Product Description
Boron and phosphorus doped silicon wafers are specialized semiconductor substrates engineered with precise electrical properties. These wafers serve as the foundation for manufacturing advanced electronic components and integrated circuits.
Semiconductor Wafer Technology
Silicon wafers are thin slices of pure crystallized silicon. Undoped or intrinsic silicon wafers provide the base material, while the addition of dopants like boron or phosphorus enables precise control over electrical characteristics. Boron doping creates P-type wafers with positive charge carriers, while phosphorus doping produces N-type wafers with negative charge carriers.
