p-type silicon
P-type silicon is doped with the trivalent elements boron or aluminum to form cavities. The holes have a positive charge in this material, which results in p-type silicon wafers exhibiting positive conductivity properties.
Used in semiconductor devices are widely used in the manufacture of diodes, transistors, integrated circuits and traditional photovoltaic devices such as solar panels .
p-type silicon
The resistivity of a P-type silicon wafer is the magnitude of the resistance of the P-type silicon material per unit length and per unit cross-sectional area.
It is closely related to the concentration of boron doping. In integrated circuit manufacturing, it is often necessary to use P-type silicon wafers with high resistivity because high resistivity reduces leakage currents in circuits and improves the performance and reliability of circuits.
The resistivity of P-type wafers is also affected by temperature, light, and other factors, so the impact of these factors on wafer performance needs to be considered in practical applications.
