Phosphorus Doped Silicon

Phosphorus Doped Silicon

Introduction:

Phosphorus doped silicon  are a type of N-type semiconductor material created by introducing phosphorus atoms into the silicon lattice. This doping process increases the number of free electrons available for conduction, enhancing the material’s electrical properties. The 4-inch diameter wafers are commonly used in the semiconductor industry, offering a balance between efficient production and integration into various electronic devices.

Properties:

High Electron Concentration: Phosphorus acts as a donor, providing extra electrons that significantly increase the electrical conductivity of the silicon.

Shallow Donor Levels: The doping creates energy levels close to the conduction band, allowing for easier excitation of electrons, facilitating efficient charge transport.

Good Thermal Stability: These wafers exhibit excellent thermal stability, making them suitable for various electronic applications.
