DISCO Corporation (Head Office: Ota-ku, Tokyo; President: Kazuma Sekiya) has decided to invest approximately JPY 14 billion to build a D-Zone as an extension in addition to C-Zone, which is currently under construction in A-Building of Kuwabata Plant (Kure City, Hiroshima), where precision processing equipment and precision processing tools are being manufactured.

Purpose of D-Zone Extension

Production system enhancements to meet the growing demand for precision processing tools
With the development of the IoT and self-driving technology as a backdrop, the number of data centers and sensors is increasing. Due to advancements such as this, the utilization of semiconductors and electronic components is expected to continue to grow in the future, also causing demand for precision processing equipment*1 and precision processing tools*2 to continue to grow.
In such a market environment, DISCO has already decided to construct the Nagano Works Chino Plant and expand the production line of manual dicing saws at Chino Plant (announced on July 31, 2017) for the enhancement of the precision processing equipment manufacturing system. Despite that C-Zone in A-Building of Kuwabata Plant is currently being extended (announced on April 28, 2016), DISCO has decided that the further enhancement of the manufacturing system is necessary to meet the expected increase in demand, and will add the D-Zone. Furthermore, DISCO aims to reduce total construction costs by making the extensions below in continuation from C-Zone.

※1 Precision processing equipment: Machines for cutting, grinding, or polishing silicon wafers.
※2 Precision processing tools: Tools mounted in precision processing equipment for cutting or grinding, and frequently replaced consumables.

Overview and Construction Schedule
