LG Innotek is seeking to enter Tesla's AI semiconductor supply chain by targeting ABF-based FC-BGA substrate orders for the automaker's AI4 chips, intensifying its competition with Samsung Electro-Mechanics (Semco) across both autonomous driving and humanoid robotics hardware.

Tesla CEO Elon Musk has confirmed that the company's in-house AI5 chip has completed design tape-out and entered a critical pre-production validation stage. The move has drawn renewed attention from supply chains in Taiwan and South Korea as Tesla builds a scalable computing infrastructure for vehicles, AI training systems, and humanoid robots.
