The lab develops core technologies for scanning electron microscopes (SEMs) through industry-academia collaboration.

AboutAbout the lab
Improving SEM performance and creating new applications.
The Hitachi High-Tech Advanced SEM Technology Lab studies core technologies for scanning electron microscopes (SEMs) in industry-academia collaboration with Hitachi High-Tech.
SEMs can observe fine structures at the nanometer scale, and samples are easy to handle, so they are used in a wide range of fields, including nanotechnology and biotechnology.
The lab tackles more difficult challenges in core SEM technologies such as electron guns and signal detectors, aiming to develop technologies that achieve high resolution, high precision, and high throughput.
The lab says it aims to apply the results of the industry-academia collaboration between Hitachi High-Tech and the University of Tsukuba to product improvement, and to develop new SEMs and products that apply them.
