SUMCO wishes to express its sincere sympathy to all those affected by natural disasters in 2018, including the 2018 Hokkaido
Eastern Iburi Earthquake and torrential rains in western Japan, and pray for a speedy recovery in the areas affected.
SUMCO’s Chitose Plant (Chitose City, Hokkaido Prefecture) was also exposed to Intensity 6 Lower tremors during the Hokkaido
Eastern Iburi Earthquake, and while no injuries were incurred, the damage included a partial shutdown of the production line.

We also ensure the thorough management and handlingof harmful chemical substances and waste, and make every
effort to minimize the environmental risks resulting from ourbusiness activities.

Despite these challenges, SUMCO’s employees continued with all-out recovery efforts and SUMCO received enormous support
from customers, suppliers and other business partners. As a result, regular operation was restored in the month following theearthquake. The lessons gained through this most recent earthquake will be utilized to make improvements to the SUMCO Group’sbusiness continuity plan (BCP).

SUMCO Products that Support Our Lives
SUMCO manufactures silicon wafers, a key material in semiconductor devices. Semiconductor devices that use SUMCO’s silicon

wafers support our lives in a variety of ways, from electronic devices around us such as mobile phones, computers, smartphones

Trains, Bullet Trains

and digital appliances to automobiles, medical equipment, industrial machinery control units, as well as the control of public
transportation and infrastructure.

Automobiles

Smartphones, Tablets,
Computers

Numerous semiconductor devices
are at work inside motor vehicles. An
extremely high level of quality andreliability is required for silicon wafers
to be used for motor control in electricvehicles (EV) and hybrid vehicles (HV/
PHV) and for driver assistance systems
such as self-driving, automatic braking
and lane-keeping functions.

Data Centers(Server Rooms)

Large numbers of cutting-edge semiconductors are used in telecommunications equipment including logic
chips to run various applications suchas email and internet browsing, image
sensors and memory to store data.
Every year, the functions of these semiconductors become more sophisticated, and they are made using SUMCO
silicon wafers.

IoT/ Digital Appliances

With smar tphones and computers
becoming increasingly sophisticated,vast quantities of data in the form of
high-quality photographs and videos are being processed in the clouds
and stored in data centers. SUMCO’
high-precision leading-edge siliconwafers are used for the memory andlogic chips that store and process enormous volumes of data.

IoT devices, including wearable devices and digital appliances that can be
operated via smartphone, are connected to the internet.
SUMCO’s silicon wafers are used in
the data communication semiconductors and sensors equipped in thesedevices.

Devices called power semiconductors areused to control electric power. These devices
are technically complex and require reliable
control of large amounts of power and powersaving performance, making this a specialized
field.
Power supply control for heavy electricmachinery, in particular, such as electric trainsthat use power of over 1000V, requires special
know-how for the silicon wafers, as well.

Power Generation
Facilities and Public
Infrastructure

Digi t al c amer a s recor d precious
memories while securit y cameras
protect public safety. As the“eye”ofthese cameras in taking videos andimages, semiconductor devices called
image sensors are used. The highquality and reliability of these image
sensors are also supported by SUMCO’ssilicon wafers.

In the medical field, medical equipment hascontinued to evolve, with the advent of highprecision diagnostic imaging equipment andsurgery robots capable of precise control.
A large number of silicon wafers are usedin these medical devices, and the siliconwafers that serve as their substrates require
high reliability, especially as human lives are
involved. SUMCO’s silicon wafers contribute to
the advance of medicine.

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.

Message from an Outside Director

I believe that the robust discussions that take place in the Board of
Directors are characteristic of SUMCO’s governance system.

Masahiro Mitomi, Outside Director
Q1. From your standpoint as an Outside
Director, moving forward, how do you
expect SUMCO to pursue the promotion
and development of its business in themedium-to-long-term, and how do you
envisage your involvement?
To promote and develop its business activities going forward in the medium-to-long
term, I think it is important for SUMCO to continually implement
initiatives aimed at achieving the SUMCO Vision. I also think that torespond flexibly to changes in the industry, SUMCO should with-

draw from fields in which it lacks strengths and opportunities, andQ3. In recent years we have seen heightened interest andexpectations pertaining to ESG (environment, social andgovernance). How do you feel SUMCO, for its part, needs to
respond to this trend?
I believe SUMCO has incorporated ESG perspectives in the courseof efforts to achieve the SUMCO Vision and its CSR policy. Accordingly, I think it will be important to push forward in a thoroughlyhonest fashion to achieve the vision and policy, and develop thehuman resources capable of doing so at multiple levels within theorganizational hierarchy.

Q1. What points do you give the greatest priority to in terms of quality at
SUMCO?
Naturally we need to make sure what we produce meets therequired specifications of the product, but it is also importantwhen SUMCO products are used, they adequately fulfill the
expected function.
Even if a product meets standards, if it deviates from ournormal level of quality, we treat it as a non-conforming piece,

In recent years, the importance of risk assessments has attracted increased attention, and SUMCO is no exception. We
have taken proactive steps in this area such as holding seminars
and briefing sessions on initiatives to promote effective useof failure mode effect analysis (FMEA). By addressing quality
risks through adequate risk assessments, we aim to attain Zero
Excursion and Zero Defect.
Q2. What challenges or fulfilling experiences have you
faced in promoting quality control across the entire Group,
including overseas?
Overseas, the cultural background of language can differ,and even the same expression can be interpreted differently,
which can cause problems as we pursue our work. Similarly in
our Japan operations, due to differences in product types orprocesses, even using the same words can produce a subtly
different impression. We pursue quality control initiatives in
the hope of understanding and overcoming those differences, and praising one another’s efforts when our shared goals
are met.
I would count providing support for IATF16949 certificationin Indonesia and introducing the SUMCO method of change
management procedures among our achievements in termsof quality improvement initiatives. We are working with thehelp of overseas departments to develop quality assurance
systems that span the entire SUMCO Group.

mation sharing are made.

When I experienced trouble during pregnancy, or when I have needed to take time off work at short notice when my childhas fallen ill, my supervisor and colleagues have responded with flexibility, and I am extremely grateful for their support.
Moreover, after finishing childcare leave, I was placed back into the same department and I was able to resume work without a lot having changed. Thanks to that, I was able to get used to my current lifestyle in short order. My application for shortworking hour was also accepted without hesitation and I have been given consideration in terms of assigned workload andother aspects. I think these have also made it a truly pleasant workplace.

The committee, attended by the Chief Health Officer and other executives, reports on Group-wide activities related to safety,
health and hygiene management as well as major work-related
accidents, and also reviews and approves safety and health-related issues and targets to be addressed in the following fiscal
year.
Additionally, each plant defines policies and objectives related to safety and health for each fiscal year based on company-wide safety and health issues, and engages in daily activities
to achieve those objectives.

Armed with a lot of energy and some 5S techniques, themembers of SES went ahead to help the foodbank reorganise the collected food into the various food groups as well37

as put it in date order to ensure that the shortest sell by dates mission
In SES we decided, as part of honouring SUMCO’statement“to be a good neighbour in our community”, to
do something that would help people in our community.
We chose to volunteer at a foodbank as this should help alarge portion of some of the most vulnerable people in thecommunity. Foodbanks are volunteering organisations
that collect donated food and distribute it to the poor andneedy.
Their services are in more demand than ever due to theoverall economic climate. SES worked closely with a foodbank in South London, about 7.5km away from our office,to find out when was the best time to support them.
Foodbanks tend to receive a large amount of donationsin the run-up to Christmas, but these donations have tolast for most of the following year. SES agreed to send two
teams of volunteers on one of the foodbank’s busiest daysof the year for donations. At this time the few members ofstaff are overrun with donations and struggle to keep thing

as they would never have had the time to do it themselves

food was used first and that nothing went to waste.
The foodbank was exceptionally pleased with SES’s helpduring such a busy period. SES members brought some of
their own food to donate to the foodbank as well as donations to ensure that the foodbank was able to continue supporting the local community when the Christmas stocks
had been used up.
All SES members thoroughly enjoyed the experience.
