In the semiconductor materials industry, silicon wafers can generally be divided into two categories based on resistivity: high-resistivity silicon wafers and low-resistivity silicon wafers. Standard low-resistivity silicon wafers, with their balanced electrical conductivity, moderate cost, and ability to support both sensing and power applications, play an essential role in consumer electronics, automotive electronics, and power devices.
Mirror polished wafers are inspected through a combination of visual surface examination, automated defect detection, roughness measurement, thickness testing, flatness evaluation, particle inspection, and edge-quality checks. A mirror polished silicon wafer must provide a smooth and clean surface suitable for epitaxy, lithography, bonding, coating, or device fabrication.
