The action should establish a supply chain data platform, as a digital twin of the semiconductor supply chain, which should:

• Gather secure, anonymized data shared by companies, coming from both upstream and downstream industries.

• Possibly make use of an existing digital reference14 of the semiconductor supply chain (based on semantic web technologies).

• Be managed by a trusted intermediary and hosted on a trusted data sharing infrastructure (potentially leveraging secure Multi-Party Computation).

• Provide access to each participating company (providing its data) to its own data and aggregate anonymised data.

The action should support the data gathering from the companies involved.

The action should support a global mapping of the semiconductor value chain, as regards to the capabilities and the products of each main company and its supply chain relationships.

The action should also support conducting stress tests of the supply chain and develop risk analysis of the EU semiconductor supply chain. Finally, the action needs to support issuing early warnings and recommendations for proactive measures to the Commission and Member States to avoid any potential crisis activation according to Article 23 of the Chips Act.
