AMEC
R&D, manufacturing, and sales of high-end semiconductor plasma etching equipment and MOCVD equipment
Achieved domestic technological breakthroughs in plasma etching and MOCVD, with product performance reaching internationally advanced levels, deeply bound to the world's major wafer fabs
Company Overview
Advanced Micro-Fabrication Equipment Inc. China (AMEC) was founded in 2004 and listed on the STAR Market of the Shanghai Stock Exchange in 2019 (stock code: 688012). Headquartered in Shanghai, the company is a globally leading manufacturer of high-end semiconductor equipment. Its main business focuses on plasma etching equipment (CCP, ICP) and MOCVD equipment, while also expanding into thin-film deposition, inspection, and other extended equipment. In the AI industry chain, AMEC is positioned in the semiconductor manufacturing and materials segment, providing core process equipment for chip manufacturing and serving as a key force in the domestic substitution of semiconductor equipment.
Plasma etching equipment: Covers two major technical routes, CCP (capacitively coupled plasma) and ICP (inductively coupled plasma), and is used for key etching processes such as dielectric layers and through-silicon vias (TSV) in logic and memory chips. The products cover 5nm and more advanced process nodes and have entered leading fabs including TSMC, YMTC, and SMIC. In 2023, this business generated revenue of approximately RMB 4.46 billion, up over 35% year-on-year.
MOCVD equipment: Used for epitaxial growth of compound semiconductors for LEDs, power devices, and laser diodes. AMEC's MOCVD equipment holds a leading market share in the Mini/Micro LED field, with cumulative global shipments exceeding 1,000 units. In 2023, revenue was approximately RMB 1.25 billion, with a slight decline affected by the LED industry cycle.
Spare parts and services: Provides value-added services such as equipment maintenance, spare parts replacement, and process optimization, with high gross margins and strong customer stickiness. In 2023, revenue was approximately RMB 620 million.
| Product Line | Revenue Share | Core Customers | Gross Margin |
|---|---|---|---|
| Plasma etching equipment | ~70% | TSMC, SMIC, YMTC | ~52% |
| MOCVD equipment | ~20% | San'an Optoelectronics, Huacan Optoelectronics | ~45% |
| Spare parts and services | ~10% | All equipment customers | ~55% |
Technical Moat
Moat 1: High Aspect Ratio Plasma Etching Technology
The company's self-developed CCP etching equipment can achieve uniform, damage-free etching at extremely high aspect ratios (exceeding 60:1), meeting the stringent requirements of 3D NAND flash memory with 128+ layers and advanced logic chips. This technology is mastered by only a handful of manufacturers globally, and AMEC is the only company in China to achieve mass production breakthroughs.
Moat 2: Self-Reliant Control of Core Components
The company's core components, such as RF power supplies, vacuum chambers, and gas distribution systems, are gradually achieving domestic substitution, reducing dependence on overseas supply chains. Meanwhile, the company holds extensive patents in airflow field and temperature field control for MOCVD equipment, forming technical barriers.

| Downstream Customers | TSMC, SMIC, YMTC, Hua Hong Semiconductor, Sanan Optoelectronics |
Financials and Growth
| Metric | Data |
|---|---|
| Revenue (2023) | RMB 6.264 billion, up 32% YoY |
| Net Profit Attributable to Parent Company | RMB 1.786 billion, up 52% YoY |
| Gross Margin | 50.73% |
| Net Margin | 28.5% |
| R&D Expense Ratio | ~12% |
| Core Growth Drivers | 1) Accelerated expansion of domestic wafer fabs, with rising penetration of domestic equipment; 2) Increased etching demand for advanced process nodes; 3) Product line extending into thin film deposition and inspection equipment, opening up new growth space |
Main Risks:
- Technology Iteration Risk: Overseas industry leaders maintain their lead in advanced process nodes. If the company's products fail to keep pace with process technologies at 3nm and below, it may lose growth momentum.
- Geopolitical Risk: The U.S. Entity List restricts customers such as SMIC, which may indirectly affect the company's equipment shipments; certain core imported components still face supply disruption risks.
- Customer Concentration Risk: The top five customers account for over 50% of total revenue, and order fluctuations from a single customer could significantly impact performance.
- Industry Cyclicality Risk: The semiconductor industry exhibits pronounced prosperity cycles, and a slowdown in capacity expansion will suppress equipment demand.
Core Investment Thesis / Industry Value Summary:
AMEC is a benchmark enterprise for domestic substitution of semiconductor equipment in China. Leveraging its leading plasma etching technology and MOCVD products, the company fully benefits from the AI-driven chip manufacturing capacity expansion cycle. In the long term, the company is expected to expand from etching equipment to a broader process platform, achieving a transformation into a "platform-type" equipment manufacturer with significant investment value.
