South Korean suppliers ramp up hybrid bonding R&D beyond HBM5

What happened

South Korean suppliers are ramping up R&D for hybrid bonding technology to support HBM5 and higher stack layers. As HBM stack layers increase, requirements for chip-to-chip bonding accuracy and signal transmission efficiency become more demanding. Bullish on advanced packaging tech breakthroughs, but no direct impact on spot prices in the short term.
