Abstract
A solid-state battery structure having a plurality of battery cells formed in a substrate, method of manufacturing the same and design structure thereof are provided. The battery structure includes a patterned cathode electrode layer formed upon the substrate and structured to form a plurality of sub-arrays of the battery cells. The battery structure further includes a plurality of fuse wires structured to interconnect at least two adjacent sub-arrays. At least one of the plurality of fuse wires is structured to be blown to disconnect an interconnection having a defective sub-array. Advantageously, the plurality of fuse wires is an integral part of the battery structure.
