# The Chinese Native Chip Fabrication Stack

Driven by Western sanctions and exposed vulnerabilities in global maritime supply chains, China is aggressively pursuing a 'native' chip fabrication stack — controlling every input locally.

The speaker highlights that China is pushing hard to develop domestic helium production, with a plant in Guangdong recently achieving the **6N (99.9999%) purity certification** required to supply [[entity-asml]] lithography machines. While currently small (~1.2 million cubic meters), this domestic capacity is scaling rapidly.

If China combines domestic helium production with secure overland energy from Russia (via [[concept-power-of-siberia-2]]), it will possess a structurally resilient semiconductor supply chain. This would allow Beijing to:

- Control its own cost of compute.
- Deploy cheap AI inference at scale.
- Gain a strategic advantage over Western-allied nations reliant on fragile maritime imports.

See [[claim-geopolitical-compute-shift]] for the strategic implication and [[contrarian-conflict-helps-china]] for the contrarian framing.

**Enrichment caveat**: As of 2026, Chinese domestic helium covers <5% of national need, and SMIC fab yields lag TSMC by 20–30%. The stack is being built but is not yet operationally complete.
