Huawei Ascend 910C reaches 40% yield on SMIC 7nm, marking profitable production milestone
Huawei's Ascend 910C chip, manufactured by SMIC using its 7nm DUV process, achieved a 40% yield rate in early 2025, marking the first time the Ascend production line became profitable. The improvement from 20% yield in September 2024 demonstrates SMIC's progress with multi-patterning techniques and older lithography equipment.
- Ascend 910C yield improved from 20% in September 2024 to nearly 40% by early 2025
- Huawei production ramped from zero units in 2024 to 100,000 planned for 2025
- Company aims for 60% yield to reach industry standards
- Success achieved using only DUV lithography, without access to ASML EUV tools
