Wafer and Die Alignment
Accurately align wafer and dies to ensure reliable performance
Many steps of the semiconductor manufacturing process require highly precise alignment, such as the photolithography process, wafer probe and test, wafer mounting, and dicing. To meet industry demand, semiconductor manufacturers use high-speed automation production systems that require minimal intervention. Poorly performing vision alignment systems stop more frequently for manual intervention and maintenance, which disrupts the production process and adds to support costs. In addition to production inefficiencies, poor alignment can decrease wafer yields and electrical functionality of die circuits.
