SILAN
SILAN – Leading IDM Semiconductor Product Supplier in China
SILAN‘s core strengths lie in its true full‑chain IDM capabilities, solid production capacity deployment, and long‑term research and development investment.
In full‑chain IDM capabilities, SILAN is one of the few domestic IDM leaders to achieve a complete closed loop from design and wafer manufacturing to packaging, testing, and application verification. From the early process refinement of 5‑ and 6‑inch production lines, to the full‑capacity profitability of 8‑ and 12‑inch power lines, and the successive establishment of 12‑inch high‑end analog circuit chip lines and 8‑inch SiC power chip lines, SILAN has built all core production capacity independently — avoiding acquisition shortcuts and capital arbitrage. This asset‑heavy model delivers an industrial security foundation free from foundry constraints, external capacity bottlenecks, and technology supply cut‑offs.
In power semiconductors, SILAN ranks fifth among global power semiconductor companies. Its product line covers power semiconductor products represented by IGBTs, super‑junction MOSFETs, and high‑density trench‑gate MOSFETs, as well as third‑generation compound power semiconductors (SiC and GaN power devices), intelligent power modules (IPM), and automotive‑grade and industrial‑grade power modules (PIM). In 2025, SILAN’s IPM intelligent power modules were used by mainstream white goods manufacturers in China in volumes exceeding 250 million units, with application scenarios extending from white goods to industrial and automotive fields. The automotive‑grade B7 power module, based on self‑developed FSV++ IGBT chip technology, topped the "2026 Top 10 Domestic Automotive‑Grade Chip New Products" list.
In silicon carbide (SiC) and third‑generation semiconductors, SILAN has completed a full industrial layout from 6 inches to 8 inches. The Silan Mingjia 6‑inch SiC power device chip line has achieved stable mass production with near‑full capacity utilization; the Xiamen 8‑inch SiC line, with a total investment of RMB 7 billion, successfully came online in Q4 2025 with a monthly capacity of 5,000 wafers, expected to ramp up production in the second half of 2026. Second‑ and fourth‑generation SiC‑MOS devices have been delivered in large volumes, and the electric vehicle main motor drive module produced with self‑developed second‑generation SiC‑MOSFET chips has accumulated shipments exceeding 100,000 units. SILAN achieves full‑chain SiC autonomy: device design, chip process, tape‑out manufacturing, and packaging and testing verification are all self‑developed and self‑owned, with no external technology dependence.
In high‑end analog chips and AI computing power supplies, SILAN is opening a third growth curve. The 12‑inch high‑end analog IC line in Xiamen, with a planned total investment of RMB 20 billion (RMB 10 billion for Phase I), has officially broken ground, targeting high‑value markets including AI server power supplies, new energy vehicles, and robotics. The company has launched four key analog chips for AI computing power supplies and has built a complete AI server power supply system solution covering SiC, DPMOS, LVMOS, GaN, DrMOS, eFuse, Multiphase Controller, POL, and other products, fully covering applications including SST, HVDC, PSU, IBC, Hotswap, BBU, and VRM.
In R&D investment and talent accumulation, SILAN‘s R&D expenditure grew from RMB 628 million in 2021 to RMB 1.172 billion in 2025, with R&D investment consistently accounting for approximately 9% of revenue. The company employs over 800 IC design R&D personnel, and its chip process, packaging technology, testing technology R&D, and product application support teams exceed 3,600 people, including over 800 PhD and master’s degree holders. SILAN has been repeatedly recognized as one of "China‘s Top Ten IC Design Enterprises," "China’s Top Ten Semiconductor Power Device Enterprises," "China‘s Top Ten Semiconductor MEMS Enterprises," and "China’s Top Ten SiC IDM Enterprises".
