Applications
Our products underpin development of various cutting-edge technologies.
For example, calcium fluoride, which has strong laser durability,
is used in semiconductor lithography equipment and contributes to semiconductor manufacturing.
And our high quality X-ray devices are playing an indispensable role in security systems such as airport baggage scanners.
Optical Crystal Supporting Semiconductor Manufacturing
Our CaF2 (calcium fluoride) has high optical transmittance over a vast wavelength range from the vacuum-ultraviolet region to the near-infrared region and excellent durability against ArF, KrF, and other excimer lasers.
For this reason, our product is used in equipment that occupy an important place in the semiconductor manufacturing industry, such as semiconductor lithography equipment and excimer laser equipment. It is also used in broadcast TV cameras and astronomical telescopes.

A semiconductor lithography equipment is a machine that creates CPU and memory circuit patterns on Si wafers. Like a photo, it projects a mask image with an etched circuit pattern on the wafer. As a circuit pattern is tens of nanometers, it is further reduced and projected using an ArF laser, which is an ultraviolet laser, as a light source. Another method for higher resolution is to fill the gap between a lens and a wafer with pure water (immersion method). Our CaF2 is used in lenses for these apparatuses.
