Stratosphere Solutions Sets Sights on Design For Yield Market With Launch of StratoPro

- Stratosphere Solutions Inc., a startup providing yield improvement products, today announced that it is delivering silicon intellectual property (IP) tools, proven at sub-100 nanometer process technologies, for semiconductor manufacturers to accelerate process and design yield ramps. 
The StratoPro™ platform enables design for manufacturability (DFM) and design for yield (DFY) because it characterizes process variability using high-resolution measurements derived from unique silicon IP developed by Stratosphere Solutions. 

 “In a highly competitive environment, we are delivering mission-critical products that semiconductor manufacturers are rapidly adopting and willing to pay for,” affirms Robert (Bob) Smith, chief executive officer (CEO) of Stratosphere Solutions.  “We are the only company that provides a proven sub-100 nanometer silicon IP product for the fabs that delivers comprehensive data for characterizing variability.”

The Market
Yield is a critical consideration for the semiconductor industry because it drives cost, offers competitive advantages and shows process maturity.  Yield fallout due to process variability is a problem that both semiconductor manufacturers and designers must contend with in sub-100 nanometer process technologies.  Process variability can lead to undesirable shifts in electrical behavior that reduce the yield and/or performance of a design. Characterizing these parametric failure mechanisms using traditional approaches has become prohibitively expensive.

 DFM approaches are well understood and design flows are being put in place to ramp yields.  However, DFM does not fully address the parametric yield problem because it relies on deterministic physical and optical models.  Conversely, comprehensive yield analysis requires statistical information.  The semiconductor industry lacks both the statistical tools and models for ramping parametric yields, and the need is reaching critical proportions.  Statistical parametric characterization based on actual measured silicon data is key to comprehending and reducing design-related yield loss.

Stratosphere Solutions’ Approach
Stratosphere Solutions is delivering a silicon-proven platform that addresses parametric yield during both design and manufacturing.  It brings together three elements:

1. Comprehensive characterization of process variability using measurements derived from silicon
2. Analysis, quantification and modeling of yield based on process variability
3. Optimization of design performance using yield models
   

Stratosphere Solutions believes that yield must be managed through a holistic and collaborative approach that spans design and manufacturing.

The Product
The company’s first product, StratoPro, offers the combination of a silicon IP platform coupled with applications that characterize within-die device variability enabling parametric yield analysis.  Used for statistical process characterization, the platform offers a consistent architecture for process technology development and production environments.  Its architecture lowers yield ramp costs by dramatically reducing the amount of silicon area required per test structure while allowing large statistical sample sizes.  It is fully testable using standard parametric test hardware.
“New material systems and ever-shrinking critical dimensions in sub-100 nanometer process technologies have introduced a variety of new sources of parametric and systematic yield loss,” says Dr. Scott Thompson, a noted expert in semiconductor manufacturing and associate professor of Electrical Engineering at the University of Florida, Gainesville.  “StratoPro is ideally suited for providing critical within-die statistics of many important electrical metrics of process variability and parametric yield.”
Manufacturers can incorporate StratoPro IP on their test vehicle, manufacture it and test it using StratoPro test programs.  The measured output is incorporated into the manufacturer’s yield management system (YMS).  Out-of-the-box StratoPro analysis methods are integrated into the manufacturer’s YMS, producing robust variability analysis results.

StratoPro is available in both a full reticle version, typically utilized during early development and yield ramp, and a scribe line version, most useful for production monitoring.  Under development is a yield modeling environment that will leverage StratoPro and enable fabs to provide designers with comprehensive yield models without divulging trade secret information. More details will be available later in 2006.

Pricing and Availability
StratoPro is available now and is licensed per process node and fab site.  The U.S. list price starts at $350,000 for a perpetual license.  Term licenses are also available. Annual maintenance and integration services are extra.
