Decision to Construct a New Building at Nagano Works Chino Plant
DISCO Corporation, a semiconductor manufacturing equipment manufacturer (Headquarters: Ota-ku, Tokyo; President: Kazuma Sekiya), has decided to invest approx. JPY 17.5 billion to construct a new seismically isolated building at Nagano Works Chino Plant (Chino City, Nagano).
Purpose of New Building Construction at Chino Plant
With the introduction of fifth generation (5G) communication systems accelerating, the semiconductor and electrical components markets, including the development of IoT, self driving systems, and remote medical technology, are expected to expand. The demand for DISCO’s precision processing equipment※1 and tools※2 is also expected to increase accordingly. In response to the expected growth of these markets, DISCO is expanding※3 Kuwabata Plant (Kure City, Hiroshima). However, it was determined that further enhancement of the production system will be required.
In addition, most of the precision processing equipment and tools are currently produced in Kure and
Kuwabata Plants, which are located in Hiroshima. Seismically isolated structures have been adopted in the
buildings at both plants, and construction to ensure an independent water source has been conducted to
protect against future water outages. However, the distance between the two plants is only about 10 km.
Therefore, in order to prevent a situation where both plants cannot function should a disaster affect the
entire area, resources must be divided further.
In consideration of these factors, DISCO has decided to begin construction of a new building at Nagano
Works Chino Plant.
※1 Precision processing equipment : Equipment which performs cutting, grinding, and polishing of silicon
wafers, etc.
※2 Precision processing tools : Tools which are installed on precision processing equipment and perform
cutting, grinding, and polishing. Precision processing tools are consumables and must be replaced
frequently.
※3 News Release regarding the Completion of
Zone C Construction and the Beginning of Zone D Construction in Building A, Kuwabata Plant (January 31,
2019)
