  • Publication number: 20240139901
    Abstract: The present disclosure provides a tray assembly having a dual-structure. The tray assembly comprises an upper tray and a lower tray. The lower tray is capable of being easily disengaged from the upper tray by use of a dovetail joint that allows the lower tray to slidably move relative to the upper tray. The tray assembly also utilizes magnets to reduce the use of mechanical joints. The combination of the magnets together with the dovetail joint provides a quick and efficient way of sliding the lower tray in and out from the upper tray. The lower tray having a collection region collects any external, foreign materials generated during a chemical mechanical polishing/planarizing process. After the cleaning process, the lower tray can be slid back into the upper tray for use.
