Structure for reducing parasitic leakage in a memory array with merged isolation and node trench construction

A semiconductor structure of merged isolation and node trench construction is presented, along with a method of fabrication, wherein an isolation implant layer is formed at the intersection of the storage node, isolation trench and field isolation region. The isolation implant layer has higher conce...
