  • Patent number: 6815072
    Abstract: A method for reducing contaminants in a processing chamber 10 having chamber plasma processing region components comprising the following steps. The chamber plasma processing region components are cleaned. The chamber is then seasoned as follows. A first USG layer is formed over the chamber plasma processing region components. An FSG layer is formed over the first USG layer. A second USG layer is formed over the FSG layer. Wherein the USG, FSG, and second USG layers comprise a UFU season film. A UFU season film coating the chamber plasma processing region components of a processing chamber comprises: an inner USG layer over the chamber plasma processing region components; an FSG layer over the inner USG layer; and an outer USG layer over the FSG layer.

  • Patent number: 6759347
    Abstract: A method of reducing plasma induced damage in semiconductor devices and fluorine damage to a metal containing layer including providing a semiconductor wafer including semiconductor devices including a gate oxide and a process surface including metal lines; carrying out a first high density plasma chemical vapor deposition (HDP-CVD) process to controllably produce a silicon rich oxide (SRO) layer including a relatively increased thickness at a center portion of the process surface compared to a peripheral portion of the process surface; and, carrying out a second HDP-CVD process in-situ to deposit a fluorine doped silicon dioxide layer over the SRO layer to fill a space between the metal lines.
