Abstract:
A semiconductor device includes an input/output pad, an input line of an internal circuit, and a plurality of metal lines formed on a lower portion of the input/output pad to have a buffer area overlapping with a plane area of the input/output pad, wherein one of an entirety and a portion of the plurality of metal lines included in the buffer area forms protective resistance interconnecting the input/output pad to the input line.
