摘要： A layer of silicon nitride having a thickness from 0.5 nanometers to 2.4 nanometers is deposited on a substrate. A plasma nitridation process is carried out on the layer. These steps are repeated for a plurality of additional layers of silicon nitride, until a predetermined thickness is attained. Such steps can be used to provide a multilayer silicon nitride dielectric formed on a substrate having an upper surface of dielectric material with Cu and other conductors embedded within, and a plurality of steps. The multilayer silicon nitride dielectric has a plurality of individual layers each having a thickness from 0.5 nanometers to 2.4 nanometers, and the multilayer silicon nitride dielectric conformally covers the steps of the substrate with a conformality of at least seventy percent. A multilayer silicon nitride dielectric, and a multilevel back end of line interconnect wiring structure using same, are also provided.

摘要： A dielectric capping layer having a dielectric constant of less than 4.2 is provided that exhibits a higher mechanical and electrical stability to UV and/or E-Beam radiation as compared to conventional dielectric capping layers. Also, the dielectric capping layer maintains a consistent compressive stress upon post-deposition treatments. The dielectric capping layer includes a tri-layered dielectric material in which at least one of the layers has good oxidation resistance, is resistance to conductive metal diffusion, and exhibits high mechanical stability under at least UV curing. The low k dielectric capping layer also includes nitrogen content layers that contain electron donors and double bond electrons. The low k dielectric capping layer also exhibits a high compressive stress and high modulus and is stable under post-deposition curing treatments, which leads to less film and device cracking and improved device reliability.
