The OEM has deliberately entered into a single-sourcing contract with the tier 1 supplier and the latter has usually also concluded a single-sourcing subcontract with its respective semiconductor manufacturer. ASIC chips (application-specific integrated circuit)/design-in chips were often used in the development process, which were only produced individually by the semiconductor manufacturer for this order. If the supply chain now becomes unstable – as it has in the last three years – this “2-tier monopoly dependency for a limited period” comes to light.
