Panel on Substrate Needs: The User Perspective with five Substrate End Users
Summary: Substrates are required to support high-performance compute and telecom, automotive electronic, consumer, defense, and medical applications. Regardless of the interposer technology, silicon or redistribution layer substrates, attachment to a build-up substrate creates the final package. There is also interest in continuing direct chip attach to a high-density organic substrate, with options including a glass core. This panel provides substrate user perspectives on feature size requirements today and tomorrow. Highlighted is a discussion on requirements to be a substrate supplier in the different applications. Reliability requirements and any special substrate needs are described. Consideration of geographic location for substrate suppliers is addressed.
Session on Emerging Substrate Technologies
Summary: This session will focus on Novel Substrate Technologies that have the potential to bring back Substrate Technologies to the USA. The first talk in this session will introduce Wafer-Level Substrates and contrast this against the current incumbent Panel-Level Substrates with existing installed base in Asia. The second talk in this session will introduce novel substrate finishing structures to enable die bumping on substrates with a <10um pitch. The final talk in this session will introduce novel technologies to enable UCIe connectivity between dies directly on substrates without any Si interposer or RDL interposer.
