Action Guidance

Action Steps

1

Monitor JEDEC SPHBM4 standard approval progress and final specs

2

Evaluate alternative packaging suppliers (organic/glass substrates) capabilities

3

Invest in chip design and packaging tech supporting new standard, partner with early adopters

6-12 months; standard expected approval early 2027, mass production 1-2 years
R&D budget, packaging engineering team, supply chain relationship management
Technology immaturity, standard delays, resistance from existing CoWoS ecosystem

Key Signals

Extended Impact Analysis

Could shift AI packaging from scarce wafer-level to common substrate packaging, altering market competition, lowering entry barriers, and impacting TSMC's packaging revenue.
