    摘要： A method of forming a metal layer having excellent thermal and oxidation resistant characteristics using atomic layer deposition is provided. The metal layer includes a reactive metal (A), an element (B) for the amorphous combination between the reactive metal (A) and nitrogen (N), and nitrogen (N). The reactive metal (A) may be titanium (Ti), tantalum (Ta), tungsten (W), zirconium (Zr), hafnium (Hf), molybdenum (Mo) or niobium (Nb). The amorphous combination element (B) may be aluminum (Al), silicon (Si) or boron (B). The metal layer is formed by alternately injecting pulsed source gases for the elements (A, B and N) into a chamber according to atomic layer deposition to thereby alternately stack atomic layers. Accordingly, the composition ratio of a nitrogen compound (A—B—N) of the metal layer can be desirably adjusted just by appropriately determining the number of injection pulses of each source gas. According to the composition ratio, a desirable electrical conductivity and resistance of the metal layer can be accurately obtained. The atomic layers are individually deposited, thereby realizing excellent step coverage even in a complex and compact region. A metal layer formed by atomic layer deposition can be employed as a barrier metal layer, a lower electrode or an upper electrode in a semiconductor device.

    摘要： A method of manufacturing a barrier metal layer uses atomic layer deposition (ALD) as the mechanism for depositing the barrier metal. The method includes supplying a first source gas onto the entire surface of a semiconductor substrate in the form of a pulse, and supplying a second source gas, which reacts with the first source gas, onto the entire surface of the semiconductor substrate in the form of a pulse. In a first embodiment, the pulses overlap in time so that the second source gas reacts with part of the first source gas physically adsorbed at the surface of the semiconductor substrate to thereby form part of the barrier metal layer by chemical vapor deposition whereas another part of the second source gas reacts with the first source gas chemically adsorbed at the surface of the semiconductor substrate to thereby form part of the barrier metal layer by atomic layer deposition. Thus, the deposition rate is greater than if the barrier metal layer were only formed by ALD. In the second embodiment, an impurity-removing gas is used to remove impurities in the barrier metal layer. Thus, even if the gas supply scheme is set up to only use ALD in creating the barrier metal layer, the deposition rate can be increased without the usual accompanying increase in the impurity content of the barrier metal layer.

    摘要： A method for forming a metal layer located over a metal underlayer of a semiconductor device, using a metal halogen gas. The method involves supplying a predetermined reaction gas into a reaction chamber for a predetermined period of time prior to deposition of the metal layer. The reaction gas has a higher reactivity with an active halogen element of a metal halogen gas supplied to form the metal layer, compared to a metal element of the metal halogen gas. As the metal halogen gas is supplied into the reaction chamber, the reaction gas reacts with the halogen radicals of the metal halogen gas, so that the metal underlayer is protected from being contaminated by impurities containing the halogen radicals.

    摘要： A method of forming a cobalt disilicide layer and a method of manufacturing a semiconductor device using the same are provided. The method of forming a cobalt disilicide layer includes forming a cobalt layer on at least a silicon surface of a semiconductor device using metal organic chemical vapor deposition by supplying a cobalt precursor having a formula Co2(CO)6(R1—C≡C—R2), where R1 is H or CH3, and R2 is hydrogen, t-butyl, phenyl, methyl, or ethyl, as a source gas. Then, a capping layer is formed on the cobalt layer. A first thermal treatment is then performed on the semiconductor device in an ultra high vacuum, for example, under a pressure of 10−9-10−3 torr, to react silicon with cobalt. Cobalt unreacted during the first thermal treatment and the capping layer are then removed and a second thermal treatment is performed on the semiconductor device to form the cobalt disilicide (CoSi2) layer.
