In the precise world of next-generation chip fabrication, defects are often measured in nanometers, or one-billionths of a meter. This makes the demand for accurate polishing systems capable of mass production especially critical as the industry shifts toward complex 3D-stacked designs.
Japan’s BBS Kinmei Co., Ltd., based in rural Ishikawa Prefecture, produces polishing machines not only for the semiconductor industry but also for demanding use cases such as renewable energy systems and optical films. President Ryunosuke Kawahara draws inspiration from the region’s rich lacquerware-making tradition, or urushi-nuri. “I think that the biggest characteristic of the area is that it is a home of craftsmanship. Local people have ideas and designs that are integrated into the area’s industry, elevating the overall level of monozukuri,” he says. In today’s competitive chip-making landscape, Kawahara recognizes the need for efficient machines. “Our edge polisher machine excels in shape controllability, which creates optimal edge shapes and reduces variation, making it an indispensable part of modern semiconductor manufacturing processes,” he said. Over time, BBS Kinmei worked to build a strong production base in Japan as the country’s semiconductor industry rapidly grew. Now, with over 60% of orders coming from China, along with sales to other regions such as Europe, South Korea and Taiwan, BBS Kinmei is ready to make an impact globally. “Regarding international expansion, we believe that a flexible international strategy is necessary, especially in the semiconductor and precision machinery fields, where markets are changing rapidly,” Kawahara said.
