Acuity is defined as the capacity of the eye to see fine detail, measured by determining the finest detail that can just be detected.
Test Acuity Solutions (TAS) develops and deploys leading-edge, proprietary software focused on exposing device performance variability across the semiconductor back-end manufacturing processes, to automate manufacturing quality and facilitate equipment utilization and process improvements throughout the manufacturing process
Our solutions have repeatedly proven that no trade-off is automatically necessary between device quality and the cost of test.
- Die grading and die disposition technology based on performance variability analysis of Wafer Fab and Test Data
- Wafer level disposition technology based on regional spatial and automatic pattern detection analysis
- End-to-end connectivity using open-standards enabling Adaptive Test and Adaptive feed-forward, Single Device Traceability (SDT) and Intelligent Recall through technology partnership with Kinesys Software.
- Corporate-wide test quality and efficiency standards throughout the semiconductor product lifecycle
Test Acuity Solutions (TAS) patented and patent pending proprietary technologies exposes device marginality and enables next generation feed-forward and adaptive test strategies that are being recognized industry-wide as necessary technologies to achieve next generation cost and quality models.
Our solutions provide the technology to enable downstream process flow decisions through the application of adaptive feed-forward methodologies as represented in the International Technology Roadmap for Semiconductors (ITRS).
