Abstract
An isolator includes an insulation layer and a capacitor embedded in the insulation layer. The capacitor includes: a first electrode portion arranged in the insulation layer and connected to a first pad; a second electrode portion arranged in the insulation layer and connected to a second pad; and an intermediate electrode portion arranged in the insulation layer and not connected to the first electrode portion and the second electrode portion. The intermediate electrode portion includes a first intermediate layer, a second intermediate layer, and a connector connecting the first intermediate layer and the second intermediate layer. The capacitor is formed by coupling the first electrode portion and the second electrode portion through the intermediate electrode portion.
