1. Band Theory: Metallic Bonding Photoelectron Spectroscopy

2. Band Theory: Metallic Bonding Photoelectron Spectroscopy

4. Band Structure for Periods 4-6, Group 1A – 2B http://employees.oneonta.edu/viningwj/sims/metallic_bonding_band_theory_s.html

5. Conduction in Solids

6. Silicon Semiconductors

8. Chip Fabrication 1.Make really, really pure Si 2.Add impurities in a controlled way (doping) SiO 2 (s) + 4 HCl  SiCl 4 (l) + H 2 O(l) SiCl 4 purified by distillation. SiCl 4 + 2 Zn  Si + ZnCl 2 Si now 99.9% pure. Zone refining used to purify to 99.99999% pure.

9. Circuit Components Diodes Transistors

10. Doping 1.Apply coating 2.Illuminate through mask 3.Dissolve illuminated areas 4.Add gas phase dopant 5.Repeat
