1. Yield Improvement Through Data Analysis using TIBCO Spotfire
Presented by: Andrew Choo Sr. Yield Engineer
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. 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. 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. Confidential

5. Data Analysis TIBCO Spotfire has become TriQuints 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 Lets
Take a Look!
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.
