Abstract: A wiring structure includes an etch stop film disposed on a substrate. A first insulating film is disposed on the etch stop film. A first wiring layer extends in a vertical direction perpendicular to an upper surface of the substrate and extends through the first insulating film and the etch stop film. A sidewall of the first wiring layer forms a first inclination angle of about 88 degrees to about 90 degrees with respect to a first horizontal direction parallel to the upper surface of the substrate. A surface of the first insulating film and a surface of the etch stop film in direct contact with the first wiring layer have a carbon (C) concentration less than or equal to about 3 at %.

Abstract: A data transmitter includes a transmitting circuit configured to transmit data, the data including alternating odd-numbered data and even-numbered data. The transmitting circuit includes a first flip flop configured to receive the odd-numbered data and generate retimed odd-numbered data, and a second flip flop configured to receive the even-numbered data and generate retimed even-numbered data. The data transmitter includes a clock transmitting circuit configured to supply a clock signal to the transmitting circuit, the clock transmitting circuit including a clock driver configured to transmit the clock signal to a receiver that receives the data.
