Abstract
An embodiment of a vertical-conduction integrated electronic device formed in a body of semiconductor material which includes: a substrate made of a first semiconductor material and with a first type of conductivity, the first semiconductor material having a first bandgap; an epitaxial region made of the first semiconductor material and with the first type of conductivity, which overlies the substrate and defines a first surface; and a first epitaxial layer made of a second semiconductor material, which overlies the first surface and is in direct contact with the epitaxial region, the second semiconductor material having a second bandgap narrower than the first bandgap. The body moreover includes a deep region of a second type of conductivity, extending underneath the first surface and within the epitaxial region.
