Abstract
An isolation device for isolating a first signal of a first circuit from a second circuit disclosed. The isolation device may have a substrate and a plurality of metal layers disposed on the substrate. The isolation device comprises a first plate that is electrically coupled to the first circuit, and a second plate that is electrically coupled to the second circuit. The first plate is configured to transmit the first signal from to a second plate that is electrically isolated from the first plate. The first plate and the second plate is surrounded by an isolation material. The isolation device further comprises at least one trench that extend at least partially through the isolation material in a direction that is substantially perpendicular to the first plate and the second plate. The at least one trench may circumscribe one of the first plate and the second plate.
