CEO Kentaro Fukushima


SHIBA R&D CO., LTD was founded in July 1980 for the purpose of selling processing machines. We have been selling processing machines of silicon wafer and photomask substrate as well as offering engineering works in various fields. Based on the original know-how accumulated through the experience of supplying processing machines for crustaceous materials, we established a factory in Yokosuka City, Kanagawa in June 1995 for OEM machining service of precise/difficult processing with our processing machines. Since then, we have developed unique processing techniques for hard-brittle materials such as glass, silicon, and ceramics, developed jig and tools and processing machines, and diversified product lineups.
