Abstract
A semiconductor structure is provided. The semiconductor structure includes a substrate, an isolation feature, a word line and a doped region. The substrate has an active region. The isolation feature is disposed in the substrate to define the active region. The word line is buried in the substrate and extends across the active region and the isolation feature. The word line includes a first conductive structure and a second conductive structure disposed on the first conductive structure. The doped region is disposed in the active region and adjacent to the word line, wherein a top surface of the first conductive structure is below a bottom surface of the doped region.
