TEA Systems Announces
Release of
Weir 4.0 Integrated Process Analysis Software
Allentown, PA (USA). May 1, 2006 --
TEA Systems Corporation, a process setup and analysis services
provider for the semiconductor industry, announces the first industry wide release of it's new suite
of Weir 4.0 software. The Weir Software Suite is a family of windows-based tools
that provide an integrated interface for all of the engineering and
manufacturing sub-90 nanometer node analysis needs.
Previously the engineer had to turn to many software packages to provide functions such as process window analysis, tool calibration, focal plane uniformity, data visualization, exposure characterization, setup, lens characterization, lot-gating, thermal mapping and data mining functions. Weir 4.0 provides all these functions plus additional analyses such as reticle design qualification, reticle process capability, reticle feature extraction from wafer data, dose-mapping, exposure latitude mapping, film response, process comparison, precision response, covariance matching tools and spatial modeling of systematic tool, process, wafer and lens errors.
The Weir Software suite uniquely imports any simulation, metrology or process-tool specific data and restructures it into a Lot-model object. The Lot-model structure is a process-systematic hierarchy that provides drill-down capability for all empirical data analyses. Weir's point-and-click interface supports full interactive drill-down data manipulation and modeling. Reports and an "open" data structure are enhanced by many user-customizable, interactive graphics that include 1D, 2D and 3D control surface contours, XY charts, histograms, trend charts, box plots, population density plots, vector, range and curve fitting.
Automation needs for the use of complex engineering analysis sequences in production applications are provided by the macro-encapsulation tools of Weir DM. Weir DM's interactive mode presents simple "two-click" access to any complex user-customized analysis. Full-automation is supported through external module calling for any process control or factory automation modeling. Results summarize to customized graphics and statistics as well as historic trend-charts. Automation outputs can be sent to text files, Excel Workbooks and "html" web reports.
Terrence Zavecz, president of TEA Systems commented, "This product provides a previously missing link between design simulation and production and testing. We've used and tested this software in-house for our consultation and support services for over three years. Selected partners have purchased it and provided valuable feedback from their use of individual modules. With the industry-wide release of Weir 4.0 we now can present a unique product for both classic analyses and proprietary modeling that provides a single analysis tool for control of the most advanced production processes."
Applications include
:- Reticle validation and qualification in the wafer process or mask house.
- Reticle evaluation for full-field process window capability
- Design qualification for Optical Proximity Correction and Phase Shift.
- Process, lens and tool characterization
- ARC, film and immersion lithography characterization and matching
- Process and tool setup with full-field process window uniformity calculation
- Focus budget derivation from FOCAL, Z-spin, PGM and PSFM Reticle data (Weir PSFM) as well as Bossung matrix studies (Weir PW)
- Full-field dose, exposure latitude, focus and depth-of-focus mapping.
- Enhanced full-field isofocal and aberration analysis response.
- Covariance and precision matching for thermal, yield, ECD and lithographic performance
- Metrology, process, tool and scan subassembly precision response.
- Validation of simulation and Design for Manufacturing calculations.
- Full automation of any of the above applications from any metrology system.
