Patent ID: 7372142

Claim:
A vertical conduction power electronic device package, comprising: at least a metal frame suitable to house at least a plate or first semiconductor die having at least a first and a second conduction terminal on respective opposed sides of said first semiconductor die, said first conduction terminal being in contact with said metal frame; wherein the vertical conduction power electronic device package comprises at least one first intermediate frame arranged in contact with said second conduction terminal; wherein the vertical conduction power electronic device package comprises at least a second intermediate frame arranged in contact with said first semiconductor die, in correspondence with a third conduction terminal arranged on the same side as said second conduction terminal; wherein a second semiconductor die comprises a third conduction terminal arranged on the same side as said second conduction terminal, said second conduction terminal being arranged in contact with said at least one first intermediate frame and said third conduction terminal being arranged in contact with said second intermediate frame; wherein said first and second intermediate frames respectively have a flat portion, a second S-shaped portion and a flat free end being adjacent to each other; wherein said flat free ends of said first and second intermediate frames are coplanar to each other; and wherein said metal frame comprises a flat portion, with substantially rectangular plan, and two curved gull-wing-shaped portions, rising on parallel sides of said flat portion and on the same side as a plane Q defined by said flat portion, said curved gull-wing-shaped portions having respective flat free ends being coplanar to said flat free ends of said first and second intermediate frames.
