Abstract
A semiconductor device according to the disclosure includes a substrate, a transistor connected to the substrate, and a wiring structure including contact wirings electrically connected to the transistor. The wiring structure further includes a first wiring insulating layer, a first material layer contacting the first wiring insulating layer, a second material layer contacting the first material layer, and a second wiring insulating layer contacting the second material layer. The first material layer includes SiN, and the second material layer includes SiCN. A dielectric constant of the first wiring insulating layer is greater than a dielectric constant of the second wiring insulating layer.
