A semiconductor device having a local interconnection layer and a method
for manufacturing the same are provided. A local interconnection layer is
formed in an interlayer dielectric (ILD) layer on an isolation layer and
a junction layer, for covering a semiconductor substrate, the isolation
layer, and a gate pattern. An etch stopper pattern having at least one
layer for preventing the etching of the isolation layer is formed under
the local interconnection layer. The etch stopper pattern having at least
one layer for preventing the etching of the isolation layer can be
included when forming the local interconnection layer, thereby preventing
leakage current caused by the etching of the isolation layer, improving
the electrical characteristics of a semiconductor device, and improving
the yield of a process of manufacturing a semiconductor device.
