Abstract
A clip for attaching a semiconductor to a heat sink comprises an arcuate section having a lip which contacts a projection on a heat sink so that the remainder of the arcuate section is disposed over the projection, the arcuate section also having a central stiffening rib. The clip further comprises a plate extending from the end of the arcuate section opposite its lip, the plate having sidewalls which form a semiconductor opening. When the clip is in place on the heat sink, the clip is flexed, and the plate is forced against a semiconductor, holding it in place against the heat sink.
