  • Patent number: 8283787
    Abstract: A semiconductor device includes a through-silicon-via arranged to couple a plurality of stacked semiconductor chips, an interconnection line coupled to the through-silicon-via at one side and arranged to couple the through-silicon-via to the semiconductor chip, an internal interconnection line disposed at the other side of the interconnection line and intersected with the interconnection line, and at least one first contact disposed to couple the internal interconnection line to the interconnection line. A region of the interconnection line in which the internal interconnection line is disposed is equally divided, and an area between the divided regions is removed.

  • Publication number: 20120007187
    Abstract: A gate in a semiconductor device is formed to have a dummy gate pattern that protects a gate. Metal lines are formed to supply power for a semiconductor device and transfer a signal. A semiconductor device includes a quad coupled receiver type input/output buffer. The semiconductor device is formed with a gate line that extends over an active region, and a gate pad located outside of the active region. The gate line and the gate pad are adjoined such that the gate line and a side of the gate pad form a line. Dummy gates may also be applied. The semiconductor device includes a first metal line patterns supplying power to a block having a plurality of cells, a second metal line pattern transferring a signal to the cells, and dummy metal line patterns divided into in a longitudinal direction.
