- China is trying to catch up in high-bandwidth memory (HBM) technology to improve AI chip performance. They need to overcome several challenges to advance beyond their current HBM2 level.
- CXMT, China's leading memory manufacturer, is facing difficulties due to export controls limiting access to advanced manufacturing tools. This could hinder their ability to produce competitive memory products.
- While some aspects like etching tools are less of a barrier, significant hurdles remain in the packaging and base die production. Without breakthroughs in these areas, China’s HBM progress may continue to lag behind global leaders.
