  • Patent number: 12580164
    Abstract: The present disclosure generally relates to semiconductor processing tool cleaning, such as may be included in semiconductor processing for manufacturing an integrated circuit (IC). In an example, a cleaning process is performed on an interior surface of a chamber of a semiconductor processing tool. The cleaning process includes flowing a reactive gas into an interior volume of the chamber. The interior volume is defined at least in part by the interior surface. The reactive gas consists exclusively of boron trichloride (BCl3). After performing the cleaning process, a material layer over a semiconductor substrate is etched in the chamber.
