What Sanan Semiconductor does
Sanan Semiconductor is a wholly-owned subsidiary of listed Chinese optoelectronics group Sanan Optoelectronics (SH600703), focused on wide-bandgap (WBG) compound semiconductors — principally Silicon Carbide (SiC) and Gallium Nitride (GaN). Founded in 2020 and headquartered in Changsha, the company operates one of the few fully vertically integrated SiC device platforms in the world, controlling every step from crystal growth through substrate fabrication, epitaxy, chip processing, packaging, and final test. This integration is intended to give it control over yield, cost, and roadmap timing in a market where substrate supply has historically been the dominant bottleneck.
Its product portfolio targets power-semiconductor applications in automotive/EV (traction inverters, on-board chargers, DC-DC converters), renewable energy (solar inverters, energy-storage power conversion), industrial and data center power (server PSUs, UPS), consumer appliances (white-goods motor drives), and communications infrastructure. The company claims cumulative shipments exceeding 300 million SiC chips/devices to a base of more than 800 customers globally, with an R&D organization of more than 700 staff and a patent estate of more than 400 filings. Current installed capacity targets 360,000 6-inch and 480,000 8-inch wafers per year once Phase I and II are fully operational, with a stated long-term ambition of 1 million wafers per year.
The business model is direct B2B sale of WBG discrete devices and modules to industrial OEM and tier-1 customers; pricing is not publicly disclosed and there is no consumer-facing channel. Sanan monetizes through wafer and chip unit volumes, qualification of automotive-grade SKUs (AEC-Q101), and increasingly through a $3.2 billion 8-inch SiC joint venture with STMicroelectronics in Chongqing (51% Sanan / 49% ST), which provides a tier-1 customer anchor and shared capex. Strategic partnerships such as the 2024 Vertiv agreement for data center power conversion and an academic collaboration with FAU Erlangen-Nürnberg point to a deliberate broadening of verticals and talent pipelines. The combined capital committed to the Changsha base ($2.3B on 667,000 sqm) and the STMicro JV underwrites an aggressive capacity expansion that runs ahead of current revenue of $131.6M in 2023.
