Taniguchi Lab
Machine-translated · View original
The lab studies making nanoscale three-dimensional structures and transferring them by pressing.
AboutAbout the lab
Making and copying nanoscale 3D shapes.
The Taniguchi Lab researches ultrafine fabrication technology at the nanometer scale.
It focuses in particular on technology for making three-dimensional shapes at the nanometer order.
The lab studies techniques for making three-dimensional nano-stamps (molds), and nanoimprint, in which the stamp is pressed to transfer its shape.
Fabrication uses electron beam and ion beam technology, and the resulting molds are replicated into resin and other materials.
Key terms
- Nanoimprint
- A fabrication technique in which a mold with nanometer-sized relief is pressed against resin or other materials to transfer its shape.
- Electron beam lithography
- A technique that uses an electron beam to draw fine patterns and create nanoscale shapes.
- Roll nanoimprint
- A nanoimprint method in which the mold is made into a roll to transfer nanoscale shapes.

ResearchResearch themes
Nanotechnology is a foundational technology that supports the advanced information society. The lab places particular emphasis on fabricating three-dimensional shapes, which are expected to be a next-generation technology, and studies the making of three-dimensional nanomolds, nanoimprint technology that presses them to transfer their shapes, and its applications.
*Illustrative imageFabrication of three-dimensional nanostructures
Using electron beam lithography with varying acceleration voltage, the lab has achieved a depth resolution of up to 5 nm. It made three-dimensional nanomolds with depth varying at scales of 100 nm or less, and was able to transfer and replicate their patterns.
*Illustrative imageResearch on roll nanoimprint
The lab studies roll nanoimprint, in which the mold is made into a roll. Its work includes transfer using replica molds, high-speed transfer, and lifetime evaluation of the mold's release properties.
