Abstract
A semiconductor device includes: a first capacitor including an upper electrode, a lower electrode, an intermediate electrode arranged between the upper electrode and the lower electrode, and a shield line arranged in the same layer as the intermediate electrode; and a second capacitor, including an upper electrode, a lower electrode, and an intermediate electrode arranged between the upper electrode and the lower electrode, and arranged adjoining to the first capacitor. In the first capacitor and the second capacitor, the upper electrode, the lower electrode and the shield line are electrically connected to a ground electrode. The shield line lies between the first capacitor and the second capacitor. Accordingly, a MIM capacitor with excellent layout efficiency is provided while noise effects are reduced.
