Search every verified Michael Slessor interview, podcast appearance, and on-the-record quote — each transcript cross-checked by AI and human review to confirm speaker identity. Michael Slessor, President and CEO of FormFactor, has discussed the company's role in semiconductor testing and measurement across several recent appearances. In a May 2026 podcast interview, he addressed the testing economics of HBM4 and HBM5 memory stacks, noting that higher stacks increase the risk of total failure if a single die is defective, which drives demand for more intensive testing. He also described FormFactor's work on electro-optical probe cards for co-packaged optics, stating the company owns photonic IP and subcomponents for that effort. Slessor commented on FormFactor's divestiture of its China business, attributing it to U.S. export controls introduced in 2022 that restrict shipping advanced-node equipment to China. In an October 2025 podcast, Slessor described advanced packaging, chiplets, and heterogeneous integration as a "mega trend" driven by the difficulty of continuing traditional transistor scaling. He emphasized the importance of testing individual chiplets before assembly to avoid costly failures in advanced packaging stacks. Slessor also discussed the growing role of geopolitics in the semiconductor industry, stating that it has become the most challenging environment he has operated in as an executive, and expressed personal views on the potential damage of trade restrictions to the U.S. semiconductor supply chain. He has also highlighted the increasing technical demands of probe cards, including their role in enabling hybrid bonding and other advanced packaging architectures.
