Abstract
A semiconductor package that includes a conductive clip having an interior surface that includes a plurality of spaced raised portions, a semiconductor device having a first major surface that includes a plurality of spaced depressions each receiving one of the raised portions in the interior thereof, and a conductive adhesive disposed between each raised portion and a respective interior surface of a depression.
Claims20
A semiconductor package comprising;
- a conductive clip having an interior surface that includes spaced raised portions, wherein said spaced raised portions are structurally integral to and structurally continuous with said conductive clip so as to be part of said conductive clip;
- a semiconductor device including a semiconductor die having a first major surface that includes a plurality of spaced depressions traversing said semiconductor die;
- an electrode on said first major surface, said electrode lining said first major surface without filling said depressions entirely to provide space in each said depression in which at least a respective one of said spaced raised portions is received;
- a conductive adhesive that extends into said depressions and along said spaced raised portions and is disposed between and is in continuous contact with said spaced raised portions and said electrode on said first surface of said semiconductor die to electrically connect said semiconductor die to said conductive clip through said electrode.
