Abstract: A first semiconductor layer serves as a first implanted layer of a first conductivity type. A second semiconductor layer of a second conductivity type is provided under the first semiconductor layer. The second conductivity type is opposite to the first conductivity type. The second semiconductor layer is buried in an epitaxial layer grown above a substrate. The second semiconductor layer becomes fully depleted when an appropriate bias voltage is applied to the device.
