Some implementations described herein include operating components in a lithography system at variable speeds to reduce, minimize, and/or prevent particle generation due to rubbing of or collision between contact parts of the components. In some implementations, a component in a path of transfer of a semiconductor substrate in the lithography system is operated at a relatively high movement speed through a first portion of an actuation operation, and is operated at a reduced movement speed (e.g., a movement speed that is less than the high movement speed) through a second portion of the actuation operation in which contact parts of the component are to interact. The reduced movement speed reduces the likelihood of particle generation and/or release from the contact parts when the contact parts interact, while the high movement speed provides a high semiconductor substrate throughput in the lithography system.

A substrate treatment apparatus includes a transport part to transport a transparent rectangular substrate, a substrate support part to support the substrate, light generators to irradiate two different lights onto the moving substrate, and sense the irradiated lights, and a controller to determine a posture of the substrate with reference to the sensed lights and control the transport part such that the substrate is seated on the substrate support part in a default posture that is preset. The controller determines the posture of the transparent rectangular substrate with respect to the default posture using a time difference between a time point at which a first light of the two different lights is not transmitted through an edge of the transparent rectangular substrate and a time point at which a second light of the two different lights is not transmitted through the edge of the transparent rectangular substrate.
