Our Business

Top-class substrates for global market.

We develop and manufacture metal-ceramic substrates that are indispensable for power electronics which convert and control high voltage and high current. We have achieved a major share of the global market in metallic aluminum nitride ceramic substrates, making us one of the leading companies in this field. With over 30 years of experience in manufacturing metal-ceramic substrates, our goal is to further expand our global market share by leveraging our advanced research and development capabilities to deliver high-quality products to our customers.

Metal ceramic substrates used worldwide, especially in clean energy applications.

Our metal-ceramic substrates are used in products essential to both social infrastructure and daily life, including customers’ production lines and various public systems. In recent years, demand for our products has grown significantly in clean energy applications, such as electric vehicles and solar and wind power generation, driven by the global shift toward a decarbonized society. Overseas demand is also steadily increasing.

Contributing to the creation of a sustainable society through our business.

As the world moves toward energy conservation and a decarbonized society, we face the challenge of creating a future in which coming generations can live prosperous lives while protecting the global environment. Energy conservation measures are needed across various aspects of daily life, for example, improving train fuel efficiency, promoting the adoption of electric vehicles, and reducing power consumption in home appliances and other products. Solar and wind power generation, which do not rely on fossil fuels, will also become increasingly prevalent.

The metal-ceramic substrates we manufacture are used not only in power modules that convert energy in eco-friendly vehicles such as electric cars, but also in power modules that stabilize the intermittent energy generated from renewable sources like solar and wind. In this way, our products support broader energy-conservation efforts. Through the development and manufacture of metal-ceramic substrates, indispensable components in power modules for clean energy applications, we aim to contribute to the creation of a sustainable society.
