Abstract
Heights of wafers in a front opening unified pod are identified by using an end effector and a front sensor arranged thereon, such that the end effector can be positioned at the appropriate height when retrieving one of the wafers, so as to avoid colliding with a wafer stored inside the front opening unified pod. Wafer backside properties can also be detected by the end effector, so as to report defects and contaminants on the wafer.
