Sumitomo Heavy Industries, Ltd. (Head Office: Shinagawa-ku, Tokyo; Representative Director, President and CEO: Shinji Shimomura; hereinafter “SHI”), has today announced the integration of its laser business of the Mechatronics Div. (*) with Sumitomo Heavy Industries Ion Technology Co., Ltd. (Head Office: Shinagawa-ku, Tokyo; President and Representative Director: Mitsukuni Tsukihara; hereinafter “SMIT”, a fully owned subsidiary of SHI responsible for the ion implanters business), with the new operation set up to start on January 1, 2025.

[Background to the Business Integration]
In the Medium-Term Management Plan 2026, which started in 2024, we have designated the “semiconductor field” as one of the priority investment areas that will drive our growth, where we are working to promote the development of next-generation models designed for market expansion and change, as well as to expand the sales channels on a global basis.
The core product in the laser business of the Mechatronics Div. is laser annealing equipment, which is primarily used in the production of power semiconductors. In this field, we are a leading player both in Japan and overseas, with
SMIT being a leading supplier of ion implanters used at the forefront of semiconductor production.
Annealing equipment and ion implanters are closely linked in semiconductor production. Integrating these two businesses will enable us to offer both types of equipment in a single company and give our customers a new enhanced solution. Furthermore, by combining the management resources of SHI and SMIT, we will expand our business range globally and contribute to the growth of the semiconductor industry.

(*) As well as laser equipment, the Mechatronics Div. handles motion controllers and other control components for industrial machinery, as well as actuators such as the precision XY stage for semiconductor production equipment.
