Semiconductors & Chips

China's semiconductor self-sufficiency campaign is no longer a design-and-memory story alone; it is now visibly broadening into foundry and equipment, as AI demand and export controls push every link of the chain to move at once. Xiaomi's Xuanjie O3 with CXMT LPDDR6 remains the flagship marker of design-track integration, but second-quarter results from SMIC and Hua Hong and a new equipment base from Tuojing Technology show the fabrication track posting hard numbers. The ceiling remains the same — advanced logic lithography is still foreign — yet the gap below it is closing faster than the design-track success alone implied.

The Xiaomi Xuanjie event on August 24 put three in-house chips into production: the O3 SoC (133 mm², 24B transistors, AnTuTu 5,228,014) ships in September with the Xiaomi 18 Fold and Pad 9 Pro Max; the O100 AI accelerator (6nm, 3D wafer-level stacking, 1.22 TB/s, 330 tokens/s on MiMo 3B) and the D100 AD chip are validated for commercial launch next year ¹. The decisive detail is that CXMT is the core LPDDR6 partner for the O3, making it the world's first flagship SoC with LPDDR6 and the first domestic LPDDR6 in a flagship processor ². That closes a memory dependency on the design track — though the logic die itself is still likely TSMC 3nm, keeping the foundry link external.

The foundry side now has hard evidence of momentum. SMIC's Q2 2026 sales broke $3 billion (up 36.1% YoY, 20% QoQ), with gross margin at 25.3% and net profit up 261.7% YoY; Hua Hong set a revenue record of $717.5 million, with utilization at 102.8% and profit up 386% ³. Both guided Q3 higher. Nearly all of this is China-region business (SMIC 90.2%, Hua Hong 78.6%) and consumer/communications, i.e., mature-node AI spillover, not leading-edge logic. The numbers show the AI buildout is filling domestic fabs, but they also underline that the strategic ceiling — 7nm and below — still depends on foreign equipment.

On equipment, Tuojing Technology (拓荆科技) topped out its Shenyang high-end semiconductor equipment base on August 10, a near-18-billion-yuan project with planned capacity of 1,000+ tools per year for PECVD, SACVD, and HDPCVD thin-film deposition ⁴. The company says its tools have been deployed in roughly 100 domestic chip lines with cumulative wafers processed around 600 million. This is a concrete scale-up for a deposition specialist, not a lithography breakthrough; the gap in EUV/DUV lithography remains the binding constraint. Still, it shows the provincial-equipment track is adding industrial capacity even as central policy stays silent.

Provincial governments continue to drive the cluster model. Jiangsu held an integrated-circuit "6+6" special meeting on August 4, chaired by Governor Liu Xiaotao, calling for support for basic materials, core devices, advanced processes, and talent, and for a three-level (province-city-county) coordination with fiscal and financial tools ⁵. This joins Hubei's "Plane Tree" meeting and Liaoning's alliance as the known state-track signals; no national chip law or central directive has surfaced. The pattern remains: Beijing lets provinces and industrial capital push, while the center stays out of the news cycle.

The cost environment is shifting fast. Memory and processor prices are rising: SK Hynix DRAM ASP jumped ~65% QoQ in Q1 and ~30% in Q2; NAND rose ~75% and ~55% in the same quarters; Huawei's Yu Chengdong said memory price hikes could force large phone price increases ⁶. Nvidia AI-chip prices are reportedly rising ~17% ⁷. Meanwhile PCB leader WUS reported H1 net profit up 73.7% on AI demand, with 32-layer-plus PCB shipments up 190.8% and industry export revenue up 27.6% ⁸. This is the two-sided effect of the AI boom: it lifts the whole domestic chain but also raises the cost base for self-reliant products like Xiaomi's.

The structural position is unchanged in one dimension — design competes at the top tier, leading-edge fabrication remains external — but the foundation under that design is widening. Watch whether SMIC/Hua Hong margins translate into leading-edge capex, whether Tuojing's 2028 base becomes a hub for other deposition or lithography tools, and whether CXTMLPDDR6 supply expands beyond Xiaomi. The next concrete signals are SMIC's Q3 earnings and capex guidance, Tuojing's equipment qualification announcements, and any provincial follow-up documents from Jiangsu's meeting. For now, the Chinese chip story is no longer single-track: it is design-plus-foundry-plus-equipment, moving at different speeds but in the same direction.
