According to industry sources, international IDM, including Infineon and stmicroelectronics, continues to step up the production of automotive, industrial control and network chips to meet the growing demand, and outsource more back-end operations of such chip solutions to partners in Taiwan Province. IDM still uses mature process nodes and traditional packaging technology to manufacture automotive, industrial and network chips, but it needs high-end testing technology to ensure performance stability. According to sources, this has prompted ASE Technology, King Yuan Electronics (KYEC), TeraPower Technology, Sigurd Microelectronics and Ardentec to greatly improve their high-end testing capabilities to conduct time-consuming tests on these chips. Sources pointed out that although their overall business operations will hardly be affected by the significant drop in demand for mobile phone chips, the back-end companies will still be able to maintain stable revenue performance in terms of product portfolio improvement of international IDM and major IC design companies in Taiwan Province. The source continued that, in view of the increasing demand for smart factories, industrial automation systems, electric vehicles and self-driving vehicles, the demand for MCU, power semiconductor and power management IC (PMIC) in automotive and industrial applications will continue to rise in the long term. With the increasing popularity of 5G network and AIoT technology, the demand for more efficient cloud computing and edge computing chips, high-density and energy-efficient power chips and third-generation semiconductor materials such as GaN and SiC will also increase. According to sources, the growth has significantly improved the revenue performance of IDM and major IC design companies. For example, Infineon has raised its revenue forecast for 2022 from 13 billion euros to 13.5 billion euros, and its profit margin is higher than the single-digit level originally estimated. ST also estimates that its annual sales will increase from USD 14.8-15.3 billion in 2022 to USD 20 billion in 2025-2027.
