A ceramic wafer end effector—also called a wafer handling blade, robot blade or wafer transfer arm—is the part of a semiconductor robot that directly supports and transfers wafers between process chambers, load ports, aligners, inspection stations and wafer carriers. Although its geometry may appear simple, the end effector directly affects wafer positioning accuracy, transfer speed, particle generation, electrostatic discharge risk and equipment uptime. A successful ceramic wafer end effector must combine several requirements: Ceramic end effectors are used because advanced ceramics can provide dimensional precision, thermal stability, abrasion resistance and low-contamination wafer contact. Some wafer-handling systems also use ESD-safe ceramic materials to dissipate accumulated static charge. This guide explains how […]
