Final Inspection: Verification before the next layer is added.  3. Layering and Doping  Microchip Fabrication: A Comprehensive Guide by Peter Van

• Deposition: Creating thin films of silicon dioxide (SiO2) or silicon nitride via Chemical Vapor Deposition (CVD) or Physical Vapor Deposition (PVD).
• Photolithography: The art of printing circuit patterns. Van Zant explains steppers, scanners, and the chemistry of positive vs. negative photoresist in vivid detail.
• Etching: Removing unwanted material. He compares wet etching (using chemical baths) to dry etching (plasma/RIE), explaining the pros, cons, and safety hazards of each.
• Doping: Introducing impurities (Boron or Phosphorus) via Diffusion or Ion Implantation. His explanation of "channeling" and "annealing" is a must-read for any process engineer.
