stdf

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.

Desktop and browser wafer map viewer for semiconductor test data — Tauri v2, Rust/WASM parsers for STDF/ATDF/CSV/JSON/Parquet, wafermap rendering

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.
