DB HiTek's power-chip push hits delay as stakes rise

DB HiTek’s delay in scaling SiC/GaN power chips reveals critical gaps in defect control and epitaxial integration—hampering its 8-inch wafer yield ramp and disrupting EV OBC and solar inverter design cycles. Amid U.S. and EU subsidies favoring domestic wide-bandgap supply chains, DB HiTek faces dual pressure: restricted access to advanced equipment and lack of IDM-style vertical synergy, inflating compliance costs. TSMC and STMicroelectronics are capitalizing by locking in Tier-1 clients like Bosch and Infineon via CoWoS-R and intelligent power modules. If DB HiTek fails to secure substrate breakthroughs through joint ventures or licensing within the next 18 months, its strategic relevance in power semiconductors will evaporate, relegating it to a regional foundry for legacy nodes.
