What Are Silicon Wafers?

Silicon wafers are thin slices of crystalline silicon used as substrates for fabricating semiconductor devices. These wafers are made by slicing silicon ingots into thin disks and then polishing them to achieve a smooth, defect-free surface. The wafers are subsequently used in photolithographic processes to create integrated circuits and microelectromechanical systems (MEMS).

Silicon is favored for its semiconducting properties, abundance, and compatibility with modern fabrication processes. Different wafer types include monocrystalline, polycrystalline, and doped variants based on specific applications.
