  • Publication number: 20070238301
    Abstract: A batch processing system and method for chemical oxide removal (COR) is described. The batch processing system is configured to provide chemical treatment of a plurality of substrates, wherein each substrate is exposed to a gaseous chemistry, such as HF/NH3, under controlled conditions including surface temperature and gas pressure. Furthermore, the batch processing system is configured to provide thermal treatment of a plurality of substrates, wherein each substrate is thermally treated to remove the chemically treated surfaces on each substrate.

  • Publication number: 20050217799
    Abstract: A wafer heating assembly is described having a unique heater element for use in a single wafer processing systems. The heating unit includes a carbon wire element encased in a quartz sheath. The heating unit is as contamination-free as the quartz, which permits direct contact to the wafer. The mechanical flexibility of the carbon ‘wire’ or ‘braided’ structure permits a coil configuration, which permits independent heater zone control across the wafer. The multiple independent heater zones across the wafer can permit temperature gradients to adjust film growth/deposition uniformity and rapid thermal adjustments with film uniformity superior to conventional single wafer systems and with minimum to no wafer warping. The low thermal mass permits a fast thermal response that enables a pulsed or digital thermal process that results in layer-by-layer film formation for improved thin film control.

  • Publication number: 20050068519
    Abstract: A method and system are provided for monitoring status of a system component in a process chamber of a batch type processing system. The method includes exposing a system component to light from a light source and monitoring interaction of the light with the system component to determine status of the system component. The method can detect light transmission and/or light reflection from a system component during a process that can include a chamber cleaning process, a chamber conditioning process, a substrate etching process, and a substrate film formation process. The system component can be a consumable system part such as a process tube, a shield, a ring, a baffle, and a liner, and can further contain a protective coating.

  • Publication number: 20050070104
    Abstract: A method and system for monitoring status of a system component during a process. The method includes exposing a system component to a reactant gas during a process, where the reactant gas is capable of etching the system component material to form an erosion product, and monitoring release of the erosion product during the process to determine status of the system component. Processes that can be monitored include a chamber cleaning process, a chamber conditioning process, a substrate etching process, and a substrate film formation process. The system component can be a consumable system part such as a process tube, a shield, a ring, a baffle, an injector, a substrate holder, a liner, a pedestal, a cap cover, an electrode, and a heater, any of which can further include a protective coating.
