🧠 2. SDV (Software Defined Vehicle)
Key Focus: Zonal architecture, OTA updates, centralized ECU
- Vehicle control systems are shifting from domain-based to zonal-based architecture
- OTA (Over-the-Air) updates enable real-time software upgrades and cybersecurity enhancements
🤖 3. Autonomous Driving & ADAS Components
Key Focus: LiDAR, radar, V2X, sensor fusion
- MEMS and flash LiDAR are entering mass production
- Long-range radar + AI camera fusion modules are being developed for L2+ autonomous systems
- V2X modules enhance vehicle-to-infrastructure communication
📦 4. MLCC Demand Surge
Key Focus: High-capacity MLCCs, EV-specific components, global CAPEX expansion
- EVs require thousands of MLCCs per vehicle, especially in BMS, inverters, and chargers
- Major suppliers (Murata, TDK, Yageo) are expanding production capacity
⚡ 5. SiC Power Semiconductor Modules
Key Focus: 800V inverters, SiC MOSFETs, GaN hybrid modules
- SiC modules are now standard in Tesla, GM, Hyundai EV platforms
- High-speed, low-heat hybrid ICs are under joint development globally
🌍 6. Global Supply Chain Strategy
Key Focus: IRA compliance, localization, material independence
- Korean, Taiwanese, and Japanese firms are expanding production in the U.S. and ASEAN
- Battery and semiconductor supply chains are being restructured to reduce China dependency
