Dawson Lee | Silicon & Infra Alpha(@LiDaosen):1/5 The expert call confirms Intel ( $INTC )EMIB-T assembly yield sits at 40.5%. While eliminating full-wafer silicon interposers cuts theoretical BOM cost by ~40% vs CoWoS-L, scrapping 60% of completed packages destroys host wafer economics. A 6x CTE mismatch between silicon bridges (2.6 ppm/°C) and organic ABF (16 ppm/°C) causes warpage during bonding. CoWoS-L retains 80%+ share through 2028.
