Van Zant grounds the reader in economics through —the percentage of good dies per wafer. He distinguishes:

: Detailed look at crystal growth (Czochralski method), wafer preparation, and surface contamination control.

After exposure, the resist is developed. The pattern must be transferred. Van Zant contrasts wet etching (chemical baths, isotropic, undercuts the mask) with dry plasma etching (anisotropic, straight sidewalls). For modern chips, only plasma etching works. Van Zant explains the physics: a plasma generates reactive radicals (e.g., CF4) that chemically react with silicon, while ions bombarding vertically accelerate the reaction, creating high-aspect-ratio trenches. The wafer is coated with a light-sensitive liquid

Automated electrical testers press microscopic needles onto the chip contacts to verify functionality. Defective chips are marked.
