  • Publication number: 20060249175
    Abstract: An ultraviolet (UV) cure chamber enables curing a dielectric material disposed on a substrate and in situ cleaning thereof. A tandem process chamber provides two separate and adjacent process regions defined by a body covered with a lid having windows aligned respectively above each process region. One or more UV bulbs per process region that are covered by housings coupled to the lid emit UV light directed through the windows onto substrates located within the process regions. The UV bulbs can be an array of light emitting diodes or bulbs utilizing a source such as microwave or radio frequency. The UV light can be pulsed during a cure process. Using oxygen radical/ozone generated remotely and/or in-situ accomplishes cleaning of the chamber. Use of lamp arrays, relative motion of the substrate and lamp head, and real-time modification of lamp reflector shape and/or position can enhance uniformity of substrate illumination.

  • Publication number: 20050103266
    Abstract: A method and apparatus that reduces the time required to clean a processing chamber employing a reactive plasma cleaning process. A plasma is formed in an Astron fluorine source generator from a flow of substantially pure inert-source gas. After formation of the plasma, a flow of a fluorine source gas is introduced therein such that the fluorine source flow accelerates at a rate no greater than 1.67 standard cubic centimeters per second2 (scc/s2). In this fashion, the plasma contains a plurality of radicals and dissociated inert-source gas atoms, defining a cleaning mixture. The ratio of inert-source gas to fluorine source is greater than 1:1.

  • Patent number: 6814087
    Abstract: A method of removing residue from a substrate processing chamber. In one embodiment the method comprises flowing an inert gas into a remote plasma chamber and forming a plasma within the chamber; maintaining the plasma while creating a plurality of reactive fluorine species by flowing a fluorine-containing gas into the remote plasma chamber and increasing a flow rate of a fluorine-containing gas from a first flow rate to a second flow rate higher than the first flow rate; and introducing the plurality of reactive fluorine species into the substrate processing chamber.

  • Patent number: 6311959
    Abstract: Method and apparatus generate a mixture of the vapor of an organic liquid such as tetraethylorthosilicate (TEOS) and an inert gas such as helium. The ratio of organic vapor to inert gas in the mixture is accurately and continuously controlled as required in semiconductor manufacturing. The apparatus encloses a bubbler chamber which is filled with an organic liquid (e.g., TEOS) to a set level that is automatically maintained. The liquid is also maintained at an exact temperature (e.g., 75° C.). Inert gas (e.g., helium) flows into the bubbler chamber at a controlled rate and continuously evaporates some of the liquid therein. The flow of liquid into the bubbler chamber is monitored by a liquid control circuit, and flow of gas is controlled by a gas control circuit. A feedback signal from the liquid control circuit to the gas control circuit incrementally adjusts gas flow into the bubbler chamber to keep the liquid therein at the set level.

  • Patent number: 6300255
    Abstract: There are provided a method and apparatus for forming by chemical vapor deposition on large diameter (e.g., 300 mm) semiconductive wafers thin insulating layers of silicon oxide (SiO2) having high uniformity from rim to rim across any diameter through the centers of the wafers. Such high degree of uniformity of the layers is obtained by directing separately a first reactive gas stream and a second reactive gas stream into close proximity to an exposed surface of a wafer to a be coated by the gasses with an insulating layer, the gas streams when mixed together reacting with each other to deposit an insulating layer on a wafer; forming a whirlpool-like swirling mixture of the first and second gas streams to thoroughly mix together the gasses thereof; forming a highly uniform mixture of the reactive gasses; and promptly flowing the mixture of reactive gasses over and upon the surface of the wafer. The apparatus also provides dual wafer processing chamber cavities.
