  • Patent number: 9257550
    Abstract: An embodiment of an integrated electronic device formed in a body of semiconductor material, which includes: a substrate of a first semiconductor material, the first semiconductor material having a first bandgap; a first epitaxial region of a second semiconductor material and having a first type of conductivity, which overlies the substrate and defines a first surface, the second semiconductor material having a second bandgap wider than the first bandgap; and a second epitaxial region of the first semiconductor material, which overlies, and is in direct contact with, the first epitaxial region. The first epitaxial region includes a first buffer layer, which overlies the substrate, and a drift layer, which overlies the first buffer layer and defines the first surface, the first buffer layer and the drift layer having different doping levels.
    Type: Grant

  • Patent number: 8829609
    Abstract: An insulated gate semiconductor device, comprising: a semiconductor body having a front side and a back side opposite to one another; a drift region, which extends in the semiconductor body and has a first type of conductivity and a first doping value; a body region having a second type of conductivity, which extends in the drift region facing the front side of the semiconductor body; a source region, which extends in the body region and has the first type of conductivity; and a buried region having the second type of conductivity, which extends in the drift region at a distance from the body region and at least partially aligned to the body region in a direction orthogonal to the front side and to the back side.
