Fulfilling our commitment

to ensure stable supply

through the collective strength

of the ROHM Group

Stable supply

The ROHM Group assesses market conditions to fulfill its

commitment in supplying products that customers demand.

All manufacturing processes are managed in-house using a

vertically integrated production system. Compared to

traditional manufacturers that do not own fabrication

facilities or foundry manufacturers, our system is not as

susceptible to external factors.

ROHM strives to ensure a stable supply to customers, for

example by establishing a Business Continuity Management

(BCM) system that includes multi-site production and

maintenance of safety stock in order to flexibly respond to

natural disasters and other unforeseen events.

Achieving high quality

in all processes

High quality

ROHM considers ‘quality first’ as its company

objective and unwaveringly pursues this goal.

All processes, from production, from

development, design and wafer manufacturing

to sales and service, are carried out within the

group using a vertically integrated production

system, and activities are implemented in each

process to improve quality. This also results in

excellent traceability and establishes a system

that ensures worry-free use of our products.
