Abstract
A digital isolator according to an embodiment includes a first electrode, a first insulating part, a second electrode, a second insulating part, and a first dielectric part. The first insulating part is located under the first electrode. The second electrode is located under the first insulating part. The second insulating part is located around the first electrode along a first plane perpendicular to a first direction. The first direction is from the second electrode toward the first electrode. The first dielectric part is located between the first electrode and the second insulating part in a second direction along the first plane. The first dielectric part contacts the first electrode. A relative dielectric constant of the first dielectric part is greater than a relative dielectric constant of the first insulating part.
