Abstract: A semiconductor package includes an insulation layer provided between a molding compound and an electromagnetic interface (EMI) layer. The insulation layer covers an exposed portion of a bond wire that extends beyond a top surface of the molding compound due to a Z-height reduction of the molding compound. The insulation layer prevents a short from occurring between the bond wire and the EMI layer.

Abstract: A semiconductor device includes a substrate, semiconductor dies on the substrate, molding compound and reinforcing blocks on the substrate. The reinforcing blocks may be provided at positions on the substrate where mechanical stresses develop in the device during singulation, such as at curves and/or discontinuous points around the outline of the substrate, to add strength to the substrate.
