ROHM's Strengths
Since its founding more than 60 years ago, ROHM has embraced the mission of contributing to cultural advancement through its products. Over this time, we have cultivated two core strengths: Customer Orientation and Cutting-Edge Technology.
By absorbing customer needs and swiftly proposing truly necessary solutions, while combining unconventional development capabilities with manufacturing expertise, ROHM responds to market and customer demands.
Supporting these strengths are IDM (Integrated Device Manufacturer), Integral Technologies, and Power / Analog Technology.
ROHM will continue to evolve and deepen these strengths, building on what we have cultivated since our founding, and strive for ongoing growth.
Employees’ Perspective
Customer Orientation is the Key to Business Growth;Deep Trust With Customers Leads to Innovative Products
As Sales Manager of the Automotive Group at ROHM Semiconductor Taiwan Co., Ltd., I am responsible for promoting and selling ROHM products to customers in Taiwan. As someone who works on the front lines of sales, listening to the voices of our customers is of utmost importance to me every day. Recently, there was a case where a component manufactured by ROHM, despite being in mass production with proven performance, was not compatible with a specific model. So, we provided flexible and precise solutions, including advice on circuits and layout, taking into account the customer’s unique design, and successfully guided the product to market launch.
Our customers are also the driving force behind our growth. Understanding existing customer needs and anticipating new ones is the key to business growth. This customer-oriented approach also leads to the establishment of trust with customers and brand loyalty.
Safety is the most important mission in the automotive industry. I can confidently say to our customers in Taiwan’s automotive industry that “Quality is ROHM’s top priority at all times.” Through ROHM’s cutting-edge semiconductor technology, I believe that we can contribute to environmental considerations and improvements in automotive convenience and safety by providing our customers with the most innovative products. I hope that more and more cars equipped with ROHM products will be seen on roads around the world.
Solving Various Production Process Problems and Creating an Efficient Production System Through the Promotion of Quantum-Technology Based DX
I am striving to improve production efficiency for the overall ROHM Group through the use of digital technology. Complex constraints and long lead times are issues that are particularly relevant in the semiconductor wafer production process.Therefore, we are taking on the challenge of optimizing production scheduling through quantum technology in partnership with Quanmatic Inc. This is an effort to eliminate semi-finished products and reduce lead times through mathematical modeling of workplace knowhow and the automation of production planning, which formerly relied on individuals. By combining this with the calculation of the semi-finished product saturation lot number* we aim to establish a production system that minimizes the number of semi-finished lots and maximizes the strengths of IDM. With verification testing, we determined that there were issues with ascertaining lot location and communication, but were able to confirm that it is possible to operate in a way that maintains equipment utilization rates through the use of monitors installed on shelves and other activities.
In the future, we will expand the use of quantum technology to total solutions, not only pre-manufacturing processes but also post-production processes, and digitally reproduce plants throughout the world, in order to optimize capital expenditures, make bottlenecks visible, and achieve other goals. would also like to contribute to increased corporate value through a focus on the training of DX staff who possess knowledge of both digital technology and operation divisions.
* Number of lots that do not lead to greater production volume even if the number of lots of semifinished products is increased.
Customer Joy and ROHM’s “Integral Technologies” to Solve Global Social ProblemsI
I am in charge of marketing analog front end (AFE) products that amplify the processing of minute signals from sensor Through the Promotion of Quantum-Technology Based DX elements and other components.
We uncover the latent problems of customers through close communication and propose product specifications and solutions to address those challenges, while also developing product plans. We received a consultation from a customer who is experiencing difficulties because they have to change the circuit boards for each product output specification, which doubles the effort required for evaluation and certification processes. At that point, we coordinated ROHM’s analog technology and process technology to propose a foundational design that can accommodate different product specifications using a common circuit. Through repeated consultations with our customers, we successfully brought the product to market. As a result, not only was the customer’s workload reduced, but it also led to the effect of halving the product inventory, which I remember that the customer was very pleased with. In this way, we believe that our development capabilities that make it possible to create new value by matching our technologies to the issues faced by customers is one of ROHM’s major strengths.
In the future, it will be necessary to meet conflicting needs, such as balancing miniaturization and greater performance with greater energy savings and power. In order to meet these needs of society, I want to propose solutions encompassing next-generation power devices, including SiC. Then, we will develop products with high value added by leveraging ROHM’s integral technologies, and thus contribute to solutions to the problems faced by global society.
Taking on the Challenge of Proposing Solutions that Meet Customers’ Needs by Leveraging Power and Analog Technology
I am in charge of the development of shunt resistors, which are primarily used to detect current in a wide range of fields, including automobiles and industrial equipment. The products I work on boast the highest specs in the industry, but we are working to develop technologies to further improve performance and expand our product lineup.
Meeting the needs of a broad range of customers is one of ROHM’s strengths as our resistors incorporate both analog technology, which is based on a wide lineup of highly reliable thick membrane resistors that can be used for general purposes, and power technology, whose foundation is shunt resistors for high voltages. As price competition grows fiercer due to the rise of Asian manufacturers in China, Taiwan, and Korea, ROHM is focusing on products with the highest specs in the industry and trying to become the industry leader by proposing solutions that leverage both power and analog technology.
Established as a resistor manufacturer, ROHM has expanded its business into ICs, power devices, and other products based on its resistor technology. I hope to continue to contribute to further growth through high-value-added products that combine these technologies. At a time when there is the need for detailed proposals that take into considerationcustomer circuit designs and other factors, it is important to make application-level proposals, including modules, not proposals for individual products. To achieve that, I want to also take on the challenge of developing new modules that combine shunt resistors and other devices.

Power and Analog Technologies: ROHM’s Focus Areas
- Power
- SiC devices can achieve significantly lower loss and miniaturization versus conventional silicon (Si) semiconductors. Amid ever-growing needs for energy savings, ROHM has been a global pioneer in the development and enhancement of its SiC product lineup, which has been broadly adopted in a range of applications, especially in the automotive and industrial equipment-related markets. We will continue to propose optimal power solutions to our customers by integrating our element development and module technologies, not only for SiC devices, but also conventional Si devices and other electronic components.
- Analog
- Analog technologies are elemental technologies processing information that is in constant flux into electrical signals. These are widely applied to power supply control circuits that support the stable operation of electronic equipment, motors, and more. Electronic equipment demand will continue its dramatic growth, including in the use of data through IoT and artificial intelligence (AI) and the expansion of autonomous driving. The analog semiconductors used in this equipment are expected to achieve even higher performance, energy savings, and miniaturization. ROHM is able to meet customer needs through its engineers’ in-depth familiarity of analog technologies and optimal designs, and its advanced elemental and integral technologies cultivated over many years.
