Grinding Technology Japan 2023 (GTJ2023) March 8 (Wed.) - 10 (Fri.), 2022
Makuhari Messe


  We will hold Grinding Technology Japan 2025 (GTJ2025) for 3 days from Wednesday, March 5, to Friday, March 7, 2025, at Makuhari Messe in Chiba Prefecture. GTJ, which specializes in ‘exhibitions focusing on tool manufacturing and grinding technology’ and ‘exhibitions where you can find answers for your site,’ will be held for the fourth time, after first being held in 2019.
  Automation and unmanning are also making remarkable progress in the grinding industry. On the other hand, know-how remains an important element. At GTJ2025, in addition to providing the latest information on grinding and tool manufacturing technology, we will also provide information on skills and know-how. As in the past, we will hold various opportunities for discussion, including the Grinding Concierge. We cordially invite everyone involved in tool manufacturing and grinding to attend GTJ2025 and take part in the discussions.

Held at the same timeSiC, GaN Machining Technology Exihibition 2025

  The “SiC,GaN Machining Technology Exihibition 2025” will be held concurrently with “Grinding Technology Japan 2025,” an exhibition specializing in grinding technology.
  To realize a carbon-neutral society by 2050, it is essential to promote electrification of the mobility industry (EV) as well as the usage of renewable energy as a main power source, and the spread of highly-developed power electronics technology using advanced power semiconductors such as SiC and GaN has become the most important factor.
  Therefore, mass production and cost reduction of advanced power semiconductor wafers are strongly desired. However, these materials are extremely hard and resistant to heat and chemicals. Processing them is extremely time-consuming, and reducing the high processing cost is an urgent issue.
  “SiC,GaN Machining Technology Exihibition 2025” is an exhibition for engineers and technicians involved in the processing of these advanced power semiconductor wafers, as well as for advanced power semiconductor researchers and those who wish to learn more about them. We believe that exhibitors will be able to provide the best answers with the latest technology and knowledge to visitors with such issues. “SiC,GaN Machining Technology Exihibition 2025” will feature slicing, grinding, polishing, and CMP processing technologies related to advanced power semiconductor wafer processing, as well as a variety of wafer evaluation technologies.
  “SiC,GaN Machining Technology Exihibition 2025” will be participated in by the Japan Society for Abrasive Technology, which focuses its research on abrasive grain processing, and the Japan Society for Applied Physics Advanced Power Semiconductors, which focuses on advanced power semiconductors such as SiC, GaN, and diamond, as “special cooperation” organizations.
  There is no argument that in addition to technology and skills, theoretical underpinnings are important for advancing advanced power semiconductor wafer processing. At the “SiC,GaN Machining Technology Exihibition 2025,” the Japan Society for Abrasive Technology and other cooperating organizations will provide explanations of processing theory from an academic standpoint and talk about the future of semiconductor wafer processing technology.
