• Wafer

We offer a range of particle management products in various sizes. We can provide them according to your specifications and requirements.

【Monitor Wafers】 Used for process checks and particle checks. Regularly monitor the results of daily processes and provide feedback on conditions (recipes) if any issues arise. They are also used when conducting regular particle checks within the equipment. 【Test Wafers】 For testing purposes, such as wafers that are run in advance. There are cases where only the problematic processes are run without going through the full process. We handle various particle management products for monitoring and testing purposes.

• Wafer

Support for small lots is also available! A wide lineup of epitaxial wafers.

We will be exhibiting at the J AGRI (J Agri) / Agricultural Materials EXPO held at Gran Messe Kumamoto from May 22 (Wednesday) to May 24 (Friday), 2024. 【Booth Number】: B1-43 Outdoor Exhibition Area Japan's largest comprehensive exhibition for agriculture and livestock, Agricultural WEEK, will be renamed J AGRI starting in 2024. This is a place where you can actually see, touch, and compare products. At our booth, we will showcase our lightweight resin flooring boards "JULIGHT / SUPER JULIGHT / RAKURAKUBAN" along with new products. Starting with the agricultural-specific flooring board "RAKURAKUBAN," which can be easily laid in various scenes such as around greenhouses, agricultural work sites, temporary parking lots, for the movement of agricultural machinery and light trucks, and for protecting truck beds, there are various ways to use the lightweight resin flooring boards "JULIGHT / SUPER JULIGHT series." We offer a variety of sizes and protrusion shapes tailored to customer needs, and they are lightweight enough to be carried by hand, with excellent impact resistance, as well as superior water resistance, weather resistance, and durability, providing outstanding features not found in plywood or steel plates. We sincerely look forward to your visit.
