Abstract
A teaching substrate is loaded into a load port of an equipment front-end module (EFEM) of a fabrication or inspection tool. The EFEM includes a substrate-handling robot. The teaching substrate includes a plurality of sensors and one or more wireless transceivers. The tool includes a plurality of stations. With the teaching substrate in the EFEM, the substrate-handling robot moves along an initial route and sensor data are wirelessly received from the teaching substrate. Based at least in part on the sensor data, a modified route distinct from the initial route is determined. The substrate-handling robot moves along the modified route, handling the teaching substrate. Based at least in part on the sensor data, positions of the plurality of stations are determined.
