In a move that signals a decisive shift in the global technology cold war, Beijing has informally implemented a strict 50% domestic semiconductor equipment mandate for all new chip-making capacity. This "window guidance," enforced through the state’s rigorous approval process for new fabrication plants, requires domestic chipmakers to source at least half of their manufacturing tools from local suppliers. The directive is a cornerstone of China’s broader strategy to immunize its domestic artificial intelligence and high-performance computing sectors against escalating Western export controls.
The significance of this mandate cannot be overstated. By creating a guaranteed market for domestic champions, China is accelerating its transition from a buyer of foreign technology to a self-sufficient powerhouse. This development directly supports the production of advanced silicon necessary for the next generation of large language models (LLMs) and autonomous systems, ensuring that China’s AI roadmap remains unhindered by geopolitical friction.
Breakthroughs in the Clean Room: 7nm Testing and Localized Etching
The technical heart of this mandate lies in the rapid advancement of etching and cleaning technologies, sectors once dominated by American and Japanese firms. Reports as of late 2025 confirm that Semiconductor Manufacturing International Corporation (HKG: 0981), or SMIC, has successfully integrated domestic etching tools into its 7nm production lines for pilot testing. These tools, primarily supplied by Naura Technology Group (SZSE: 002371), are performing critical "patterning" tasks that define the microscopic architecture of advanced AI accelerators. This represents a significant leap from just two years ago, when domestic tools were largely relegated to "mature" nodes of 28nm and above.
Unlike previous self-sufficiency attempts that focused on low-end hardware, the current push emphasizes "learning-by-doing" on advanced nodes. In addition to etching, China has achieved nearly 50% self-sufficiency in cleaning and photoresist-removal tools. Firms like ACM Research (Shanghai) and Naura have developed advanced single-wafer cleaning systems that are now being integrated into SMIC’s most sophisticated process flows. These tools are essential for maintaining the high yields required for 7nm and 5nm production, where even a single microscopic particle can ruin a multi-thousand-dollar AI chip.
Initial reactions from the global semiconductor research community suggest a mix of surprise and concern. While Western experts previously argued that China was decades away from replicating the precision of high-end etching gear, the sheer volume of state-backed R&D—bolstered by the $47.5 billion "Big Fund" Phase III—has compressed this timeline. The ability to test these tools in real-world, high-volume environments like SMIC’s fabs provides a feedback loop that is rapidly closing the performance gap with Western counterparts.
The Great Decoupling: Market Winners and the Squeeze on US Giants
The 50% mandate has created a bifurcated market where domestic firms are experiencing explosive growth at the expense of established Silicon Valley titans. Naura Technology Group has recently ascended to become the world’s sixth-largest semiconductor equipment maker, reporting a 30% revenue jump in the first half of 2025. Similarly, Advanced Micro-Fabrication Equipment Inc. (SSE: 688012), known as AMEC, has seen its revenue soar by 44%, driven by its specialized Capacitively Coupled Plasma (CCP) etching tools which are now capable of handling nearly all etching steps for 5nm processes.
Conversely, the impact on U.S. equipment makers has transitioned from a temporary setback to a structural exclusion. Applied Materials, Inc. (NASDAQ: AMAT) has estimated a $710 million hit to its fiscal 2026 revenue as its share of the Chinese market continues to dwindle. Lam Research Corporation (NASDAQ: LRCX), which specializes in the very etching tools that AMEC and Naura are now replicating, has seen its China-based revenue drop significantly as local fabs swap out foreign gear for "good enough" domestic alternatives.
Even firms that were once considered indispensable are feeling the pressure. While KLA Corporation (NASDAQ: KLAC) remains more resilient due to the extreme complexity of metrology and inspection tools, it now faces long-term competition from state-funded Chinese startups like Hwatsing and RSIC. The strategic advantage has shifted: Chinese chipmakers are no longer just buying tools; they are building a protected ecosystem that ensures their long-term survival in the AI era, regardless of future sanctions from Washington or The Hague.
AI Sovereignty and the "Whole-Nation" Strategy
This mandate is a critical component of China's broader AI landscape, where hardware sovereignty is viewed as a prerequisite for national security. By forcing a 50% domestic adoption rate, Beijing is ensuring that its AI industry is not built on a "foundation of sand." If the U.S. were to further restrict the export of tools from companies like ASML Holding N.V. (NASDAQ: ASML) or Tokyo Electron, China’s existing domestic capacity would act as a vital buffer, allowing for the continued production of the Ascend and Biren AI chips that power its domestic data centers.
The move mirrors previous industrial milestones, such as China’s rapid dominance in the high-speed rail and solar panel industries. By utilizing a "whole-nation" approach, the government is absorbing the initial costs of lower-performing domestic tools to provide the scale necessary for technological convergence. This strategy addresses the primary concern of many industry analysts: that domestic tools might initially lead to lower yields. Beijing’s response is clear—yields can be improved through iteration, but a total cutoff from foreign technology cannot be easily mitigated without a local manufacturing base.
However, this aggressive push toward self-sufficiency also raises concerns about global supply chain fragmentation. As China moves toward its 100% domestic goal, the global semiconductor industry risks splitting into two incompatible ecosystems. This could lead to increased costs for AI development globally, as the economies of scale provided by a unified global market begin to erode.
The Road to 100%: What Lies Ahead
Looking toward the near-term, industry insiders expect the 50% threshold to be just the beginning. Under the 15th Five-Year Plan (2026–2030), Beijing is projected to raise the informal mandate to 70% or higher by 2027. The ultimate goal is 100% domestic equipment for the entire supply chain, including the most challenging frontier: Extreme Ultraviolet (EUV) lithography. While China still lags significantly in lithography, the progress made in etching and cleaning provides a blueprint for how they intend to tackle the rest of the stack.
The next major challenge will be the development of local alternatives for high-end metrology and chemical mechanical polishing (CMP) tools. Experts predict that the next two years will see a flurry of domestic acquisitions and state-led mergers as China seeks to consolidate its fragmented equipment sector into a few "national champions" capable of competing with the likes of Applied Materials on a global stage.
A Final Assessment of the Semiconductor Shift
The implementation of the 50% domestic equipment mandate marks a point of no return for the global chip industry. China has successfully leveraged its massive internal market to force a technological evolution that many thought was impossible under the weight of Western sanctions. By securing the tools of production, Beijing is effectively securing its future in artificial intelligence, ensuring that its researchers and companies have the silicon necessary to compete in the global AI race.
In the coming weeks and months, investors and policy analysts should watch for the official release of the 15th Five-Year Plan details, which will likely codify these informal mandates into long-term national policy. The era of a globalized, borderless semiconductor supply chain is ending, replaced by a new reality of "silicon nationalism" where the ability to build the machine that builds the chip is the ultimate form of power.
