Clip frame semiconductor packages and methods of formation thereof

摘要

In one embodiment, a semiconductor package includes a clip frame with a first clip having a first support structure, a first lever, and a first contact portion, which is disposed on a front side of the semiconductor package. The first support structure is adjacent an opposite back side of the semiconductor package. The first lever joins the first contact portion and the first support structure. A first die is disposed over the first support structure of the first clip. The first die has a first contact pad on the front side of the semiconductor package. An encapsulant material surrounds the first die and the first clip.

1. A method of forming a semiconductor package, the method comprising:
attaching a first die over a first clip of a clip frame, the first clip having a first support structure, a first lever, and a first contact portion, the first lever joining the first contact portion and the first support structure, wherein the clip frame comprises a plurality of clips arranged next to each other and oriented in a first direction and a plurality of support beams oriented in a second direction perpendicular to the first direction, wherein each of the plurality of clips is spaced apart from another of the plurality of clips by a gap of a plurality of gaps, and wherein each of the plurality of support beams connects neighboring clips of the plurality of clips separated by a gap of the plurality of gaps; encapsulating the first clip and the first die with an encapsulating material; and singulating the clip frame to form the semiconductor package, wherein after the singulating the first contact portion is disposed on a front side of the semiconductor package and the first support structure is adjacent an opposite back side of the semiconductor package, wherein the first clip is connected to an adjacent second clip through a support beam of the plurality of support beams, and wherein the singulating cuts through the support beam.
