Implications, context, and why it matters.

China’s mature-node capacity surge masks overcapacity and price erosion risks

• China is pushing mature nodes (28-nanometer and above, the older, lower-cost manufacturing processes) with its share of global capacity rising from 29% in 2023 to 33% by 2027 1. As of early 2024 it ran 44 wafer fabs (semiconductor factories), with a pipeline of 32 more sites 2.
• SMIC cut 28nm wafer quotes from $2,500 to $1,500 in 2024 as oversupply hit 3. ASML (Dutch lithography toolmaker) imports rose 1050% in 2023 2 with subsidies above $150 billion over the past decade 4.
• Global mature to advanced process ratios stay near 7:3 through 2027 1. New Chinese lines meet established peers in low margin, price sensitive segments. Advanced nodes use smaller transistors for higher performance, while mature nodes serve cost driven uses.

Specialty consumable suppliers for 28nm-and-above fabs have an opening

• China will add 240,000 wafers per month of 300mm (300-millimeter wafer) capacity after 2026 3, which lifts demand for silicon wafers and specialty gases. Fabs also need chemical mechanical planarization slurries (materials used to polish wafers), mass flow controllers (devices that precisely regulate gas flow in tools), and abatement systems (equipment that treats hazardous exhaust gases) that sit outside export controls focused on advanced nodes 4.
• EV (electric vehicle) penetration tops 50% of new passenger cars in China 3, and domestic auto original equipment manufacturers (OEMs) co design chips with foundries (contract chip manufacturers) to lock priority capacity 3. Vendors can pitch long term supply deals to SMIC in Beijing and Shanghai Lingang, Hua Hong in Wuxi phase two, and Nexchip’s new lines 5.
• Pick which of the 23 fabs under construction will ramp first (begin high-volume production) 2, then secure relationships before domestic Chinese substitutes mature, especially for high purity chemicals and advanced consumables.
