A semiconductor package includes a metallic pad and leads spaced from the metallic pad by a gap, the metallic pad including a roughened surface. The semiconductor package further includes a semiconductor die including bond pads, and an adhesive between the roughened surface of the metallic pad and the semiconductor die, therein bonding the semiconductor die to the metallic pad, wherein the adhesive includes a resin. The metallic pad further includes a groove surrounding 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 pad.
