Memory Capacity Expansion Plus Overseas Equipment Delivery Disruptions: Domestic Semiconductor Equipment Faces Dual Growth Drivers
nashnova research
A global memory-chip expansion cycle and delivery bottlenecks at major overseas equipment makers are opening both domestic substitution and export opportunities for Chinese semiconductor equipment firms; Guojin Securities mapped out the key segments in a July 9 report.
Why is memory suddenly in short supply?
A single AI server uses 8–10× the DRAM and 3× the NAND flash of a conventional server. This means → high-end memory demand is not growing steadily — AI compute needs yanked it up in one move.
Samsung and SK Hynix have tilted 80–90% of advanced capacity toward HBM — high-bandwidth memory that feeds data to AI chips. Micron shifted roughly 70% to HBM and high-end DDR5. In plain terms = the majors are all-in on premium products, squeezing generic memory supply.
The three leading fabs hold only about 4 weeks of inventory, well below the healthy 8–12 week range — the supply gap is already showing up in prices.
How extreme is the price spike?
TrendForce projects DDR5 contract prices up 58–63% quarter-on-quarter in Q2 2026, with NAND flash contracts up 70–75% — a single-quarter jump rarely seen in the past decade.
Improved profits are driving capex: Micron's 2026 budget rises to $27 billion, up 70.3% year-on-year; SK Hynix's 2025 capex is up 75.5%.
Samsung, SK Hynix, and Micron together plan roughly $53.5 billion in 2026 capex, 16% above 2025. This means → large equipment purchase orders are on the way.
Why can't the overseas equipment makers deliver?
Applied Materials, Tokyo Electron, and peers face shortages of critical components and saturated capacity; lead times for front-end and memory equipment have stretched to 12–24 months, with price hikes on top.
This means → Samsung, SK Hynix, and Micron are forced to diversify suppliers — not out of preference for Chinese equipment, but because they cannot afford to wait.
Chinese etch, thin-film, cleaning, and test equipment makers — offering faster delivery and lower cost — are seeing accelerated qualification and order placement in South Korea and Southeast Asia, building a second growth curve.
Do the order numbers back this up?
AMEC's (中微公司) contract liabilities — a proxy for signed-but-undelivered orders — rose from ¥590 million in 2020 to ¥3.04 billion in 2025. Piotech's (拓荆科技) jumped from ¥130 million to ¥4.85 billion over the same period.
Chinese semiconductor equipment firms spent a combined ¥18.58 billion on R&D in 2025, more than 5× the 2020 figure. This reflects an industry betting real money on technology breakthroughs.
Domestically, CXMT (长鑫科技) and YMTC (长江存储) plan combined equipment procurement of ¥55–63 billion in 2026 — a localization-driven purchasing policy that directly benefits homegrown suppliers.
Which sub-segments have the most room for substitution?
Metrology & inspection equipment — quality-control tools used across the entire wafer-fab process — accounts for roughly 13% of global equipment market value, yet China's localization rate is only 1–10%, barely above lithography's 0–1%. The global market is projected to grow from about $19.2 billion in 2025 to over $32.1 billion by 2030.
Final test (FT) equipment — the machines that run function tests on packaged chips: Advantest and Teradyne held a combined 99% market share in 2023. With AI chips and HBM driving higher channel counts and speeds, high-end FT testers now price above ¥11 million per unit.
In plain terms = these two segments sit at the intersection of "lowest localization rate, steepest price increases, and most urgent customer need" — maximum substitution upside.
Where are the risks?
The report flags three: global wafer-fab capex falling short of expectations, R&D and qualification timelines slipping for high-end equipment, and geopolitical trade and supply-chain instability.
Metrology and high-speed memory test equipment have high technical barriers; even after R&D is done, products require extended fab-level qualification before revenue is recognized. Whether revenue timing can keep pace with market expectations is the key checkpoint.
This means → the direction of the opportunity is clear, but the qualification cycle from order to profit is not short — timing matters more than thesis.
