Study Notes

Semiconductor Basics

  • Semiconductors are typically grown using the Czochralski technique for single crystal growth.

Semiconductor Materials

  • Silicon (Si) has replaced Germanium (Ge) as the most widely used semiconductor material.
  • Silicon replaced Germanium due to its better oxide quality and higher purity, leading to improved semiconductor performance.

Periodic Table Location

  • Semiconductor elements are located in Group IV of the periodic table.

Intrinsic Semiconductors

  • Intrinsic semiconductors have a carrier density dependent on temperature.

Integrated Circuits and Discrete Devices

  • Silicon (Si) is the most common semiconductor material used in integrated circuits and discrete devices.

Crystal Structure

  • Semiconductors have a diamond cubic crystal structure.

Fermi-Level

  • The intrinsic Fermi-level in semiconductors lies at the middle of the bandgap.
