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 delivering two or more mutually-reactive reaction gases when a predetermined film is deposited on a substrate, and a shower head used in the gas delivery method, function to increase the film deposition rate while preventing formation of contaminating particles. In this method, one reaction gas is delivered toward the edge of the substrate, and the other reaction gases are delivered toward the central portion of the substrate, each of the reaction gases being delivered via an independent gas outlet to prevent the reaction gases from being mixed. In the shower head, separate passages are provided to prevent the first reaction gas from mixing with the other reaction gases by delivering the first reaction gas from outlets formed around the edge of the bottom surface of the shower head. The other reaction gases are delivered from outlets formed in the central portion of the bottom surface of the shower head. Accordingly, one of the mutually-reactive gases is delivered toward the central portion of the substrate, and the others are delivered toward the edge of the substrate.

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.
摘要翻译：制造阻挡金属层的方法使用原子层沉积（ALD）作为沉积阻挡金属的机理。该方法包括以脉冲的形式将第一源气体提供到半导体衬底的整个表面上，并将与第一源气体反应的第二源气体以一脉在第一实施例中，脉冲在时间上重叠，使得第二源气体与物理吸附在半导体衬底的表面处的第一源气体的一部分反应，从而通过化学气相沉积形成阻挡金属层的一部分，而另一部分第二源气体与化学吸附在半导体衬底的表面上的第一源气体反应，从而通过原子层沉积形成阻挡金属层的一部分。因此，如果阻挡金属层仅由ALD形成，则沉积速率更大。在第二实施例中，使用杂质去除气体来除去阻挡金属层中的杂质。因此，即使将气体供给方案设定为仅使用ALD来制造阻挡金属层，也可以提高成膜速度，而不会妨碍阻挡金属层的杂质含量的增加。

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.
