マ ネジメント

SUMCO Products That Support
Our Lives
SUMCO manufactures silicon wafers, which serve as the core and base of semiconductor devices.
Semiconductor devices that use SUMCO’s silicon wafers as their main materials support our lives in a variety ofways, from electronic devices around us such as mobile phones, computers, smartphones, digital appliances, toautomobiles, medical equipment, control units for industrial machines, as well as the management of public
transportation or infrastructure.

Polished Wafer

The production of silicon wafers is generally divided into two processes: the monocrystalline silicon process and the wafer process. In the
monocrystalline silicon process, polycrystalline silicon is melted to produce monocrystalline silicon ingots. In the wafer process, these
monocrystalline silicon ingots are sliced into wafers, which are then polished and cleaned to create a flat, mirror-like surface.

Smartphones, Tablets,
Computers

Data Centers(Server Rooms)

Large numbers of cutting-edge semiconductors
are used in telecommunications equipments,
including logic chips to run various applicationssuch as e-mail and internet browsing, sensors
for taking photographs, and memory to store
photographs and other data. Every year thefunctions of these semiconductors become
more sophisticated, and they are made using
SUMCO silicon wafers.

With smartphones and computers becoming
increasingly sophisticated, vast quantities ofdata in the form of high-resolution photographs
and videos are being processed in the cloud andstored in data centers. SUMCO’s high-precision,leading-edge silicon wafers are used for memory
and logic chips that store and process enormous
amounts of data.

CamerasDigital cameras record precious memories whilesurveillance cameras protect public safety. As the“eye” of these cameras in taking videos and images,
semiconductor devices called image sensors areused. The high quality and reliability of these image
sensors are also supported by SUMCO’s siliconwafers.

IoT / Digital Appliances
IoT devices are devices that are connected to
the Internet, including wearable devices anddigital appliances that can be operated via
smartphone. SUMCO’s silicon wafers areused in semiconductors and sensors thatenable data communication by these IoT
devices.

Automobiles
Numerous semiconductor devices are already atwork inside motor vehicles. An extremely high level ofquality and reliability is required for silicon wafers to
be used for motor control in electric vehicles (EV) andhybrid vehicles (HV/PHV) and for driver assistancesystems such as self-driving, automatic-braking, andlane-keeping functions in driver assistance systems.

Smart Card Devices

Trains, Bullet Trains
Devices called power semiconductors areused to control electric power. These aretechnically complex devices, making this a
specialized field. Power supply control forheavy electric machinery, in particular, suchas electric trains that use power of over 1000
V, requires special know-how for the siliconwafers, as well.

* Wastewater from the Yonezawa Plant is discharged to a public sewer and therefore falls under the category of “wastewater discharged into rivers after treatment at sewage
plants” under the Sewerage Law. For this reason, the regulation value for fluorine compounds is 8 mg/l.
