    Abstract: A microdevice assembly (20) that includes a device microstructure (22), a housing (30), and a fine grain getter layer (40). The housing (30) has a base portion (32) and a lid (34). The device microstructure (22) is attached to the base portion (32) and the lid (34) is hermetically sealed to the base portion (32). The housing (30) defines a cavity (38) surrounding the device microstructure (22). The fine grain getter layer (40) is on an interior side (42) of the lid (34) for maintaining a vacuum in the cavity (38) surrounding the device microstructure (22). The lid (34) may be made of metal or have at least a metallic surface in the region where the fine grain getter layer (40) is applied. The fine grain getter layer (40) has a sub-micron grain size. There is also a method for making the microdevice assembly (20).

  • Patent number: 6787982
    Abstract: A side bar for a flat panel display device is disposed between a faceplate and a backplate of the flat panel display device such that it seals the two plates and maintains a constant gap between the two plates. The side bar includes contacting surfaces confronting the facing surfaces of the faceplate and the backplate, and a paste-receiving groove formed on each contacting surface in a longitudinal direction. The paste-receiving groove is provided with adhesive paste for sealing the faceplate to the backplate. The present invention further provides a side bar which has a getter-receiving groove formed thereon adjacent to the paste-receiving groove. The getter-receiving groove is provided with a getter used for improving the vacuum degree of the flat panel display device. The present invention also encompasses a flat panel display device employing the side bar described above, and a method of manufacturing the side bar for a flat panel display device.

  • Patent number: 6784613
    Abstract: A non-evaporating getter maintains the adsorbability for the residual gases, and in addition, secures sufficient characteristics particularly even when it experiences a high-temperature and low-vacuum condition in the fabrication process of a display unit. The non-evaporating getter includes a substrate having no function as a getter and a polycrystalline film arranged on the substrate which film contains Ti as the main component and has a host of voids in the interior thereof. A non-evaporating getter is made by forming a polycrystalline film containing Ti as the main component on the concavo-convex surface of the substrate which substrate has concavities and convexities on a surface thereof and has no function as a getter.
