silicon wafer production
Resistivity of Silicon Wafers: The resistivity of silicon wafers is the degree to which the silicon material impedes the flow of electric current, which is one of the important electrical properties of silicon wafers.
Resistivity is a key parameter of silicon wafers, which affects the performance of semiconductor devices.
The resistivity of a silicon wafer is determined by its doping level. undoped silicon has a high resistivity, while impurity atoms introduced through doping form carriers and lower the resistivity.
p-type silicon is doped with trivalent elements such as boron, and n-type silicon is doped with pentavalent elements such as phosphorus. high purity silicon has a high resistivity as the impurities provide additional carriers.
High-quality production of silicon wafers is the cornerstone of the modern electronics industry, and precise control of their resistivity and extreme surface cleanliness are key to ensuring high-performance electronics.
