P Type Silicon Wafer 4 inch

P Type Silicon Wafer 4 inch

Introduction:

P type silicon wafer 4 inch are semiconductors that have been doped with elements such as boron, which create “holes” in the silicon lattice. These holes act as positive charge carriers, allowing for the conduction of electricity. A 4-inch diameter wafer is a common size used in the semiconductor industry, balancing efficiency and compatibility with various fabrication processes.

Properties:

Hole Conductivity: The introduction of boron creates holes in the silicon lattice, facilitating the movement of positive charge carriers.

Lower Electron Concentration: Compared to N-type silicon, P-type silicon has a lower concentration of electrons, making it suitable for forming p-n junctions.

Good Compatibility: P-type silicon wafers are compatible with standard semiconductor fabrication processes.
