Technical bottleneck
- Bottleneck type: process integration / yield
- Technical constraint: nanosheet/RibbonFET integration, backside power, patterning, deposition/etch complexity
- Economic constraint: high R&D/capex; few foundries can execute; external-customer validation critical
Adoption
- Driver: AI ASIC/CPU/GPU demand, foundry competition, Intel 18A/14A, TSMC N2
- Blocker: node delays, external-customer failure, yield issues
