Outline

In this research, we aim to achieve breakthrough performance improvement of photo-functional devices such as organic LEDs and artificial photosynthesis, which are strongly related to our daily life, and to construct the scientific basis of their operation mechanisms, through integrating state-of-the-art material and device modification technologies and data-driven science, into the visualization techniques of semiconductor operation processes using optical spectroscopy and magnetic resonance techniques that are promoted by the principal investigator. With a strong team structure that integrates different fields of physics, chemistry, and information science, we aim to produce world-leading research results and explore new frontiers of knowledge.

Outline

By identifying the factors that affect the defects in through-silicon via (TSV) electrodes, which are responsible for signal transfer in 3D stacked semiconductors, we will optimise the manufacturing process for TSV formation. Extracting the factors that cause defects from multi-scale measurement data, a device performance function is defined and used to estimate the optimal parameters for the main processes of TSV formation (RIE, CVD, plating, etc.). The effectiveness of this methodology will be demonstrated through its application to visual prostheses, and its application to other semiconductor manufacturing processes will be investigated.

Outline

A new two-photon microscopy system will be developed using time-multiplexing, multiline and spatiotemporal focusing techniques, multifocal planarisation and holographic multipoint focusing. Using this microscope, we will visualise central nervous system activity during walking and attempt to elucidate the gait control mechanism. A method for analysing the large-scale data obtained will be developed, and a theoretical model of gait locomotion will be constructed through verification by artificial changes in neuronal activity induced by light stimulation.

In cancer immunotherapy, the lack of technology to measure cell-cell interactions at the single-cell level has become a bottleneck in improving therapeutic efficacy. To address this, we will observe the individual interactions between a single immune cell and a single cancer cell at a large scale using photoresponsive cell anchoring surfaces. Through image recognition analysis of time-series images, immune cells and cancer cells will be automatically classified based on the characteristics of cancer cell cytotoxicity. The classified cells will then be selectively collected, and their gene expression will be analyzed to identify genes related to therapeutic effects, contributing to solving the challenges of cancer immunotherapy.

Outline

As the increasing power consumption accompanying the advancement of the information society becomes a societal issue, the development of energy-efficient magnetic device materials is gaining attention. However, the nanoscale size and the high-speed operation of cutting-edge materials create obstacles in material development, as it becomes difficult to observe their behavior during operation. In this study, we aim to construct a digital twin of materials by visualizing the spin structures of magnetic devices with high spatiotemporal resolution using advanced measurement techniques, and reconstructing them through simulations. This will help uncover the origins of material properties and accelerate the development of innovative magnetic devices.
