China’s CXMT faces a major disaster? An unsettling semiconductor outlook | Special with Kim Jung-ho, Kang Jun-young and Cho Hyun-seung
An independent exercise, not a statement by the video creator or verification of every claim in the video.
How does surviving on high prices differ from yield competitiveness?
Assume total wafer-processing cost is KRW 1 million and a wafer contains 100 potential dies of identical size and performance. An 80% yield gives 80 good dies at KRW 12,500 each, while a 50% yield gives 50 good dies at KRW 20,000 each. A selling price of KRW 25,000 exceeds processing cost in both cases, but at KRW 18,000 the low-yield case falls short by KRW 2,000 per die. The calculation separates continued production during high prices from cost competitiveness that survives a price decline.
Check for yourself
- Has cost per good die improved even after removing the selling-price increase?
- Do the compared yields refer to the same product, process stage and acceptance criteria?
Limits of application
This hypothetical is not an estimate of any Chinese company’s yield, cost or profit. It compares processing cost only, excluding design, research, selling, packaging, testing, yield-dependent rework and product-price differences. Costs already included in total wafer processing should not be deducted twice.
- What to look for
- See how equipment and talent access, profitability during high memory prices, domestic demand and financing interact in China’s semiconductor catch-up.
- Why it matters
- Separating yield, product qualification, funding and recovery capability instead of comparing node labels alone helps distinguish technology development from a sustainable business.
Timeline
6 segmentsKim Jung-ho describes restricted lithography-equipment access as a major constraint on China’s catch-up. However, claiming that advanced nodes are entirely impossible without EUV is too absolute: DUV multiple patterning must be assessed separately for feasibility, process complexity, cost and yield. DUV export controls also vary with equipment type and transaction parties.
