DB HiTek Delays SiC and GaN Foundry Ramp Amid Technical, Market Challenges - thelec.net

DB HiTek's decision to delay its SiC and GaN foundry ramp-up reflects the complex challenges facing the semiconductor industry in power device manufacturing. While SiC and GaN materials offer superior... Read original →

DB HiTek’s delay in scaling SiC and GaN foundry operations reveals a critical gap between wide-bandgap semiconductor promise and manufacturable reality. Technically, subpar 8-inch SiC epitaxy yields and unresolved GaN-on-Si thermal issues hinder cost-effective automotive and renewable energy adoption. Regulatory shifts—like the U.S. CHIPS Act’s domestic-content rules and EU carbon border taxes—amplify capex risks for non-aligned foundries. Competitors like TSMC and STMicroelectronics are locking in long-term deals with Tesla and Infineon, marginalizing second-tier players. Over the next 18 months, only IDMs or foundries embedded in vertical ecosystems (e.g., Wolfspeed with GM) will sustain momentum; pure-play foundries without state support or process breakthroughs risk exclusion from high-margin power markets.
