Rooted in Japan, branched in Europe: Growing solutions together

Since its foundation, the ROHM Group has already committed itself to support society's development and enriching people’s lives. Rooted in Japan, the company has grown into a globally operating corporate group with production facilities, design centers and sales offices in many countries of the world. In the middle of Europe lies the EMEA branch with Headquarters near Düsseldorf, as well as offices in France, England, Spain, Italy, and the Software Design Center in Finland. The idea behind this branched structure is to think globally and act locally. This way ROHM aims to provide customers all over Europe with expert contact persons who can grasp complex issues in the respective language and contribute to the solutions of design challenges.

Isao Matsumoto, President ROHM Co., Ltd.

“Our goal is to provide electronic solutions for the future and support our customers as a competent partner and consultant. Next to technical support, for example, via our European power lab, personal exchange with our partners and careful listening regarding our industry’s and customers’ needs is key to creating tailor-made solutions in the long run.”

Quality standards


"Quality First" is the foundation of everything that ROHM practices. Quality is not limited to the performance of finished products but includes cost, delivery, service and environment as well. We at ROHM believe that quality represents the customer's level of satisfaction in all these areas.

Dirk Peters QA EU

“The Quality Assurance Center (QAC), which is included at ROHM's European Headquarters in Willich, was founded more than 20 years ago to ensure the local support structure based on customer needs. ROHM’s local support is an extension of the corporate quality strategy to offer a high level of customer service. With state-of-the-art investigation equipment, problems can be assessed and analyzed quickly to ensure a fast response. Zero Defect mindset, starting from development until mass production is more important than ever for the future success for semiconductor companies. When it comes to defects, comprehensive cooperation between all parties is required. The focus of this cooperation is to understand defect causes regardless of who is responsible. Development of new working structures, closing of information gaps, reconsideration of the 8D flow and teamwork will be essential to get closer to the Zero failure target."
