IGBT is the core device of power conversion, which is composed of bipolar triode and MOSFET. It is suitable for converter systems with DC voltage of 600V and above. At present, the global IGBT market pattern is mainly dominated by overseas power semiconductor manufacturers such as Infineon, ansenmey, Italy France semiconductor, Fuji Electric, Mitsubishi Electric, especially in the medium and high-end market. However, even the faucet is now "off the chain".

Just now, according to the latest news, the IONIQ 5 model of Hyundai Motor Co., Ltd. of South Korea may face shutdown for a period of time, because Infineon, the world's largest automotive semiconductor company that supplies power module chips (IGBT), has recently produced a large number of unqualified products.

The source pointed out that Infineon found defects in IGBT chips produced from early April to early June this year, and the company gave up all automotive chips produced during this period, which were originally planned to be shipped to Hyundai Motor in the middle of this month.

It is reported that the specific situation of the above problem chip refers to that Infineon has produced a large number of defective products in the process of improving the existing nitrogen ion implantation process and switching to the latest aluminum ion process. Specifically, the problem of the product is produced in the process of injecting aluminum ions rather than nitrogen ions into the battery. In the latest manufacturing process, aluminum ions have replaced nitrogen to power rechargeable batteries.

For this reason, the production time of Hyundai's all electric crossover model IONIQ 5 is likely to be postponed. Moreover, this time is not short.

It is not difficult to find that it takes about three months to produce an IGBT chip, while it takes another month to reassemble them into a power module. Therefore, the chip supply interruption is unlikely to be resolved before mid October, and the waiting time for IONIQ 5 buyers should be more than a year.


Obviously, due to the interruption of chip supply, Hyundai's plan to speed up production in the second half of the year (July to December) will be affected. However, in order to avoid the production interruption of IONIQ 5, the company is looking for alternatives to purchase automotive semiconductors from other semiconductor enterprises.
