PDF Solutions, Inc. provides infrastructure technologies and services for the design and manufacture of integrated circuits (IC) in Asia, the United States, and Europe. It offers manufacturing process solutions that include process research and development, and process integration and yield ramp; volume manufacturing solutions; and design-for-manufacturability (DFM) solutions, such as logic DFM, circuit level DFM, memory DFM, and pdBRIX physical IP solutions. The company also offers Characterization vehicle (CV) infrastructure, which includes CV test chips, pdCV analysis software, and pdFasTest electrical wafer test system; Yield Ramp Simulator software that analyzes an IC design to compute its systematic and random yield loss; and Circuit Surfer software, which estimates the parametric performance yield and manufacturability of analog/mixed-signal/RF blocks. In addition, it provides pdBRIX platform, which includes software for identifying and developing a set of physical IP building blocks that are tailored to a given manufacturing process and target product application; dataPOWER YMS platform that collects yield data, loads, and stores it in an integrated database and allows product engineers to identify and analyze production yield issues; FDC software, which provides fault detection and classification capabilities to identify sources of process variations and manufacturing excursions by monitoring equipment parameters; and YA-FDC tools that allow online modeling to create real-time virtual measurements of final product attributes during processing. PDF Solutions sells its technologies and services through direct sales force and strategic alliances to integrated device manufacturers, fabless semiconductor design companies, and foundries in the microprocessors, memory, graphics, image sensor solutions, and communications segments. The company was founded in 1992 and is headquartered in San Jose, California.
