TEA Systemsí products deliver vendor independent analysis for yield enhancement, process control, systematic error elimination and characterization. Weir product capabilities are unmatched in the industry. Modeled Field Rotation - Vector Raptor

Data is imported and stored in an open format Microsoft Excel workbooks providing full user access to raw, modeled and derived matrices. Automated data reports can be customized and delivered in text or html formats.

All products offer enhanced data culling when handling either noisy data or localized disturbances in the process. Culling is both automated and open to user manual control. Data culling can be performed through analysis specific controls and mouse-selected, point-and-click removal or area, wafer, field, site and point specific members.

Proprietary mathematical, graphic and modeling engines are uniquely tuned to the highly systematic data populations found in semiconductor manufacturing. Regressions use TEA System's proprietary Singular Value Decomposition, adaptive modeling to provide un-matched accuracy in deriving the control and tuning components that you need to control your process and yields.


Wafer, field or lot vector and contour interactive graphics are linked to the TEA Systems Lot model for full object drill-down capability., 2D, 3D, contour, XYgraphs, Histograms, Trend plots, Curve-fitting, population density curves, BoxPlots and many more graphics are easily created using your mouse and our graphic interface. Point-and-cick dataProcess Window for Side Wall Angle measured featured. analysis tools provide basic and advanced statistics and precision analyses.

All analyses can be Weir Macro embedded using our mouse-driven interface to provide two-click data modeling/trending with Weir DM and automated, non-interactive analyses from Advanced Process Control (APC) and factory control systems using Weir DMA.

Data *

All Analyses use the Weir Standard Format for data that is stored in Microsoft Excel workbooks. Workbooks are also used to store reports and additional analysis-generated data such as focus & dose uniformity. Reports can be extracted in html format for internet or web reporting. External metrology data need only be imported into the Weir Workbook the first time it is used. Follow-up analyses use the Weir Workbook format.
