PDF Solutions (PDFS)

Its technology is designed to collect and connect large amounts of data generated during chip design, wafer fabrication, assembly, packaging, and testing. Semiconductor production is highly complex, and small process variations can affect yield, reliability, and cost. PDF Solutions helps customers identify patterns in manufacturing and test data, diagnose performance issues, and make better decisions across the product lifecycle.

The company’s offerings include proprietary software platforms, advanced analytics, electrical measurement hardware, design-for-manufacturing tools, physical intellectual property used in integrated circuit design, and professional services. Its Exensio platform is widely associated with manufacturing and test data analytics for semiconductor companies seeking to unify information from different tools, factories, and suppliers.

PDF Solutions occupies a specialised position in the semiconductor supply chain because it is not a chipmaker or equipment vendor; it focuses on the data layer that supports process control and continuous improvement. Demand for its solutions is tied to the industry’s need for higher yields, faster ramp-ups, and better visibility as chips become more advanced and supply chains more distributed. Its business is influenced by semiconductor capital spending, customer product cycles, software adoption, and the growing strategic importance of data-driven manufacturing.
