Electronic and semiconductor device field
Technological innovation in electronic and semiconductor devices, which form the foundation of modern industry, has been supported by the miniaturization of wiring technology in large-scale integrated circuits. As we move into the 7nm generation, many challenges remain in achieving further miniaturization, and the challenges in the constituent elemental technologies must be resolved. To date, our laboratory has developed a technology for depositing high-melting-point thin film materials at low temperatures, which was previously difficult, and is conducting research and development aimed at improving the thermal stability of fine wiring materials and diffusion-blocking films.
