Hua Hong Semiconductor

What Hua Hong Semiconductor does

Hua Hong Semiconductor (HHGrace) is China's second-largest pure-play semiconductor foundry and the sixth-largest globally, operating an "8-inch + 12-inch" specialty process strategy focused on embedded and standalone non-volatile memory (eFlash, OTP, MTP), power discrete (Super Junction MOSFET, IGBT), analog & power management (BCD at 0.18µm and 90nm), and logic & RF technologies. The company serves global semiconductor design houses and integrated device manufacturers requiring automotive-grade, industrial, consumer electronics, communications, new energy, and IoT chips, with named customers including Huawei (7nm AI chip collaboration via Huali Microelectronics), Biren (GPU tape-out), and STMicroelectronics (STM32 microcontroller manufacturing). Hua Hong operates five major fabrication facilities — three 8-inch fabs in Shanghai (Jinqiao and Zhangjiang) and two 12-inch fabs in Wuxi — with combined 12-inch monthly capacity exceeding 177,500 wafers, and is acquiring Shanghai Huali Microelectronics (~97.5% stake, RMB 8.27 billion / ~US$1.2 billion, approved June 2026) to add approximately 38,000 wafers/month and 7nm chipmaking capability, making it the second Chinese foundry (after SMIC) capable of advanced 7nm production.

Hua Hong generates revenue primarily through toll wafer fabrication services — one-time manufacturing fees per wafer shipped — complemented by value-added services including design support, multi-project wafer (MPW) shuttles, mask making, and backend packaging and testing under a one-stop model. The company runs a direct enterprise field-sales model with no distributors or resellers, supported by regional sales offices in Taiwan (Zhubei/Hsinchu), Japan (Tokyo), the United States (Milpitas, CA), and Europe. Customer relationships are technical and long-cycle, structured around process qualification, design-in, and volume ramp across multiple wafer sizes and nodes. Hua Hong is dual-listed on the Hong Kong Stock Exchange (01347.HK, since 2014) and the Shanghai STAR Market (688347.SH, since 2023), and is a member of the state-affiliated Hua Hong Group (华虹集团) industrial conglomerate. Reported revenue was approximately $2.4 billion in 2025, up from $2.0 billion in 2024, with record quarterly sales during the year driven by specialty process demand and the China AI infrastructure buildout.

Direct peers

• Tower Semiconductor: Tower Semiconductor is a specialty foundry focused on RF, analog, power, and MEMS. Closely comparable to Hua Hong's specialty foundry strategy in process technology and customer base.
• SMIC: Semiconductor Manufacturing International Corporation is China's largest pure-play foundry and the only other Chinese chipmaker with 7nm capability. Hua Hong is now positioned as China's #2 pure-play foundry post-Huali acquisition.
• GlobalFoundries: GlobalFoundries is the closest international analog as a specialty-focused foundry serving automotive, industrial, and RF. Hua Hong competes head-to-head in many of the same specialty process platforms and end markets.
• UMC: United Microelectronics Corporation is a Taiwan-based pure-play foundry with significant mature-node and specialty exposure. Competes with Hua Hong in 8-inch and 12-inch specialty processes including eFlash and power.
• Vanguard International Semiconductor: VIS is a Taiwan-based specialty foundry focused on 8-inch mature nodes serving power management, display drivers, and analog. Highly comparable to Hua Hong's 8-inch specialty positioning in Shanghai.
• Powerchip Semiconductor Manufacturing: PSMC is a Taiwan-based foundry with significant DRAM and specialty foundry operations. Competes with Hua Hong in mature and specialty nodes, including power discrete.

Broad incumbents

• TSMC: Taiwan Semiconductor Manufacturing Company is the global foundry leader. Hua Hong explicitly avoids competing at TSMC's leading-edge logic nodes and instead targets specialty and trailing-edge nodes where TSMC does not aggressively compete.
• Samsung Foundry: Samsung's foundry division competes broadly across logic nodes including 7nm and below. Hua Hong's Huali Microelectronics subsidiary directly competes with Samsung for advanced AI chip production from Huawei.
• Intel Foundry Services: Intel Foundry offers advanced-node foundry services as part of Intel's broader IDM business. Operates in adjacent advanced-node capacity to Hua Hong's emerging 7nm capability.

Others

• ASML Holding: ASML is the dominant supplier of advanced lithography (EUV/DUV) systems. Not a foundry peer, but directly material to Hua Hong's ability to scale 7nm and below given current U.S./Dutch export restrictions on advanced tools.
