The apparatus and methods have utility to horizontally-disposed furnaces for silicon wafers and to vertically-oriented furnaces in which larger wafers can be thermally processed. A selectively-sealable process tube encloses silicon wafers during heating of the silicon wafers to a predetermined temperature, and a heating atmosphere supply system induces through the process tube a positive flow of a process gas, such as hydrogen or argon, that is non-reactive with solid silicon at the predetermined temperature. A process tube outlet vents gas from the process tube, and an impurity sensor in the process tube outlet detects oxygen and moisture in the vented gas to verify the purity of the atmosphere surrounding the wafers during thermal processing.

  • Patent number: 7972441
    Abstract: A method and apparatus for oxidizing materials used in semiconductor integrated circuits, for example, for oxidizing silicon to form a dielectric gate. An ozonator is capable of producing a stream of least 70% ozone. The ozone passes into an RTP chamber through a water-cooled injector projecting into the chamber. Other gases such as hydrogen to increase oxidation rate, diluent gas such as nitrogen or O2, enter the chamber through another inlet. The chamber is maintained at a low pressure below 20 Torr and the substrate is advantageously maintained at a temperature less than 800° C. Alternatively, the oxidation may be performed in an LPCVD chamber including a pedestal heater and a showerhead gas injector in opposition to the pedestal.

  • Publication number: 20100252547
    Abstract: An approach for optimizing the thermal budget during a pulsed heating process is disclosed. A heat sink or thermal transfer plate is configured and positioned near an object, such as a semiconductor wafer, undergoing thermal treatment. The heat sink is configured to enhance the thermal transfer rate from the object so that the object is rapidly brought down from the peak temperature after an energy pulse. High thermally-conductive material may be positioned between the plate and the object. The plate may include protrusions, ribs, holes, recesses, and other discontinuities to enhance heat transfer and avoid physical damage to the object during the thermal cycle. Additionally, the optical properties of the plate may be selected to allow for temperature measurements via energy measurements from the plate, or to provide for a different thermal response to the energy pulse. The plate may also allow for pre-heating or active cooling of the wafer.
