    摘要: Cubic or metastable cubic refractory metal carbides act as barrier layers to isolate, adhere, and passivate copper in semiconductor fabrication. One or more barrier layers of the metal carbide are deposited in conjunction with copper metallizations to form a multilayer characterized by a cubic crystal structure with a strong (100) texture. Suitable barrier layer materials include refractory transition metal carbides such as vanadium carbide (VC), niobium carbide (NbC), tantalum carbide (TaC), chromium carbide (Cr3C2), tungsten carbide (WC), and molybdenum carbide (MoC).

    摘要: A method of producing a reactive powder includes providing a bulk structure of reactive material comprising a first reactant and a second reactant, the bulk structure having a preselected average spacing between the first and the second reactants; and mechanically processing the bulk structure of reactive material to produce a plurality of particles from the bulk structure such that each of the plurality of particles comprises the first and second reactants having an average spacing that is substantially equal to the preselected average spacing of the bulk structure of reactive material. The first and second materials of the plurality of particles react with each other in an exothermic reaction upon being exposed to a threshold energy to initiate the exothermic reaction and remain substantially stable without reacting with each other prior to being exposed to the threshold energy.
