  • Publication number: 20090017619
    Abstract: A metal suicide layer is fabricated in a semiconductor device. A first metal layer is deposited on a silicon substrate formed with an S interlayer dielectric having a contact hole through PVD. A second metal layer is deposited on the first metal layer through any one of CVD and ALD. Annealing is performed on the silicon substrate which is formed with the first and second metal layers to form the metal silicide. The portions of the second metal layer and the first metal layer which have not reacted during annealing are removed.

  • Publication number: 20090011150
    Abstract: A conventional plasma applied ALD apparatus has a problem in that physical shock is directly imposed on a substrate and a thin film thereby damaging the thin film. Further, many reports have said that since an apparatus for controlling plasma energy is not arranged well, the thin film is not formed uniformly due to plasma nonuniformity. Therefore, there is provided a remote plasma atomic layer deposition apparatus using a DC bias comprising: a reaction chamber having an inner space; a substrate supporting body on which a substrate on which a thin film is to be formed is loaded arranged at one side of the inner space of the reaction chamber; a remote plasma generating unit arranged outside of the reaction chamber to supply a remote plasma into the inner space of the reaction chamber; a DC bias unit controlling energy of the remote plasma; and a source gas supply unit supplying a source gas for forming the thin film into the reaction chamber.

  • Patent number: 7420217
    Abstract: Light emitting LEDs devices comprised of LED chips that emit light at a first wavelength, and a tinted thin film layer over the LED chip that changes the color of the emitted light. For example, a blue-light emitting LED chip can be used to produce white light. The tinted thin film layer beneficially consists of ZnSe, CeO2, Al2O3, or Y2O3:Ce that is deposited using a chemical vapor deposition process, such as metal organic chemical vapor deposition (MOCVD), atomic layer chemical vapor deposition (ALD), plasma enhanced MOCVD, plasma enhanced ALD, and/or photo enhanced CVD. Suitable CVD precursors include Alkoxide, ?-dikeonate, Metalloscene, Alkys, DMZn, DEZe, H2Se, DMSe, TbuSe, and DESe.
