Abstract

A semiconductor package includes a metallic substrate, the metallic substrate including a roughened surface, a semiconductor die including bond pads, and an adhesive between the roughened surface of a topside of the metallic substrate and the semiconductor die, therein bonding the semiconductor die to the metallic substrate. The adhesive includes a resin. The metallic substrate further includes a groove about a perimeter of the semiconductor die on the roughened surface, the groove having a surface roughness less than a surface roughness of the roughened surface of the metallic substrate. The groove straddles the topside and a sidewall of the metallic substrate.
