  • Crucible for electron-beam evaporator
    Patent number: 10415134
    Abstract: Disclosed is a crucible that exhibits stable evaporation efficiency and durability with respect to Al, is used in an evaporation source of an electron-beam evaporator, and includes a storage unit, which includes a wall and a bottom and in which a deposition material is placed, and a wetting prevention unit that includes another wall, which is taller than the wall of the storage unit, and another bottom, and is combined with an exterior of the storage unit. The wetting prevention unit is provided so that only the wall of the storage unit is wet with Al, and accordingly, the lifespan of the crucible is lengthened. Further, contact with the ceramic material in order to prevent wetting is minimized, thereby preventing a reduction in the physical properties of the thin film due to the impurities mixed with the deposited Al.
