Yield Improvement Through Data Analysis using TIBCO Spotfire

  1. 1. Yield Improvement Through Data Analysis using TIBCO Spotfire Presented by: Andrew Choo Sr. Yield Engineer
  2. 2. Introduction to TriQuint • Design and Manufacture of high-performance radio frequency (RF) components for wireless communication. • Cell Phones, WiFi, Military and even the Mars Rover • Technology is based on Gallium Arsenide (GaAs) semiconductor. • Spin-off from Tektronix in 1985. • Currently about 2700 employees worldwide. • Manufacturing sites in Oregon, Texas, Florida and Costa Rica. • NASDAQ ticker: TQNT Confidential & Proprietary Connecting the Digital World to the Global Network®
  3. 3. Manufacturing Operations • Wafer Fabs: Clean rooms for processing 6” wafers, Building “chips” on wafers, layer by layer • Test: Electrical testing of test structures (Process Control Monitors) and chips on wafer (Diesort) • Thin and Saw: Wafers are thinned to thickness of paper and cut up using diamond saws • Product Final Test: “Chips” are assembled into final products and tested for performance. • Manufacturing Output: Products and Data! Generate about 60 Gbytes per week… Confidential & Proprietary Connecting the Digital World to the Global Network®
  4. 4. KEY Manufacturing Metric • YIELD = Percentage of products meeting TriQuint quality and performance standards that can be delivered to customers. • Primary driving factor for top line revenue • With complex manufacturing processes, there are 10,000 ways to fail and it becomes critical to react quickly and correct problems that affect Yield. • When Yield excursions occur: – Need to extract and analyze large amounts of data. – Determine ROOT CAUSE. – Implement corrective actions to eliminate future occurrences.

  5. 5. Data Analysis • TIBCO Spotfire has become TriQuint’s standard tool for Data Analysis. • Deployment started in 2004 with 5 user license. • Current deployment is World Wide. • Integrated with production databases for ETL and Data Mash-ups. • Used in “live” mode during meetings to view and analyze data. • Build and Deploy “Analysis Dashboards”: • Preconfigured analysis files for different types of data. • Data Drill Down methodology with load data on demand • Flexible, insightful analytics for everyone. Confidential & Proprietary Connecting the Digital World to the Global Network® Let’s Take a Look! …
  6. 6. Benefits • Huge improvement in turn around times in analysis of problems from weeks to hours. • Shift in how problems are solved and the way engineering approaches data analysis. – Focus on the problem and what the data means, not where and how to get the data. • Achieving Yield Goals: – We set a goal of > 96% for product yields in 2006. We met and exceeded this goal by 2008. – Recognized significant revenue from yield improvement efforts. http://www.triquint.com/contacts/press/newsanddiscoveries_detail.cfm?id=221 “Make decisions based on Data” David Pye, Operations VP $1.00 chip * 10k chips wafer 2k wafers month* = $1.2M/qtr2% Yield* Yield Improvement translates to Cost Savings.
