摘要： A clip for a semiconductor package includes a first portion and a second portion. The first portion includes a first surface, a second surface opposite to the first surface and configured to contact a first electrically conductive component, and a stepped region between the first surface and the second surface such that the second surface has a smaller area than the first surface. The second portion is coupled to the first portion and configured to contact a second electrically conductive component. The second portion includes a third surface aligned with the first surface.

摘要： 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.
