements. Therefore, single-crystal MTJs with new materials and integration technology for the single-crystal MTJs are attracting attention as a solution for extend the scalability.

Optical Switch Technology with the World's Largest Capacity of 125 Million Gigabytes per Second and over 100,000 Ports

Researchers in AIST demonstrated developed that the world's largest total optical switch capacity of 125 million Gbps can be achieved in a 131,072-port optical switch network. This corresponds to the capacity to transmit the data of 600,000 or more Blu-ray discs per second.
This study used the world's largest capacity 32×32 port optical switch developed by AIST to conduct a circular transmission experiment in which a wideband optical signal was transmitted through the same optical switch nine times. Furthermore, the behavior of crosstalk in the optical switch was statistically analyzed, and a general theory for maximizing the number of optical switch ports was established. These results satisfy the requirements of optical switches demanded by next-generation data centers and supercomputers (See figure), and this technology will contribute to high-capacity, low-latency next-generation information infrastructure.

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.
