IGBTs
The development of high-performance IGBTs is one of our core competencies. Regardless of your specific requirements, we support the development of innovative and highly competitive IGBT technologies tailored to your target applications and available process capabilities.
We bring extensive experience in the development of IGBTs ranging from 600V to 6.5kV for applications spanning automotive systems, industrial drives, traction, and high-voltage energy transmission. Our approach combines device physics, process integration, reliability engineering, and application knowledge to achieve optimal device performance.
Whether the goal is to develop a next-generation platform, improve an existing technology, increase manufacturing yield or address new market requirements, we provide practical and cost efficient solutions.
A key differentiator of our work is the ability to optimize the complete system — from silicon design and process technology to module integration and application behavior. This approach enables performance improvements that go far beyond the limits of conventional IGBT trade-off curve optimization.
