Taiwan foundries see strong 2Q26 rebound, led by TSMC's 3nm ramp and packaging, with peers eyeing HBM and interposer.
Intel 18A yield beats plan, 14A wins Tesla. Niche logic with EMIB/Foveros and PowerVia could reshape foundry race.
Mature foundries shift structurally as capacity cuts and AI demand lift utilization and pricing, while Tier 2 players gain order wins.
AI demand reshapes chip supply; advanced nodes and packaging turn scarce, with early lockdowns now defining leadership.
Foundry shifts: Samsung Taylor starts, SMIC expands, HuaHong refines, Nexchip and CXMT ally, mature node prices rise.
Taiwanese foundries face structural shifts: TSMC consolidates 12" mature nodes, UMC hikes 8" prices, VIS pivots to PMICs, and PSMC moves to high-value processes amid supply-demand restructuring.
Backed by massive subsidies, China's equipment makers have made gains in mature nodes and initial inroads into advanced processes, but ecosystem gaps and geopolitics cap long-term growth.
The Diamond reports cover major foundries such as TSMC, UMC, Samsung, SMIC, and GlobalFoundries, etc. The Diamond reports provide extended analyses of these foundries' production capacity figures, process node migration and capacity utilization rates. Furthermore, the Diamond reports discuss the competition among foundries and among major regional markets, including Mainland China, Taiwan, South Korea, Japan, etc. The dynamics of competition and cooperation, together with capacity utilization rates of specific nodes, wafer prices, wafer input from major clients at advanced nodes, etc., are all especially highlighted in the Diamond reports
Samsung accelerates the reduction of mature capacities while hiking prices on fully-loaded advanced nodes. Meanwhile, benefiting from supply shifts and early stocking against rising component costs, Chinese foundries maintain high utilization in mature nodes, triggering price hikes for tight capacities. Simultaneously, driven by the localization trend, major Chinese players are actively expanding new fabs.
Driven by strong demand, TSMC accelerates global expansions for advanced nodes and packaging; UMC pushes joint-node sampling despite delays and develops silicon photonics; Vanguard comprehensively raises prices and evaluates overseas expansion; PSMC optimizes profits via memory partnerships, line consolidation, and price hikes.
