PDF Solutions, Inc. provides infrastructure technologies and services to enhance yield and optimize performance of integrated circuits (IC) in Asia, Europe, and North America. The company offers manufacturing process solutions; volume manufacturing solutions; and design-for-manufacturability (DFM) solutions, such as logic DFM, circuit level DFM, memory DFM, and Template physical IP solutions. It also provides 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 Template technology, which includes Library Analyzer software and IP for identifying and developing a set of layout patterns. In addition, the company offers Exensio enterprise-wide platform that enables sensor level and root cause diagnosis of yield and performance issues that impact manufacturing through building process models. Its platform consists of Exensio-Yield that collects yield data, loads, and stores it in an analysis-ready database, which enables product engineers to identify and analyze production yield, performance, reliability, and other issues; Exensio-Control that provide fault detection and classification capabilities for monitoring, alarming, and controlling manufacturing tool sets; and the Exensio Reporting and Automation module, which enables real-time execution of interactive reports, analyses, and dashboards. The company sells its technologies and services through direct sales force, solution implementation teams, and strategic alliances to integrated device manufacturers, fabless semiconductor design companies, and foundries in the microprocessors, memory, graphics, image sensor solutions, and communications segments. PDF Solutions, Inc. was founded in 1992 and is headquartered in San Jose, California.
