    摘要: A method for forming a layer on a substrate includes providing a substrate in a reactor of a semiconductor processing system, the reactor having a divider separating an upper chamber from a lower chamber and a substrate holder therein, the substrate having upper and lower surfaces. The wafer is positioned within the reactor using the substrate holder such that the upper surface bounds the upper chamber, a silicon-containing gas is flowed through the upper chamber to deposit a layer of the upper surface, and a halogen-containing gas is flowed through the lower chamber to etch a deposited film on at least one wall bounding the lower chamber while flowing the silicon-containing gas through the upper chamber. Semiconductor processing systems are also described.

    摘要: 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.
