Mosfet Theory of Operation and Fabrication

• mosfet transistor construction (from semiconductors)

• theory and operation

• effect of static electricity on MOS
• mosfet fabrication
  • Processes
    • growing oxide
    • application of photoresist (prebaking)
    • exposure to uv light
    • developer - etches photoresist that has beed exposed to uv light
    • etch - will etch anything not covered with photoresist
    • photoresist removed - solvent removes photoresist
    • diffuse - (phosphorous, aluminum for example)
