Python module for working with STDF files
Shot & Wafer map for semiconductor
STDF to Wafer Bin Map utility written in Python
STDF is Standard Test Data Format for ATE(Automatic Test Equipment). A library for Read and Write STDF V4 File.
Interactive wafer map visualization and yield analysis for semiconductor test data. Rendering, spatial statistics, failure clustering, lot-level trends, and reticle analysis — pure ES modules, no dependencies.
Make large ATE .stdf(.gz) files accessible (mostly PTR "RESULT" data, binning, test limits). Optionally fast binary import into Octave, with emphasis on working with multiple datasets.
