摘要:
A method of fabricating a device includes depositing a electromigration (EM) resistive material in an etched trench formed in a substrate and a wiring layer. The EM resistive material is formed in electrical contact with an underlying diffusion barrier layer and wiring layer. The method further includes forming a via structure in electrical contact with the EM resistive material and the wiring layer. The method results in a structure which prevents an open circuit.
