Browser-first wafer map visualization for semiconductor test data
One wafer, three test channels, spatial ring and quadrant stats, Plotly click drill-down.
2×2 grid of wafers from a lot. Shared colour scheme, per-wafer yield stats.
One map per bin showing how many wafers had each bin at each die position across a six-wafer lot.
Same CSV rendered four ways with increasing geometry input — shows how missing parameters are inferred.
Upload any CSV. Column mapping, per-wafer gallery, Pareto chart, Web Worker processing.
Consumes wafermap as a local npm package via Vite. Starting point for React, Vue, or Svelte projects.
Low-level reference: all plot modes, rotate/flip, probe path, reticle overlay, ring boundaries.
