ABSTRACT:
A high frequency superconducting device structure is disclosed which comprises an alkaline earth fluoride substrate with a magnesium oxide lower buffer layer on the alkaline earth substrate and an upper buffer layer epitaxial template layer on the magnesium oxide layer for providing a template for epitaxial growth of a high temperature superconducting film on the upper buffer layer, providing reduced dielectric and conducting losses at high frequencies. The disclosed structure may be incorporated into a multi-chip module (MCM) for providing very high speed interconnections.
