Patent ID: 11469123

Abstract:
A method for detecting positions of replacement parts, wafers, or empty carriers for a replacement part stored at a replacement parts storage container is provided. A container is received at a at a load port of a factory interface of an electronics processing system. The container is configured to store replacement parts for a process chamber of the electronics processing system. A robot arm is moved according to a first mapping pattern to identify, using a detection system at a distal end of an end effector of the robot arm, positions of one or more replacement parts in the container. Regions of the container that do not contain replacement parts are determined. The robot arm is moved according to a second mapping pattern to identify, within the regions of the container that do not contain replacement parts, using the detection system, a position in the container of at least one of a wafer or an empty carrier for a replacement part. A mapping of positions of the one or more replacement parts and of positions of at least one of the empty carrier or the wafer in the container is recorded in a storage medium.
