The Ring on the Wafer Map: Inside a Semiconductor Fab
How chips are made after lithography: wafers and transistors, the cleanroom and ultrapure utilities, deposition (CVD, ALD, epitaxy, damascene copper), plasma etch, implantation, CMP and cleaning, metrology and inspection, yield models, fab economics and Rock's law, the foundry model, TSMC Arizona and the CHIPS Act, real fab incidents, advanced packaging, and fab data. Cross-references: EP02 (EUV lithography), ep163 (caches).
