Sumitomo Osaka Cement : ​ ​About increasing production capacity of semiconductor manufacturing equipment parts ESC

Sumitomo Osaka Cement Co., Ltd. (President: Hironori Morohashi, Headquarters: Chiyoda-ku, Tokyo) is a major component of semiconductor manufacturing equipment at the Ichikawa office (Ichikawa City, Chiba Prefecture) and the Funabashi Plant (Funabashi City, Chiba Prefecture). We are pleased to inform you that we have started construction to increase the production capacity of ESC (Electrostatic Chucks *).

The semiconductor manufacturing equipment market is expected to continue to grow in the future as global demand for semiconductors, especially for hyperscale data centers and 5Gsmartphones, increases due to the accelerated transition to the data society.
ESC (Electrostatic Chucks), which is the main product of our advanced materials business, has the characteristics of high purity, high heat conduction, high withstand voltage, and high durability using ultra-high purity SiC (silicon Silicon)ultrafine particles as raw materials. , It is widely used as a main component of semiconductor manufacturing equipment. We have been gradually increasing the ESC production capacity from FY2016in order to respond to the growing demand for semiconductor manufacturing equipment, but the rapid expansion of semiconductor demand from FY2021and the recent ESC Due to the complexity of the design structure, the operating rate of production equipment has remained at a high level.
With this construction, we will double the production capacity of the conventional product, meet the demand for semiconductor manufacturing equipment, which is expected to grow further in the medium to long term, and produce and ship products that meet customer needs in a timely manner. We will expand our business and strengthen our competitiveness in the market through the stable supply of high-quality products.
