Interview video: Manufacturing innovation through simulation
Read the text here
We are developing computer simulation technology for the manufacturing processes and electrical properties of semiconductor devices. We're utilizing them for the R&D of cutting-edge memory devices. This technology is called TCAD, or Technology CAD. Research on complex element structures and new principles of operation is also advancing due to the high integration of semiconductor memories. BiCS FLASH™ has a complex structure, so analysis by semiconductor simulation is indispensable. With simulation, there's no need for experimenting as we can predict the results by calculation. We need to utilize simulation technology to achieve a digital twin, where synergy from linking real-world experiments and simulation on cyberspace actualizes.
Our company has highly-skilled engineers in process and device technology as well as circuit and system design technology. These experts have excellent cooperation and mutual understanding, which adds to our strengths. TCAD engineers are also working closely with experts in other technical fields to carry out research and development. That way, we'll be able to see things from a different angle than our expertise. Others can also see how to utilize the technology that we have and bring up new ideas. So, in that sense, I think it's very important to have discussions and boost cooperation with people from different fields.
Contribution to the world 10 years from now
Computational science simulation has evolved from a tool for understanding and explaining phenomena to one that predicts the physical properties and functions of new materials. Manufacturing innovations that make full use of these computational science simulations are taking place in various industrial fields. KIOXIA conducts research and development to bring a world that creates new value and fun by connecting records as digital signals with people, things, and time through the development of semiconductors that use cutting-edge TCAD and computational science simulation technology.
