DB HiTek's Breakthrough in Semiconductor Technology

DB HiTek, a South Korean leader in the semiconductor foundry industry, has recently achieved a significant milestone by completing the reliability qualification for its 1,200 V silicon carbide (SiC) metal-oxide-semiconductor field-effect transistor (MOSFET) process. This accomplishment is particularly noteworthy as it positions DB HiTek on the cutting edge of the global semiconductor market, especially in the domain of 8-inch wafers.

The company announced this achievement on September 9, 2026, and is now gearing up for volume production, targeting a launch in 2027. This development comes amid a broader industry shift where 8-inch wafers, previously dominated by 6-inch formats, are now becoming the standard for improved production efficiency and cost-effectiveness. Recognizing this trend, DB HiTek has taken the initiative by advancing its 8-inch SiC processing technology, thereby consolidating its role in the foundry service industry.

The Relevance of Silicon Carbide Technology

Silicon carbide is emerging as a preferred material in the production of semiconductors due to its superior performance characteristics, particularly under high-voltage and high-temperature conditions. Such features make SiC devices particularly suitable for electric vehicles (EVs), renewable energy systems, and high-performance industrial power equipment.

DB HiTek's success in the reliability qualification signifies not just a technological achievement, but it also highlights the company’s commitment to enhancing the capabilities of its foundry services. The foundation established through this qualification allows them to support a range of applications that leverage high-power SiC MOSFETs effectively.

Unveiling New Process Development Kits

As part of their commercial strategy, DB HiTek will be providing customers with Process Design Kits (PDKs) tailored for their first and second generation of 1,200 V SiC MOSFETs. The company is also set to release a third-generation PDK in November, which promises to streamline product development further. Notably, these kits are designed to reduce the resources needed in the initial stages of development and accelerate prototype fabrication, ultimately shortening product development timelines by over a year.

For instance, the specifications of the second-generation process, outlined in the PDK, achieve a specific on-resistance of 2.5 mΩ•cm² or lower, along with a threshold voltage exceeding 3 V at an on-state gate voltage of 18 V. These enhancements will help DB HiTek to meet the demands of its clients while maintaining a competitive edge in the market.

Future Preparations and Strategic Goals

Looking forward, DB HiTek plans to finalize the production process and make its services accessible to long-time partners by the third quarter of 2026. Furthermore, a full rollout to all prospective customers is envisioned for the second quarter of 2027. This strategic trajectory is indicative of DB HiTek’s ambition to become a key player in the next-generation power semiconductor sector.
