According to reports, foundries TSMC, UMC, and VIS have signed 2022 to 2023 foundry agreements with Infineon and other automotive chip makers.

An industry insider pointed out that before the shortage, the service provided by the foundry to the automotive chip suppliers was “Just in Time”(JIT). After experiencing a severe shortage for a year, they are now beginning to book foundry capacity in advance to ensure supply.

The source further stated that automotive chip suppliers have gradually realized that the shortage is a structural problem, so they have now begun to build inventories and reserve fab capacity in advance.
