Industry Analysis
USI’s SiC chip-embedded packaging unveiled at PCIM Europe 2026 signals a strategic pivot from discrete power devices to system-level integration. By embedding SiC dies into ABF substrates with SSC and wire-bondless architecture, USI slashes stray inductance and thermal resistance—critical for 800V EVs and AI data centers. This disrupts the upstream ABF supply chain, pressuring material suppliers to develop thermally enhanced variants, while eroding Japanese dominance in thick-copper ceramic modules. Geopolitically, the approach reduces reliance on U.S. SiC epitaxy tools but exposes vulnerability if ABF exports face restrictions akin to Japan’s 2023 photoresist controls. Competing against Wolfspeed’s and Infineon’s chiplet-based SiC modules, USI leverages its EMS strength to avoid IDM capital traps. Within 18 months, this technology could become the de facto standard for onboard chargers and humanoid robot actuators, elevating Taiwan, China from a packaging subcontractor to an architectural definer in power electronics.
