  • Patent number: 7521702
    Abstract: An object of the present invention is to provide an extreme ultraviolet light source target which can emits extreme ultraviolet light with high emission efficiency. A solid target made of heavy metal or heavy-metal compound and having a density 0.5 to 80% that of the crystal density is used. When the target is irradiated with a laser beam, plasma of the heavy metal contained in the target is generated, and extreme ultraviolet light having a predetermined wavelength which corresponds to the kind of the heavy metal is emitted from the plasma. When the density of the target is made to be smaller than the crystal density as described above, space distribution of the density of the generated plasma can be controlled, and the region in which plasma absorbs energy of the laser beam overlaps the region in which the plasma emits the extreme ultraviolet light. Thus, emission efficiency can be improved, preventing energy loss.

  • Patent number: 6744070
    Abstract: In a thin-film transistor to be used in an active matrix liquid crystal display device, each of a gate signal line, a source signal line, and a drain extraction electrode has a three-layer structure. Specifically, each of these members is made up of a lower layer made of a titanium film, an intermediate layer made of an aluminum film, and an upper layer made of a titanium film containing nitrogen. Since the respective upper layers, in contact with a gate insulating film or an interlayer insulating film made of a silicon nitride film, are made of titanium films containing nitrogen, they have superior adhesion to the silicon nitride film. Consequently, film peeling, etc. during the manufacturing process can be suppressed. Further, providing the titanium film beneath the aluminum film contributes to reduction of the resistance of the aluminum film.
