  • Publication number: 20040043638
    Abstract: After a lower silicon oxide film is formed on a silicon region, a silicon film is formed on the lower silicon oxide film by, for example, a thermal CVD method. Subsequently, the silicon film is completely nitrided by a plasma nitriding method to be replaced by a silicon nitride film. Subsequently, a surface layer of the silicon nitride film is oxidized by a plasma oxidizing method to be replaced by an upper silicon oxide film. An ONO film as a multilayered insulating film composed of the lower silicon oxide film, the silicon nitride film, and the upper silicon oxide film is formed.

  • Patent number: 6690580
    Abstract: This disclosure describes use of dielectric islands embedded in metallized regions of a semiconductor device. The islands are formed in a cavity of a dielectric layer, as upright pillars attached at their base to an underlying dielectric. The islands break up the metal-dielectric interface and thus resist delamination of metal at this interface. The top of each island pillar is recessed from the cavity entrance by a selected vertical distance. This distance may be varied within certain ranges, to place the island tops in optimal positions below the top surface plane of the dielectric. Metallization introduced into the cavity containing the islands, submerges the island tops to at least a minimum distance to provide a needed minimum thickness of continuous metal. The continuous metal surface serves favorably as a last metal layer for attaching solder or for bump-bonding package to the IC; and also serves as an intermediate test or probe pad in an interior layer.

    Abstract: Irradiation lamps of an ultraviolet-light irradiation apparatus are uniformly cooled to achieve an appropriate temperature of the walls of the lamps and the ultraviolet light emitted from the lamps is efficiently reflected toward an object to be irradiated so that the ultraviolet light is efficiently irradiated onto the object to be irradiated. A plurality of low-pressure mercury lamps are arranged in parallel. A reflective mirror is arranged above the low-pressure mercury lamps so as to reflect the ultraviolet light emitted by the low-pressure mercury lamps. An exhaust passage defined by the reflective mirror suctions air around the low-pressure mercury lamps and exhausts the suctioned air to outside. The reflective mirror has a plurality of openings arranged along a longitudinal direction of the low-pressure mercury lamps, and a part of the openings has a size different from a size of other parts of the openings.

  • Patent number: 6096648
    Abstract: A method of metallizing a semiconductor chip with copper including an inlaid low dielectric constant layer. The method includes the step of depositing a barrier layer on the surface of the semiconductor chip. Next, a copper seed layer is deposited on the barrier layer, and then the copper seed layer is annealed. Microlithography is then performed on the semiconductor chip to form a plurality of wiring line paths with a patterned photoresist layer. After the wiring line paths are formed a copper conductive layer is electroplated to the surface of the semiconductor chip. Next, the patterned photoresist layer is stripped off of the surface of the semiconductor chip. In addition, portions of the barrier layer and the copper seed layer that were covered by the patterned photoresist layer are also removed. A low dielectric constant layer is then deposited on the semiconductor chip to fill the gaps between the newly created copper conductive lines.

    Abstract: An improved rare probability connection call registration method which utilizes automatic congestion level (ACL) information within a release message for an asynchronous transfer mode (ATM) switching system. The method includes the steps of setting a predetermined threshold value, receiving a call releasing message, checking automatic congestion level (ACL) information in the call release message, and determining whether an ACL information is set. When the ACL information is not set continuous checks are made, and the method continues by increasing the count value when the ACL information is set, and it is determined whether the value of the ACL counter is greater than a predetermined threshold value.
