Functional Integrated Devices Lab
Machine-translated · View original
A lab that creates a new generation of semiconductor devices using silicon nanostructures.

AboutAbout the lab
Taking on the development of next-generation nanoelectronic devices!
Makihara Lab researches the semiconductor technologies that underpin the advancement of electronics.
The lab's research spans everything from materials science to the processes used to fabricate devices.
The lab works on incorporating nanostructures such as silicon-based quantum dots into devices, improving transistor performance, and developing devices that combine light and electronics as well as new types of memory.
Through joint research with overseas research institutions and presentations at academic conferences, students can develop the abilities expected of independent engineers and researchers.
Key terms
- Quantum dot
- An extremely small semiconductor particle, nanometers in size. It confines electrons inside and shows properties different from those of a large crystal.
- MOS transistor
- A transistor with a structure of stacked metal, oxide film, and semiconductor. It is a basic component used to make computer chips.
- Gate insulating film
- In a transistor, a thin insulating film between the semiconductor and the electrode (the gate) that switches the current on and off.

ResearchResearch themes
To contribute to advancing semiconductor technology, especially silicon nanotechnology, the lab conducts cross-cutting research ranging from materials science to process integration and device fabrication technology. Alongside improving the performance of silicon-based thin-film transistors and fine-scale MOS transistors, it focuses on developing devices that integrate photonics and electronics, as well as memory with new functions.
*Illustrative imageDevices Incorporating Nanostructures
The lab integrates silicon-based nanostructures into MOS devices to advance the functions of the devices themselves. It also works on applications to intelligent information processing devices that operate with a small number of electrons or photons.
*Illustrative imageMaterials and Processes for Integrated Devices
Using high-resolution spectroscopic analysis and probe microscopy, the lab advances the materials science of high-k gate insulating films and gate-all-around (GAA) transistors. It also develops process technologies for fabricating such functional thin films with control at the level of individual atomic layers.
*Illustrative imageInterface Control and Thin-Film Devices
Aiming for devices that adopt new operating principles, new materials, and new processes, the lab focuses on two-dimensional crystals of group IV semiconductors. It improves techniques for observing the film growth process in situ and controlling it precisely, as well as techniques for fabricating devices.
