Abstract
A multi-layer passivation barrier ( ) for, and a method of, passivating a superconducting layer ( ) of a microelectronic device ( ). The passivation barrier includes a passivating layer ( ) and a barrier buffering layer ( ). The passivating layer provides a barrier to moisture, salts, alkali metals and the like located outside the device. The passivating layer also provides a barrier to outdiffusion of oxygen from the superconducting layer. The buffering layer permits oxygen to diffuse therethrough and provides a barrier to prevent diffusion of one or more constituent chemical elements of the passivating layer into the superconducting layer. The method includes the steps of depositing the barrier buffering layer ( ) onto the superconducting layer ( ) and depositing the passivating layer ( ) onto the buffering layer.
