  • Tetraode field-emission display and method of fabricating the same
    Patent number: 7081703
    Abstract: A tetraode field-emission display and a method of fabricating the same are disclosed. A mesh is disposed between an anode plate and a cathode plate. The mesh has a gate layer and a converging electrode layer separated by an insulation layer to form a sandwich structure. The mesh has a plurality of apertures in correspondence with each set of anode and cathode. A glass plate is placed between the mesh and the anode to serve as a spacer. The converging electrode layer is facing the anode plate, such that the divergent range of an electron beam emitted by an electron emission source can be restricted. Thereby, the electron beam can impinge the corresponding anode more precisely.

  • Material handling system enabling enhanced data consistency and method thereof
    Publication number: 20060155409
    Abstract: Material handling systems that enable enhanced data consistency, and methods thereof, are disclosed. Behavior and life cycle of a semiconductor product for a material handling system are modeled in a set of finite states and trigger paths. A trigger event corresponding to a second finite state is generated when a transfer state of the product changes from a first finite state to a second finite state along trigger paths. Next, it is determined whether the trigger event complies with a predetermined control rule. Transport data between manufacturing execution and material handling systems is synchronized by message exchange.

    Publication number: 20060138927
    Abstract: A method and a structure for a converging-type electron-emission source of a field-emission display are disclosed. A substrate is provided, and a silver paste is used to form a first electrode layer on the substrate by the process such as thick-film photolithography screen-printing. At least one pit is formed in the first electrode layer by etching, for example. A passivation layer is formed on the first electrode layer around the pit. A second electrode layer is formed in the recess by photolithography or electrophoresis, for example. Preferably, the second electrode layer is formed with a top surface lower than a periphery of the pit, such that a converging opening of the second electrode layer is formed over the second electrode layer. The passivation layer is then removed, followed by a step of sintering process.
