    Process your Results with Unsurpassed Flexibility and Functionality

    DeltaPsi2 software provides advanced features to process ellipsometric data simply and reliably.

    • Customizable user interface
    • Data manipulation
    • Advanced features for graphic manipulation screen
    • Standard Windows® clipboard transfer
    • Import/export package function
    • Automatic reporting
    • Output description for automatic calculation of specific values after modeling

    User Friendly Operations

    Three user modes for research, fab and quality control are designed to provide user friendly operations.

    • The research mode mainly uses drag and drop function from the left side of the treeview to the right side of the modelling area.
    • The fab mode provides a fully automatic operating environment based on automatic, push button recipes that fully automate the analysis sequence: acquisition + modelling + mapping + results.
    • The quality control mode, which is the new Auto Soft software package, is designed to provide easy operations of ellipsometric analysis.

    Simple Automatic Recipes

    recipe fully automates data acquisition+modeling+mapping+results, which facilitates routine thin film analysis.

    The design of the software allows the user to define several acquisition routines and models in a single recipe as well as several groups of points in a single grid.

    • Recipe procedure.
    • Fitting procedure.
    • Acceptance criteria for integrated quality control.
    • Conveniently access to recipe steps and original files for processing / reprocessing.
    • Statistical analysis
    • Standardized visualization of mapping results on semiconductor wafer and glass panels
    • Autofocus and pattern recognition functions.
    • Advanced communication protocols (RS232, TCP/IP)
