China’s Power Chip Breakthrough: Gallium Oxide Device Hits 1‑Ampere, 900‑Volt Milestone

Shanghai’s Jiachi Power Technology has announced a landmark achievement in the race for next‑generation power semiconductors. Using gallium oxide—a material prized for its ultra‑high voltage tolerance and low energy loss—the company completed the first‑phase tape‑out of a vertical MOSFET chip that can carry more than one ampere of current while withstanding over 900 volts. This performance shatters previous world records and clears a major hurdle that has held gallium‑oxide devices back: reliable, high‑current operation. The breakthrough stems from two home‑grown innovations. First, engineers designed a new cell architecture and terminal layout that evenly spreads the electric field, boosting stability and breakdown voltage. Second, they perfected a self‑aligned ion‑implantation process that precisely dopes the vertical channel, eliminating the leakage and inconsistency that plagued earlier prototypes. Test results show a threshold voltage of 3.9 V, an on‑resistance of 33 mΩ·cm², and leakage under 3 µA—numbers comparable to mature silicon‑carbide technologies. Gallium oxide’s ability to handle high voltages with minimal loss makes it ideal for renewable‑energy converters, smart‑grid equipment, and advanced industrial power supplies. Jiachi Power says the next steps will focus on scaling production, improving reliability, and delivering commercial‑grade chips that could help China lead the fourth‑generation semiconductor market.

Nuclear Tech: Powering Medicine, Agriculture, and Everyday Life

Since the start of 2026 China’s nuclear‑medicine market has taken off, with new isotopes and imaging tools rolling out across Tianjin, Sichuan and other regions. The surge is driven by a steady flow of funding and the backing of big energy groups such as CNNC, CGN and SPIC, which are expanding their reach beyond power plants into the production of medical isotopes like carbon‑13 and technetium‑99m. But the impact of nuclear technology goes far beyond hospitals. At the 2026 China International Fair for Trade in Services, exhibitors showed how radiation and isotope tools are reshaping key sectors: they spot flaws in oil‑and‑gas pipelines, help recycle batteries, clean wastewater from solar‑panel factories, and even keep potatoes from sprouting during storage. In agriculture, radiation‑induced breeding is creating hardier crops, while in industry, non‑destructive testing ensures the safety of bridges, aircraft and machinery. Everyday life feels the ripple too—airport security scanners, hospital CT scans, and food‑sterilization equipment all rely on the same nuclear principles. Recognizing this, China enacted the Atomic Energy Law in January 2026, officially encouraging the use of isotopes and radiation devices in industry, agriculture, health and environmental protection. The result is a rapidly growing nuclear‑technology market that now contributes a noticeable slice of national GDP, mirroring trends in the United States, Europe and Japan.
