Abstract
A semiconductor structure with ohmic contacts and variable resistance contacts has an interconnection pattern to the contacts including a first barrier metal in contact with the variable resistance contacts and a second metal contacting the barrier metal and the ohmic contacts. The barrier layer protects the amorphotized crystalline structure of the variable resistance contacts. Fabrication processes are described.
