  1. Silicon Computer Chips Review Band Theory Expand to Conductors/ Semiconductors/ Insulators Intrinsic vs. Doped Semiconductors n-type and p-type Semiconductors np Junctions and Circuit Elements Chip Fabrication

  2. Review of Band Theory

  3. Conduction in Solids

  4. Intrinsic Semiconductors

  5. Doped n-type and p-type Semiconductors

  6. Junctions Diode Transistor

  7. Chip Fabrication • Make really, really pure Si • Add impurities in a controlled way SiO2(s) + 4 HCl  SiCl4 (l) + H2O(l) SiCl4 purified by distillation. SiCl4 + 2 Zn  Si + ZnCl2 Si now 99.9% pure. Zone refining used to purify to 99.99999% pure.

  8. Doping • Apply coating • Illuminate through mask • Dissolve illuminated areas • Add gas phase dopant • Repeat
