AMEC’s six-tool release illustrates a push from a narrow etch specialist toward a broader process-equipment platform: ultra-high-aspect-ratio etching for advanced 3D memory, PECVD and ALD/metal-deposition systems for complex film stacks and word lines, and high-temperature CVD epitaxy for silicon-carbide power devices. 8

Its 70:1–90:1 aspect-ratio etcher targets the difficult deep features required as 3D NAND and DRAM add layers; its PECVD and ALD molybdenum tools address high-throughput dielectric-stack deposition and conformal metal fill; and its SiC HTCVD tool addresses the transition to larger-diameter power-semiconductor wafers. These are strategically important, high-value process steps rather than peripheral equipment. 8

AMEC’s reported installed base—more than 8,800 production reaction chambers, 170-plus customers, and 220-plus chip and LED lines across five regions—suggests that at least some domestic process tools have passed the more meaningful test of repeated customer deployment, not merely laboratory demonstration. The figures are company-reported and should not by themselves be read as proof of leading-edge-node equivalence. 8

NAURA’s broad portfolios in etch, deposition, cleaning and thermal processing likewise indicate that Chinese firms can now supply multiple tool categories to fabs, improving resilience against tighter export controls and enabling more domestic process integration. However, broad product coverage is not the same as demonstrated parity at the most demanding logic nodes. 4

Shanghai Micro Electronics Equipment’s KrF dry and I-line lithography systems, reportedly used to process more than 10 million cumulative customer wafers, demonstrate practical production use in mature and selected specialty processes. They do not establish domestic capability in state-of-the-art EUV or the full advanced-logic lithography stack. 4

Ion implantation requires exceptionally stable, precisely controlled ion beams across different current and energy ranges, while also controlling dose, uniformity, contamination, wafer charging, throughput and implant damage. High-current and high-energy systems have distinctly tougher beam-transport, acceleration and process-control requirements than medium-current systems. 236

The reported domestic landscape is therefore still early-stage: NAURA has displayed plasma-immersion and medium-current systems; Jingsheng is pursuing a silicon medium-current implanter through customer validation; and AEn Ion has presented a broader range spanning medium-current, high-current, high-energy and specialty tools. The critical distinction is between exhibiting a product, completing validation, and achieving sustained high-yield volume use. 4

Reported localization is below 15% overall for ion implanters, below 10% for high-current/high-beam systems, and effectively near zero for high-energy models. Advanced foreign systems—and reportedly even suitable used tools—are unavailable under export restrictions, leaving fabs dependent on older imported equipment and potentially reducing yield and operating stability. These figures and the used-equipment claim require caution because the available evidence is industry reporting rather than official trade or customs data. 4

Most domestic implanter makers reportedly remain unprofitable because the category demands sustained, expensive R&D, long customer qualification cycles and a small initial installed base. That combination makes this a “deep-water” localization problem: capital alone cannot quickly replace accumulated process knowledge and field reliability. 4

Inspection and metrology do not directly pattern, etch or deposit material, but they determine whether a wafer is acceptable or scrap and provide the feedback needed to control a nanometer-scale process. Without trusted defect detection, overlay measurement, critical-dimension metrology and process-control data, fabs cannot confidently use a new process tool at advanced nodes. 4

China’s historical localization in front-end inspection and measurement was reportedly below 10%, and independent analysis likewise identifies wafer inspection, advanced ion implantation and advanced-logic testing among categories where Chinese capacity remains limited. 4

This makes fab trust the decisive next hurdle. Chinese vendors increasingly benchmarking foreign systems is meaningful because it shifts the standard from “a domestic alternative exists” to demonstrated comparability in uptime, repeatability, defect sensitivity, process window, yield impact and service support. Achieving that trust is essential for nanometer-era logic and AI-oriented memory, where a marginal process-control failure can erase the value of progress in etch or deposition. 4
