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.
