Abstract: A semiconductor package includes: a die pad having opposing first and second sides and lateral sides connecting the first and second sides; at least one semiconductor die arranged over the first side; an encapsulation including a first dielectric material and encapsulating the semiconductor die, the second side of the die pad being at least partially exposed from the encapsulation; and a contiguous isolation structure including a second dielectric material different from the first dielectric material and covering the second side of the die pad. The encapsulation includes at least one first trench arranged along at least a part of a contour of the second side of the die pad. The second side of the die pad includes at least one second trench arranged along at least a part of the contour of the second side of the die pad. The trenches are filled by the contiguous isolation structure.

Abstract: A semiconductor module includes: a dual-gauge leadframe having thicker and thinner parts, part of the thinner part forming a high voltage lead; a semiconductor die attached to the thicker part; and a molding compound (MC) encapsulating the die. The thicker leadframe part is disposed at a bottom side of the MC. A side face of the MC has a stepped region between the high voltage lead and thicker leadframe part. A first generally vertical part of the stepped region extends from the high voltage lead to the generally horizontal part, a generally horizontal part of the stepped region extends to the second generally vertical part, and a second generally vertical part of the stepped region extends to the bottom side of the MC. A linear dimension of the generally horizontal part as measured from the first generally vertical part to the second generally vertical part is at least 4.5 mm.
