PDF Solutions, a provider of yield improvement technologies and services for the IC process life cycle, has brought to market the Exensio-Test software for semiconductor companies. Exensio-Test, now deployed and available worldwide, enables semiconductor manufacturers to improve the efficiency and quality of their testing, indicated the company.

The latest offering combines technology gained through the acquisition of key semiconductor software assets from Salland Engineering entities with the Big Data capabilities of PDF's Exensio Platform. This module provides test floor operation, adaptive test and analysis technology that produces diagnostic and predictive information during test, assembly and packaging operations, stated the company. This information is critical to optimising customers' test operations, productivity and yields.

The Exensio-Test solution claims to offer significantly reduced test times through the implementation of real-time adaptive test algorithms. This reduction is required for advanced products and processes with stringent PPM (parts-per-million) defectivity requirements. It also provides reduced test time through optimisation of test probe setup selection and simultaneous tester/prober recipe optimisation, stated the company.

Additionally, Exensio-Test delivers increased test productivity and insight into test floor efficiency across a variety of subcontractor and in-house test facilities with real-time alarms and actions. It also enables linking of manufacturing data to root causes seen in wafer sort and final test, through utilisation of advanced analysis, data mining and modeling features, as well as implementation of predictive alarms. Likewise, it affords co-optimisation of overall equipment effectiveness (OEE), UPM, productivity and yield, when paired with PDF Solutions' scribe CV technologies. This enables customers to optimise adaptive test, the company added.
