A wafer frame cassette is received at a transfer port from a transfer system. A robot arm retrieves the wafer frames from the cassette and stores each wafer frame in a respective storage slot in one of a plurality of storage towers. The storage location of each wafer frame is recorded. Each wafer frame can be selectively retrieved and loaded into a wafer frame cassette by the robot arm for further processing."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Wafer frame sorter and stocker","description":"A wafer sorting and stoking system provides automated storage and retrieval of wafer frames carrying semiconductor wafers.
