Abstract:
A system for removing an oxide material from a surface of a substrate can include a substrate tray to receive the substrate, and a cooling body to receive the substrate tray. The system may include a first temperature control element configured to control a temperature of the substrate tray and a second temperature control element configured to control a temperature of the cooling body, where the first temperature control element and the second temperature control element can be independently controlled. A method for removing oxide material from a surface of a substrate can include providing the substrate on a substrate tray having heating elements, cooling the substrate by transferring heat from the substrate tray to a cooling body, depositing a halogen-containing material on the cooled substrate while the substrate is on the cooling body, and subsequently sublimating the halogen-containing material by heating the cooled substrate by transferring heat from the substrate tray to the substrate.
