    摘要: A vacuum deposition system comprises a vacuum vessel, an evaporation source holder provided in the vacuum vessel for holding an evaporation substance and a holding jig provided in the vacuum vessel for holding a substrate facing the evaporation source. An adhesion-prevention member is provided at outer peripheries of the evaporation source and the holding jig along an inner wall of the vacuum vessel across a region from a position facing a lateral part of the evaporation source holder to a position facing a lateral part of the holding jig. The adhesion-prevention member is spaced apart from the inner wall of the vacuum vessel. The adhesion-prevention member includes members slanted diagonally downward from the central part side toward the inner wall. Thereby, the adhesion-prevention member prevents an evaporant from the evaporation source from adhering to the inner wall of the vacuum vessel.

    摘要: A process for fabricating a MONOS device having a buried bit-line includes providing a semiconductor substrate and forming an ONO structure overlying the semiconductor substrate. Thereafter, a hard mask layer is formed to overlie ONO structure, the hard mask layer having an upper surface. To form a trench for the buried bit-line, an etch process is performed on the ONO structure. Thereafter, silicon dioxide is deposited to fill the trench. To control a thickness of the deposited silicon dioxide, a chemical-mechanical-polishing process is performed to planarize the silicon dioxide and form a planar surface continuous with the upper surface of the hard mask layer. Finally, the hard mask layer is removed and the remaining silicon dioxide forms a uniform bit-line oxide layer.

    摘要: A drain (7) includes a lightly-doped shallow impurity region (7a) aligned with a control gate (5), and a heavily-doped deep impurity region (7b) aligned with a sidewall film (8) and doped with impurities at a concentration higher than that of the lightly-doped shallow impurity region (7a). The lightly-doped shallow impurity region (7a) leads to improvement of the short-channel effect and programming efficiency. A drain contact hole forming portion (70) is provided to the heavily-doped impurity region (7b) to reduce the contact resistance at the drain (7).
