Completion of Building Construction at Kuwabata Plant (Zone C, A-Building)

DISCO Corporation, a semiconductor manufacturing equipment manufacturer (Headquarters: Ota-ku, Tokyo; President: Kazuma Sekiya), has completed construction of a new building (Zone C, A-Building) with a seismically isolated structure at Kuwabata Plant (Kure City, Hiroshima), where precision processing equipment*1 and tools*2 are manufactured. The floor space in the existing building (Zones A and B, A-Building) has been expanded as a result of this construction, and the production space will be increased approx. 1.5 times.

Purpose of Zone C Construction in A-Building, Kuwabata Plant

Enhancement of Precision Processing Tool Production System and BCM*3 Support

The semiconductor and electronic component markets are expected to continue expanding in the future based on the development of IoT, AI, self-driving technologies, and installation of multiple cameras on smartphones. Demands for DISCO’s precision processing equipment and tools are also expected to increase accordingly. DISCO has two production sites, Kuwabata Plant and Kure Plant, in Kure City, Hiroshima. Precision processing equipment and precision processing tools are mainly produced in Kuwabata Plant and Kure Plant, respectively. By allocating a part of the production space in Zone B, Kuwabata Plant, for which construction was completed in January 2015, for precision processing tools, a second production site was established to improve BCM support. Moreover, by making Zone C in A-Building, Kuwabata Plant, for which construction was completed in January 2019, a production space for precision processing tools, DISCO will achieve further enhancement of the production system and BCM support, as well as more effective production through the promotion of automation.

*1 Precision processing equipment: Equipment used for cutting, grinding, and polishing silicon wafers, etc.
*2 Precision processing tool: Tools mounted on precision processing equipment which performs the cutting, grinding, and polishing. These are consumables and must be replaced frequently.
*3 BCM: Business Continuity Management
